Adaptive image adjustment - javascript

What is a cool CSS3 method to ensure an image will occupy window-height with min-width:50% and max-width:100%; depending on the size of the image?
So if the image is good quality and greater than the resolution of the screen/viewport, it will behave as a background-size:cover; and if not, it will occupy atleast 50% of the screen real estate.
Thanks.
PS - If CSS3 can't do, JS method is cool but otherwise could be preferred as a fall-back
html,
body {
min-height: 100% !important;
background-color: #efefef;
color: #5c5c5c;
overflow-y: hidden;
}
html {
font-size: 10px;
}
body {
/*background: #fff;*/
margin: 0;
height: 100%;
}
#layout {
height: 100%;
max-height: 100%;
min-width: 100%;
position: absolute;
display: flex;
flex-flow: row nowrap;
justify-content: left;
align-items: center;
}
#cover {

flex: 0 0 30rem;
max-height: 100%;
width: auto;
min-width: 100%;
max-width: 100%;

You can make it like this
.the_img{
width: 100%;
max-width: 1024px;
}
For max-width you will add the width of the image so it doesn't go beneath that.

how do I vertically center content inside a div? [duplicate]

I want to center a div vertically with CSS. I don't want tables or JavaScript, but only pure CSS. I found some solutions, but all of them are missing Internet Explorer 6 support.
<body>
<div>Div to be aligned vertically</div>
</body>
How can I center a div vertically in all major browsers, including Internet Explorer 6?
Below is the best all-around solution I could build to vertically and horizontally center a fixed-width, flexible height content box. It was tested and worked for recent versions of Firefox, Opera, Chrome, and Safari.
.outer {
display: table;
position: absolute;
top: 0;
left: 0;
height: 100%;
width: 100%;
}
.middle {
display: table-cell;
vertical-align: middle;
}
.inner {
margin-left: auto;
margin-right: auto;
width: 400px;
/* Whatever width you want */
}
<div class="outer">
<div class="middle">
<div class="inner">
<h1>The Content</h1>
<p>Once upon a midnight dreary...</p>
</div>
</div>
</div>
View A Working Example With Dynamic Content
I built in some dynamic content to test the flexibility and would love to know if anyone sees any problems with it. It should work well for centered overlays also -- lightbox, pop-up, etc.
The simplest way would be the following three lines of CSS:
1) position: relative;
2) top: 50%;
3) transform: translateY(-50%);
Following is an example:
div.outer-div {
height: 170px;
width: 300px;
background-color: lightgray;
}
div.middle-div {
position: relative;
top: 50%;
-webkit-transform: translateY(-50%);
-ms-transform: translateY(-50%);
transform: translateY(-50%);
}
<div class='outer-div'>
<div class='middle-div'>
Test text
</div>
</div>
One more I can't see on the list:
.Center-Container {
position: relative;
height: 100%;
}
.Absolute-Center {
width: 50%;
height: 50%;
overflow: auto;
margin: auto;
position: absolute;
top: 0; left: 0; bottom: 0; right: 0;
border: solid black;
}
Cross-browser (including Internet Explorer 8 - Internet Explorer 10 without hacks!)
Responsive with percentages and min-/max-
Centered regardless of padding (without box-sizing!)
height must be declared (see Variable Height)
Recommended setting overflow: auto to prevent content spillover (see Overflow)
Source: Absolute Horizontal And Vertical Centering In CSS
Now the Flexbox solution is a very easy way for modern browsers, so I recommend this for you:
.container {
display: flex;
align-items: center;
justify-content: center;
height: 100%;
background: green;
}
body,
html {
height: 100%;
}
<div class="container">
<div>Div to be aligned vertically</div>
</div>
Actually, you need two div's for vertical centering. The div containing the content must have a width and height.
#container {
position: absolute;
top: 50%;
margin-top: -200px;
/* Half of #content height */
left: 0;
width: 100%;
}
#content {
width: 624px;
margin-left: auto;
margin-right: auto;
height: 395px;
border: 1px solid #000000;
}
<div id="container">
<div id="content">
<h1>Centered div</h1>
</div>
</div>
Here is the result.
Edit 2020: only use this if you need to support old browsers like Internet Explorer 8 (which you should refuse to do 😉). If not, use Flexbox.
This is the simplest method I found and I use it all the time
(jsFiddle demo here).

</article>
</div>
Support starts with Internet Explorer 8.
After a lot of research I finally found the ultimate solution. It works even for floated elements. View Source
.element {
position: relative;
top: 50%;
transform: translateY(-50%); /* or try 50% */
}
Use the CSS Flexbox align-items property to achieve this.
html, body {
height: 100%;
}
body {
display: flex;
align-items: center;
}
<div>This is centered vertically</div>
To center the div on a page, check the fiddle link.
#vh {
margin: auto;
position: absolute;
top: 0;
left: 0;
bottom: 0;
right: 0;
}
.box{
border-radius: 15px;
box-shadow: 0 0 8px rgba(0, 0, 0, 0.4);
padding: 25px;
width: 100px;
height: 100px;
background: white;
}
<div id="vh" class="box">Div to be aligned vertically</div>
Another option is to use flex box, check the fiddle link.
.vh {
background-color: #ddd;
height: 400px;
align-items: center;
display: flex;
}
.vh > div {
width: 100%;
text-align: center;
vertical-align: middle;
}
<div class="vh">
<div>Div to be aligned vertically</div>
</div>
Another option is to use a CSS 3 transform:
#vh {
position: absolute;
top: 50%;
left: 50%;
/*transform: translateX(-50%) translateY(-50%);*/
transform: translate(-50%, -50%);
}
.box{
border-radius: 15px;
box-shadow: 0 0 8px rgba(0, 0, 0, 0.4);
padding: 25px;
width: 100px;
height: 100px;
background: white;
}
<div id="vh" class="box">Div to be aligned vertically</div>
The easiest solution is below:
.outer-div{
width: 100%;
height: 200px;
display: flex;
border:1px solid #000;
}
.inner-div{
margin: auto;
text-align: center;
border: 1px solid red;
}
<div class="outer-div">
<div class="inner-div">
Hey there!
</div>
</div>
There are multiple ways to achieve this.
Using flex property of CSS.
Solution #1
.parent {
width: 400px;
height:200px;
background: blue;
display: flex;
align-items: center;
justify-content:center;
}
.child {
width: 75px;
height: 75px;
background: yellow;
}
<div class="parent">
<div class="child"></div>
</div>
or by using display: flex; and margin: auto;
Solution #2
.parent {
width: 400px;
height:200px;
background: blue;
display: flex;
}
.child {
width: 75px;
height: 75px;
background: yellow;
margin:auto;
}
<div class="parent">
<div class="child"></div>
</div>
show text center
Solution #3
.parent {
width: 400px;
height: 200px;
background: yellow;
display: flex;
align-items: center;
justify-content:center;
}
<div class="parent">Center</div>
Using percentage(%) height and width.
Solution #4
.parent {
position: absolute;
height:100%;
width:100%;
background: blue;
display: flex;
align-items: center;
justify-content:center;
}
.child {
width: 75px;
height: 75px;
background: yellow;
}
<div class="parent">
<div class="child"></div>
</div>
Unfortunately — but not surprisingly — the solution is more complicated than one would wish it to be. Also unfortunately, you'll need to use additional divs around the div you want vertically centered.
For standards-compliant browsers like Mozilla, Opera, Safari, etc. you need to set the outer div to be displayed as a table and the inner div to be displayed as a table-cell — which can then be vertically centered. For Internet Explorer, you need to position the inner div absolutely within the outer div and then specify the top as 50%. The following pages explain this technique well and provide some code samples too:
Vertical Centering in CSS
Vertical Centering in CSS with Unknown Height (Internet Explorer 7 compatible) (Archived article courtesy of the Wayback Machine)
There is also a technique to do the vertical centering using JavaScript. Vertical alignment of content with JavaScript & CSS demonstrates it.
If someone cares for Internet Explorer 10 (and later) only, use Flexbox:
.parent {
width: 500px;
height: 500px;
background: yellow;
display: -webkit-flex;
display: -ms-flexbox;
display: flex;
-webkit-justify-content: center;
-ms-flex-pack: center;
justify-content: center;
-webkit-align-items: center;
-ms-flex-align: center;
align-items: center;
}
.centered {
width: 100px;
height: 100px;
background: blue;
}
<div class="parent">
<div class="centered"></div>
</div>
Flexbox support: http://caniuse.com/flexbox
A modern way to center an element vertically would be to use flexbox.
You need a parent to decide the height and a child to center.
The example below will center a div to the center within your browser. What's important (in my example) is to set height: 100% to body and html and then min-height: 100% to your container.
body, html {
background: #F5F5F5;
box-sizing: border-box;
height: 100%;
margin: 0;
}
#center_container {
align-items: center;
display: flex;
min-height: 100%;
}
#center {
background: white;
margin: 0 auto;
padding: 10px;
text-align: center;
width: 200px;
}
<div id='center_container'>
<div id='center'>I am center.</div>
</div>
.center {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%); /* (x, y) => position */
-ms-transform: translate(-50%, -50%); /* IE 9 */
-webkit-transform: translate(-50%, -50%); /* Chrome, Safari, Opera */
}
.vertical {
position: absolute;
top: 50%;
//left: 0;
transform: translate(0, -50%); /* (x, y) => position */
}
.horizontal {
position: absolute;
//top: 0;
left: 50%;
transform: translate(-50%, 0); /* (x, y) => position */
}
div {
padding: 1em;
background-color: grey;
color: white;
}
<body>
<div class="vertical">Vertically left</div>
<div class="horizontal">Horizontal top</div>
<div class="center">Vertically Horizontal</div>
</body>

Centering only vertically
If you don't care about Internet Explorer 6 and 7, you can use a technique that involves two containers.
The outer container:
should have display: table;
The inner container:
should have display: table-cell;
should have vertical-align: middle;
The content box:
should have display: inline-block;
You can add any content you want to the content box without caring about its width or height!
Demo:
body {
margin: 0;
}
.outer-container {
position: absolute;
display: table;
width: 100%; /* This could be ANY width */
height: 100%; /* This could be ANY height */
background: #ccc;
}
.inner-container {
display: table-cell;
vertical-align: middle;
}
.centered-content {
display: inline-block;
background: #fff;
padding: 20px;
border: 1px solid #000;
}
<div class="outer-container">
<div class="inner-container">
<div class="centered-content">
Malcolm in the Middle
</div>
</div>
</div>

Centering horizontally and vertically
If you want to center both horizontally and vertically, you also need the following.
The inner container:
should have text-align: center;
The content box:
should re-adjust the horizontal text-alignment to for example text-align: left; or text-align: right;, unless you want text to be centered
Demo:
body {
margin: 0;
}
.outer-container {
position: absolute;
display: table;
width: 100%; /* This could be ANY width */
height: 100%; /* This could be ANY height */
background: #ccc;
}
.inner-container {
display: table-cell;
vertical-align: middle;
text-align: center;
}
.centered-content {
display: inline-block;
text-align: left;
background: #fff;
padding: 20px;
border: 1px solid #000;
}
<div class="outer-container">
<div class="inner-container">
<div class="centered-content">
Malcolm in the Middle
</div>
</div>
</div>
See also this Fiddle!
It can be done in two ways
body{
left: 50%;
top:50%;
transform: translate(-50%, -50%);
height: 100%;
width: 100%;
}
OR
Using flex
body {
height:100%
width:100%
display: flex;
justify-content: center;
align-items: center;
}
align-items:center; makes the content vertically center
justify-content: center;makes the content horizontally center
This is always where I go when I have to come back to this issue.
For those who don't want to make the jump:
Specify the parent container as position:relative or position:absolute.
Specify a fixed height on the child container.
Set position:absolute and top:50% on the child container to move the top down to the middle of the parent.
Set margin-top:-yy where yy is half the height of the child container to offset the item up.
An example of this in code:
<style type="text/css">
#myoutercontainer {position:relative}
#myinnercontainer {position:absolute; top:50%; height:10em; margin-top:-5em}
</style>
...
<div id="myoutercontainer">
<div id="myinnercontainer">
<p>Hey look! I'm vertically centered!</p>
<p>How sweet is this?!</p>
</div>
</div>
I just wrote this CSS and to know more, please go through: This article with vertical align anything with just 3 lines of CSS.
.element {
position: relative;
top: 50%;
transform: perspective(1px) translateY(-50%);
}
For newcomers, please try:
display: flex;
align-items: center;
justify-content: center;
The three lines of code using transform works practically on modern browsers and Internet Explorer:
.element{
position: relative;
top: 50%;
transform: translateY(-50%);
-moz-transform: translateY(-50%);
-webkit-transform: translateY(-50%);
-ms-transform: translateY(-50%);
}
I am adding this answer since I found some incompleteness in the previous version of this answer (and Stack Overflow won't allow me to simply comment).
'position' relative messes up the styling if the current div is in the body and has no container div. However 'fixed' seems to work, but it obviously fixes the content in the center of the viewport
Also I used this styling for centering some overlay divs and found that in Mozilla all elements inside this transformed div had lost their bottom borders. Possibly a rendering issue. But adding just the minimal padding to some of them rendered it correctly. Chrome and Internet Explorer (surprisingly) rendered the boxes without any need for padding
CSS Grid
body, html { margin: 0; }
body {
display: grid;
min-height: 100vh;
align-items: center;
}
<div>Div to be aligned vertically</div>
.center{
display: grid;
place-items: center;
}
The answer from Billbad only works with a fixed width of the .inner div.
This solution works for a dynamic width by adding the attribute text-align: center to the .outer div.
.outer {
position: absolute;
display: table;
width: 100%;
height: 100%;
text-align: center;
}
.middle {
display: table-cell;
vertical-align: middle;
}
.inner {
text-align: center;
display: inline-block;
width: auto;
}
<div class="outer">
<div class="middle">
<div class="inner">
Content
</div>
</div>
</div>
Just do it: Add the class at your div:
.modal {
margin: auto;
position: absolute;
top: 0;
right: 0;
left: 0;
bottom: 0;
height: 240px;
}
And read this article for an explanation. Note: Height is necessary.
I did it with this (change width, height, margin-top and margin-left accordingly):
.wrapper {
width: 960px;
height: 590px;
position: absolute;
top: 50%;
left: 50%;
margin-top: -295px;
margin-left: -480px;
}
<div class="wrapper"> -- Content -- </div>
Not answering for browser compatibility but to also mention the new Grid and the not so new Flexbox feature.

I think a solid solution for all browsers without using Flexbox - "align-items: center;" is a combination of display: table and vertical-align: middle;.
CSS
.vertically-center
{
display: table;

Especially for parent divs with relative (unknown) height, the centering in the unknown solution works great for me. There are some really nice code examples in the article.
It was tested in Chrome, Firefox, Opera, and Internet Explorer.
/* This parent can be any width and height */
.block {
text-align: center;
}
/* The ghost, nudged to maintain perfect centering */
.block:before {
content: '';
display: inline-block;
height: 100%;
vertical-align: middle;
margin-right: -0.25em; /* Adjusts for spacing */
}
/* The element to be centered, can
also be of any width and height */
.centered {
display: inline-block;
vertical-align: middle;
width: 300px;
}
<div style="width: 400px; height: 200px;">
<div class="block" style="height: 90%; width: 100%">
<div class="centered">
<h1>Some text</h1>
<p>Any other text..."</p>
</div>
</div>
</div>
There is a trick I found out recently: You need to use top 50%, and then you do a translateY(-50%).
.outer-div {
position: relative;
height: 150px;
width: 150px;
background-color: red;
}
.centered-div {
position: absolute;
top: 50%;
-webkit-transform: translateY(-50%);
-ms-transform: translateY(-50%);
transform: translateY(-50%);
background-color: white;
}
<div class='outer-div'>
<div class='centered-div'>
Test text
</div>
</div>

Modal height resizes to content, but at max-height of modal content becomes scrollable

I have a modal that contains tabs that potentially will have long content.
What I'm trying to do is get the modal to resize on content height but when the content exceeds the modals max-height of 80% the content section should become scrollable.
currently, it works that content scrolls when it gets too large. but the problem is now the modal__content container stays 100% height regardless of the content. if I remove the height from modal__content then the content scroll no longer works.
Hope this makes sense
<div class="modal">
<div class="modal__container">
<div class="modal__content">
<div class="modal__left"></div>
<div class="modal__right>lorem 200 </div>
</div>
</div>
<div>
<div class="modal-overlay"></div>
CSS
html, body {
height: 100%;
}
*, ::after, ::before {
box-sizing: border-box;
}
.modal {
width: 100%;
height: 100%;
background: rgba(0,0,0,.7);
position: fixed;
left: 0;
top: 0;
}
.modal__container {
width: 1076px;
display: flex;
align-items: center;
height: calc(100% - 3.5rem);
margin:1.75rem auto;
}
.modal__content {
background: white;
display: flex;
height: 100%;
}
.modal__left {
width: 400px;
background: #f6f6f6;
}
.modal__right {
flex: 1;
display: flex;
align-items: center;
}
.modal__inner {
padding: 2.5rem;
}
.modal__body {
padding: 0 2.5rem;
height: calc(100% - 5rem);
overflow-y: scroll;
}
Try adding
overflow-y: scroll;
to .modal__content
You could also try switching the heights from
height: calc(100% - 3.5rem);
to
height: 100vh;

Make child div width 100% of container with overflow-x using Flexbox

I'm trying to make a child div of a Flexbox container with overflowing-x content have 100% of the width WITH the overflow, but I can't figure out it, have made several searches and couldn't find a solution;
Can someone help me?
Fiddle: https://codepen.io/joaovtrc/pen/MWaaxKr
HTML:
<div class="test-container">
<div class="test-item-overflow">
overflowing contenttttttt
</div>
<div class="test-item-2"></div>
</div>
CSS:
.test-container {
width: 1000px;
height: 500px;
margin: auto;
background: black;
display: flex;
flex-direction: column;
overflow-x: auto;
}
.test-item-overflow {
width: fit-content;
height: 55px;
background: red;
border: 1px solid yellow;
}
.test-item-2 {
width: 100%;
height: 55px;
background: blue;
border: 1px solid green;
}
I want the 'test-item-2' (the one with the blue background) div to match the red one in width, but, keep in mind that the content on the redbox might not be exactly the same everytime, so no calc(100% + x) with fixed params...
As you have set the width: fit-content; for the overflow div, it makes the width uncontrollable as it grows with more content in that div. one solution might be to change the width: 100%; and add overflow-x: scroll to the class .test-item-overflow. (see the change in the below snippet)
However, if you want to keep the width: fit-content; for the red div and change the blue div's width along with the red one (depending on the content) you can add: document.getElementsByClassName("test-item-2").style.width = document.getElementsByClassName("test-item-overflow").offsetWidth + "px". (in this case it's better to define id for the divs and use getElementById in the js code)
.test-container {
width: 1000px;
height: 500px;
margin: auto;
background: black;
display: flex;
flex-direction: column;
overflow-x: auto;
}
.test-item-overflow {
width: 100%;
overflow-x: scroll;
height: 55px;

aaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
</div>
<div class="test-item-2"></div>
</div>
So I really recommend you go ahead and add the following lines
Margin:0px;
This will take away all the space between your content and browser
Padding:0px;
This will take away all the space between your content and content border
Overflow:hidden;
Finally this should remove overflown content.
Hope that helped!
Better to use display:grid; on .test-container. After if you dont want to have gap between to the 2 cells, this is due to .test-container { height: 500px; }.
DEMO:
html body {
width: 100vw;
height: 100vh;
margin: 0px;
overflow: auto;
display: flex;
align-items: center;
background: grey;
}
.test-container {
width: 1000px;
height: 500px;
margin: auto;
background: black;
/*display: flex;
flex-direction: column;*/
display:grid;
overflow-x: auto;
}
.test-item-overflow {
width: 1500px;
height: 55px;
background: red;
border: 1px solid yellow;
}
.test-item-2 {
width: 100%;
height: 55px;
background: blue;
border: 1px solid green;
}
<div class="test-container">
<div class="test-item-overflow">
overflowing contenttttttt
</div>
<div class="test-item-2"></div>
</div>

Set height of div to 100% of remaining space under header

I have 2 divs:
A header div at the top of the page with a set height of 150px.
A container div sitting under the header div.
What I would like is for the container div to be dynamic and resize to 100% of the remaining space underneath the header div.
I have tried putting in height: 100% but this makes the page need to scroll. I presume it is making the div 100% of the browser height rather than 100% of the remaining body's height.
How can I make it so that the container div simply resizes its height to the remaining body space?
Please find the relevant code below:
body,
html {
margin: 0;
height: 100%;
}
#header {
width: 100%;
height: 150px;
background-color: #999999;
}
#container {
width: 760px;
height: 100%;
background-color: #CCCCCC;
margin: 0 auto;
}
<div id="header"></div>
<div id="container"></div>
You can simply do that by using some math with the calc() CSS function. Subtract 150px (the header size) from 100%. This is dynamically calculated.
body,
html {
margin: 0;
height: 100%;
}
#header {
width: 100%;
height: 150px;
background-color: #999999;
}
#container {
width: 760px;
height: calc(100% - 150px);
background-color: #CCCCCC;
margin: 0 auto;
}
Compatibility: calc() is supported in most modern browsers and IE 9 +
Example fiddle and snippet below:
body,
html {
margin: 0;
height: 100%;
}
#header {
width: 100%;
height: 150px;
background-color: #999999;
}
#container {
width: 760px;
height: calc(100% - 150px);
background-color: #CCCCCC;
margin: 0 auto;
}
<div id="header"></div>
<div id="container"></div>
I think the correct modern way to acomplish this without css hacks is with FlexBox, which as of the writting of this post is supported by all modern browsers. (you can check browser compatibility here)
It also gives you more flexibility. If you later decide to add new rows (or even side columns) is very easy to acomplish without any calculations.
html,
body {
width: 100%;
height: 100%;
padding: 0;
margin: 0;
}
#container {
display: flex; /* Activates FlexBox Model */
flex-direction: column; /* Divs are spanned vertically */
width: 100%;
height: 100%;
}
#header {
background-color: #ccc;
height: 150px;
}
#content {
background-color: #888;
flex-grow: 1;
}
<div id="container">
<div id="header">My header with some stuff</div>
<div id="content">My content</div>
</div>
The outer container has to have position: relative and the div that you want to stretch to the bottom has to have position: absolute. This solution is pure css with no calls to calc().
body, html {
margin: 0;
height: 100%;
}
#container {
position: relative;
width: 100%;
height: 100%;
}
#header {
height: 150px;
width: 100%;
background-color: #999999;
}
#mainContent {
width: 760px;
top: 150px;
bottom: 0;
right: 0;
left: 0;
background-color: #CCCCCC;
margin: 0 auto;
position: absolute;
}

Issues creating 100% height divs using display: table-cell in Firefox

I am trying to create a two-column, full-screen magazine viewer, with a fixed width banner on the left. The right column will be responsive.
Utilising the display:table; method I have created the following:
http://jsfiddle.net/pouncebounce/pTeBP/2/
HTML
<div class="tbl_con">
<div class="tbl_row">
<div class="tbl_cell" id="banner">
</div>
<div class="tbl_cell" id="publication">
</div>
</div>
</div>
<script>
var viewer = new com.zmags.api.Viewer();
viewer.setPublicationID("b129d2b8");
viewer.setParentElementID("publication");
viewer.show();
</script>
CSS
* {
margin: 0;
padding: 0;
border: none;
}
html, body {
height: 100%;
width: 100%;
overflow: hidden;
}
.tbl_con {
display: table;
width: 100%;
min-height: 100%;
*height: 100%;
}
.tbl_row {
display: table-row;
width: 100%;
min-height: 100%;
*height: 100%;
}
.tbl_cell {
display: table-cell;
min-height: 100%;
*height: 100%;
}
#banner {
width: 200px;
background-color: #1E90FF;
border-right: solid 3px #fff;
}
#publication {
width: *;
background-color: #FFAB1E;
}
This displays correctly in the latest version of IE and Chrome, but not in Firefox, where the 100% heights, or the actual magazine, do not appear at all. Any reason why?
Change *height to height and remove min-height.
Make sure you test in IE7, but it should work.
