Image:
I have a container div (yellow) which I’d like to keep at 50% width of the window. A child of that container is an image div (purple) that stretches to 100% of the parent container’s width. and there’s a sticky label (pink) on top of the image div (position: absolute so it can be offset relatively to the image). I'd like to keep that entire half of the screen fixed positioning so it stays sticky as I scroll.
There’s also a title under the image, and that title needs to be visible no matter if someone shrinks the window vertically. So in that scenario the image div should shrink vertically, if needed, in order for that title to be shown.
Basically I'm trying to have the image div always be 100% width of the parent container div. With the image div having a max % height so it can shrink vertically. Or have it keep a fixed aspect ratio (3:4 or whatever) when it shrinks vertically.
I'm trying to avoid using fixed pixels, or ems, in the entirety of my CSS. since the website needs to be stretchy/‘fluid’ vertically, because that title under the image has to show.
HTML looks roughly like:
<wrapper>
<left-column>
<normal text and scrollable stuff>
<right-column-yellow>
<image sticky label-pink>
<image div-purple>
<image title>
Sorry if this is damn confusing my brain is fried! Can anyone pls help me?
You can divide your left and right panel by using position fixed.
If I'm not wrong with your description, this is the answer.
<div class="wrapper">
<div class="left">
<p><!--Some very long text--></p>
</div>
<div class="right">
<div class="image">
<div class="label">Label</div>
<div class="title">Title</div>
</div>
</div>
Some CSS
.left,.right{
position: fixed;
width: 50%;
height: 100%;
display: inline-block;
}
.left{
left:0;
top: 0;
overflow: auto;
}
.right{
right: 0;
top:0;
background-color: yellow;
}
.right .image{
position: relative;
width: 100%;
height: 50%;
top: 50%;
left: 0;
background-color: #fff;
transform: translateY(-50%);
}
.right .image .label{
position: absolute;
left: 0;
right: 0;
top: -10px;
text-align: center;
width: 200px;
background-color: pink;
margin: auto;
}
.right .image .title{
position: absolute;
left: 0;
right: 0;
bottom: -40px;
text-align: center;
width: 200px;
background-color: #000;
margin: auto;
color: #fff;
font-size: 30px;
}

I have this HTML structure:
<div class="container">
<img class="image" />
<div class="overlay">
<div class="insides">more elements here</div>
</div>
</div>
and this CSS code:
.container {
position: relative;
height: 88vh;
margin: 0;
}
.image {
height: 100%;
position: absolute;
margin-right: auto;
margin-left: auto;
left: 0;
top: 0;
bottom: 0;
right: 0;
}
.overlay {
position: absolute;
}
My requirements are as follows:
Make image fill the available vertical space and center it horizontally. (Works)
Make image overlay of the same size as the image - without using an absolute width attribute. (Does not work - problem)
Fix icons to specific spots on the image. (Using percentages for top and left attributes ... Not sure if this is going to be as easy as I currently think.)
How can I have it all - a horizontally centered image expanded to fill the vertical space, an exact overlay and elements fixed to specific spot of the image?
While I would prefer a CSS hack, a Javascript solution will be considered, too, in case the width of the image needs to be transferred to the overlay programmatically.
One way of doing it would be to wrap the Image and the Overlay in a div and center that.
.container {
position: relative;
height: 88vh;
margin: 0;
text-align: center;
}
.imagecontainer
{
position: relative;
display: inline-block;
height: 100%;
}
.image {
height: 100%;
}
.overlay {
position: absolute;
top: 0px;
left: 0px;
right: 0px;
bottom: 0px;
}
<div class="container">
<div class='imagecontainer'>
<img class="image" src='imageurlhere'/>
<div class="overlay">
<div class="insides">more elements here</div>
</div>
</div>
</div>
Like this, the Image will set the width of its parent and in doing so also the width of the Overlay.
I was wondering if you can help me with this.
I have a div (in white) where I need to put two circular buttons (in green) on the borders. Everything should be done with CSS.
It should look like this:
Screenshot
Now, the thing is that I don't know the size of the white div, and I won't know it at the time of creation, because it will get added to the DOM afterwards. All I know is that the white div has a percentage width and height relative to its future parent. So, at the time of creation, since it's not yet added, any calls to width(), height() or its css values won't work.
I've seen all those snippets that tell you how to make a div with a fixed aspect ratio. I need this now, I need the button to be 1:1, but all I know about the dimensions, is that it has to be 100% of the height of the white div (and therefore, its width should be equal as its height). All the examples I've seen assume that you know the width and to make the height keep the ratio. In my case, what I know is the height (100%) and I want the width to adapt.
I have no idea how to achieve this.
This is my snippet:
body{
background-color: #DCDCDC;
}
.container {
width: 50%;
height: 7%;
background: white;
border-radius: 20px;
position: absolute;
}
.arrow {
background: green;
border-radius: 20px;
height: 100%;
position: absolute;
}
.arrow:after{
content: "";
display: block;
padding-right: 100%;
}
.arrow:last-child {
right: 0;
}
<div class="container">
<div class="arrow"></div>
<div class="arrow"></div>
</div>
https://jsfiddle.net/7bxecL9m/
If you know how can I do this without entering any fixed value (jQuery use is of course valid), I'd really appreciate it.
Thanks.
There are many variables here:
Since container's height is % and circle radius is px units, one is static and the other one will resize.
The only way to preserve 1:1 with just html/css, considering the container's height % will resize circle's height as well, would be to isolate circle's div width & height to something static like px units.
Now, since you said no fixed dimensions, the only thing I can think of is to comment .arrow's 100% height, to prevent resizing other than 1:1, and nesting a div inside .arrow to restrain 1:1 with static units (ideally impacting .arrow directly would be less code but if you don't want/can't set them on that element, maybe you consider this).
If you want the circle to remain circular as the content expands, you need to dynamically adjust the height to match the width. You could use Javascript to achieve this, but your border-radius is tied to container's in px static units, since container will always be bigger something like border-radius: 50% wouldn't work for both, 50% radius of circle would never match 50% of container's (that is, if you care about radius alignment).
body {
background-color: #DCDCDC;
}
body,
html {
height: 100%;
}
.container {
width: 50%;
height: 37%;
background: white;
border-radius: 20px;
position: relative;
}
.arrow {
background: green;
border-radius: 20px;
/*height: 100%;*/
position: absolute;
overflow: hidden;
}
.bLimit {
height: 40px;
width: 40px;
line-height: 40px;
}
.arrow:after {
content: "";
display: block;
padding-right: 100%;
}
.arrow:last-child {
right: 0;
}
<div class="container">
<div class="arrow">
<div class="bLimit">button overflow</div>
</div>
<div class="arrow">
<div class="bLimit">button</div>
</div>
</div>
Why not doing a fixed width in percent for your arrow :
.arrow {
background: green;
border-radius: 20px;
height: 100%;
position: absolute;
width: 10%;
}
body{
background-color: #DCDCDC;
}
.container {
width: 50%;
height: 7%;
background: white;
border-radius: 20px;
position: absolute;
}
.container:after,.container:before{
content: " ";
display: block;
padding: 4%;
z-index: 999;
top: 0;
position:absolute;
background: green;
border-radius: 50%;
}
.container:before {
left: 0;
}
.container:after{
right: 0;
}
<div class="container">
</div>
You can achieve using before and after CSS pseudo selectors. You check this Example.
There is a posibility to get this result using a image (that won't show) of the required ratio.
In this case, the ratio is 1:1 so we will use an image of 50px (but it can be any size)
.container {
width: 300px;
height: 20px;
border: solid 1px blue;
margin: 40px;
position: relative;
}
.container:nth-child(2) {
height: 40px;
}
.container:nth-child(3) {
height: 60px;
}
.arrow {
height: 100%;
background-color: red;
opacity: 0.5;
position: absolute;
border-radius: 50%;
transform: translateX(-50%);
}
.arrow:last-child {
right: 0px;
transform: translateX(50%);
}
img {
height: 100%;
opacity: 0;
}
<div class="container">

I am trying to overlay 2 DIV's in my main parent DIV:
I want to overlay the the second div over on top of the first one. I have a problem overlaying it as I cannot keep it in the middle of the screen.
I have tried this to overlay:
The overlay works fine here, but my container is no longer center when I do this. How can I overlay and keep it center ?
div {
border: 5px solid red;
}
#first {
position: absolute;
z-index: 1;
border-color: orange;
}
#second {
position: absolute;
z-index: 2;
border-color: green;
}
<div id="container" class="container text-center">
<div id="first">Hi</div>
<div id="second">Hello</div>
</div>
Here is what you need to do (see width of both divs and text-align properties):
You can give them background color to see z-index works perfectly :)
#first {
text-align: center;
height: 300px;
width: 100%;
position: absolute;
z-index: 1;
}
#second {
text-align: center;
height: 300px;
width: 100%;
position: absolute;
z-index: 2;
}
<div id="container" class="container text-center">
<div id="first">Hi</div>
<div id="second">Hello</div>
</div>
When you position absolute, the positioned element is taken out of the document flow and positioned relative to the next highest parent element that is not the default position, i.e. not position: static;
The following will cause the absolute positioned children to stay within the containing div:
#container {
position: relative;
}
Your container's text is no longer centered because you have removed its children from the document flow. In essence, it has no content and collapses, and therefore, has no width to which to align the text.
One thing you could do is set the container to position: relative and full-width (i.e. width: 100vw), then set its children to width: 100%.
Then the inner divs will take on the width of their parent.
See this working JSFiddle.
#container {
position: relative;
width: 100%;
height: 100px;
background-color: yellow;
display: flex;
justify-content: center;
align-items: center;
}
#first{
position: absolute;
}
#second{
position: absolute;
}
<div id="container" class="container">
<div id="first">Hi</div>
<div id="second">Hello</div>
</div>
Your main issue is that the divs will not have any relative width to the parent div.
Therefore the text is still technically "centered" in each corresponding div because they're inheriting text-align: center from the container div.
However, the divs' widths will automatically be as wide as they needs to be (i.e. to fit the text, in this case).
You can remedy this one of two ways:
Force the divs to be centered
Give both divs the following (extra) CSS:
left: 50%;
width: 100%;
margin-left: -50%;
This will literally center them in their parent div.
or
Force the divs to be the same size as their parent
Give both the divs the following (extra) CSS:
top: 0;
bottom: 0;
left: 0;
right: 0;
This sets the divs to span their entire parent's height and width.
In both situations, you might need to make the .container class use position: relative, in order for the child divs to have something to be absolute to.
If you're using Bootstrap, there is no need to worry about this, as .container class already has this applied.
Hope one of these solutions helps you :)
Try this style:
#first,
#second {
left: 50%;
transform: translate(-50%, 0);
}
div {
border: 5px solid red;
}
#first {
position: absolute;
z-index: 1;
border-color: orange;
}
#second {
position: absolute;
z-index: 2;
border-color: green;
}
#first,
#second {
left: 50%;
transform: translate(-50%, 0);
}
<div id="container" class="container text-center">
<div id="first">Hi</div>
<div id="second">Hello</div>
</div>
My Goal:
So I am making a webpage with a map of the USA as the "background image" and on top of that map I have about 10 markers pointing to specific location. The markers are NOT part of the picture thats just me adding them with absolute positioning and top and left with a percentage.
The Problem:
As I scale down the page or scroll up and down the markers that I have set with absolute positioning begin to move out of the spot they are suppose to be on because the background-image is getting smaller do to it displaying 100%.
The Question:
How can I achieve what I want with the markers on the map where they are suppose to be not moving as the window is being scaled down?
Now I know of only 1 solution and this solution can take a VERY LONG TIME. What I was thinking is instead of positioning the markers that I want on the map with percentage I can do it with pixels and then use a TON of media queries and keep on adjusting it. Not only is this solution going to take extremely long but it also does not seems like the correct way to go about this.
HTML:
<div class="container main-content"><!--the map background image is set here-->
<div class="row relative">
<div class="eq-content-wrap">
<div class="eq-content">
<div class="marker"></div> <!--the marker that is positioned absolute-->
</div>
</div>
</div>
CSS:
html, body{
width: 100%;
height: 100%;
margin: 0px;
padding: 0px;
background: #000;
}
body{ overflow: hidden; }
.main-content{
background: url('assets/img/map1.jpg') no-repeat top center;
background-size: contain;
height: 100% !important;
width: 100% !important;
}
.eq-content-wrap{
position: absolute;
width: 500px !important;
top: 22%;
left: 40%;
}
.marker{
height: 40px;
width: 40px;
border-radius: 100%;
background-color: red;
position: absolute;
top: 50%;
margin-top: -20px;
}
The problem is that your background image's size is set to 100%: background-size: 100%. This means that when the browser tries to scale the content, the background does not scale with it (it stays 100%).
Your best bet is to remove the background-size property completely. This allows the markers to stay in place when the page scales, however, you won't get the full-screen background effect that you currently have (unless you have a larger image).
The background will still move, however, once the browser window width is less than the image's width. This is because you have the background-position set to top center. The center is what causes it to move once the browser window width is less than the image width. Change center to left and it will fix that issue. You'll also need to set the marker's container to be based to the left as well for this to work on wider screens though. Basically, removing all center properties would help, but the screen wouldn't be centered on a wide screen.
Try substituting css :before pseudo element for .marker ; set percentage unit values utilizing calc()
html,
body {
width: 100%;
height: 100%;
margin: 0px;
padding: 0px;
background: #000;
}
body {
overflow: hidden;
}
.main-content {
background: url(http://lorempixel.com/400/300) no-repeat top center;
background-size: contain;
height: 100% !important;
width: 100% !important;
}
.eq-content-wrap {
position: absolute;
width: 500px !important;
top: 22%;
left: 40%;
}
.main-content:before {
content: " ";
height: calc(12.5%);
width: calc(5%);
border-radius: 100%;
background-color: red;
position: absolute;
top: calc(50%);
left: calc(50%);
margin-top: calc(1%);
}
<div class="container main-content">
<!--the map background image is set here-->
<div class="row relative">
<div class="eq-content-wrap">
<div class="eq-content">
<div class="marker"></div>
<!--the marker that is positioned absolute-->

I want to display a horizontal stripe on image to vertical align.
this is my code
Html
<div class="demobox" id="demo-5">
<img src="Untitled-1000x288.jpg" />
<div class="details">

#demo-5 {
position: relative;
}
.demobox {

#demo-5:hover .details {
margin-left: 0;

margin-left: -1200px;
opacity: 0.7;
filter:alpha(opacity=70);
position: absolute;
top: 0;

.details {
background: none repeat scroll 0 0 #000000;
color: #FF0000;
height: 50px;
margin-top: 119px;
text-align: center;
width: 735px;
}
Now problem is images are not with fixed height & width.And i want to display horizontal
stripe in middle, how can i ?
will greatly appreciate your help !!
You need to set container's css position to relative and absolutelly position the title of the image inside the container.
The trick is in usage of percentage vertical positioning and subtracting half of stripes height via margin-top.
Quick example on jsfiddle.
Edit: I badly read the question... here is the corrected answer :-)
