Make a div inside Div - in the middle - javascript

I am trying to make a div inside another one exactly in the middle. Is there any better way to do that?
body, html
{
margin:0;
height:100%;
}
#master_wrapper
{
width:100px;
height:100px;
background:#57a957;
}
#header
{
left:50%;
width:50%;
height:50%;
background:red;
}
<div id="master_wrapper">
<div id="header">
Header
</div>

You can make the inner div exactly in the middle by adding style "margin: 0px auto" to the #header in the css file.

Just so you know, a lot of your css is pointless/redundant since you've not set your positioning of your classes. I.e. to use top:... left:... right:... and/or bottom:... you need to have set your positioning to absolute;
The snippet below allows you to horizontally and/or vertically center your div element:
html,
body {
padding: 0;
margin: 0;
}
#master_wrapper {
width: 100px;
height: 100px;
background: #57a957;
position: relative;
}
#header {
position: absolute;
width: 50%;
height: 50%;
background: red;
margin:0 auto; /*horizontally center*/
left:0;
right:0;
-webkit-transform: translateY(50%); /*vertically center*/
-ms-transform: translateY(50%);
transform: translateY(50%);
}
<div id="master_wrapper">
<div id="header">
Header
</div>

An example how to place a HTML Element in the middle horizontal and vertical
<!DOCTYPE html>
<html>
<head>
<title>Div in middle</title>
</head>
<body>
<div style="
background: red;
width : 300px;
height : 100px;
">
<div style="
background : #fff;
width : 123px;
height : 67px;
margin : 0 auto;
position: relative;
top : 50%;
transform : translateY(-50%);
">
Div in middle of other div
</div>
</div>
</body>
</html>
You can test in live editor if you want

margin: 0 auto;
This will automatically horizontally center your div with top and bottom margin of 0; You can also do:
margin: 0 auto 0 auto;
In order to control top and bottom margins, margin values go like:
margin: top right bottom left;

width: 100%; // can be in pixels also.
margin: 0 auto;

Try with padding: http://jsfiddle.net/5oxg9aay/1/
body, html {
margin: 0;
height: 100%;
}
#master_wrapper {
width: 58px;
height: 58px;
background: #57a957;
padding: 4%;
}
#header {
background: red;
width: 100%;
height: 100%;
}
or use a position: absolute; in the header and work with left/right/top/bottom but you need to make #master_wrapper the mother container for #header.

How can i make a box with 940px width fixed inside a scrollable div?

I'm trying to make a fixed box with 980px width and 500px height scrolling inside a div with 100% width and 1500px height, but it is not working at all.
That's what I did: https://jsfiddle.net/zjuyuhmz/2/embedded/result/
The box is moving when the page scrolls, and I want to make scroll only if the mouse is inside of the div.
Is this possible??
Html:
<div id="wrapper">
<div class="main">
<div class="container">
<div class="container2">
<div class="test"></div>
<div class="test"></div>
<div class="test"></div>
</div>
</div>
</div>
</div>
Css:
#wrapper {
position: relative;
width: 100%;
height: 100%;
color: #a3265e;
font-family: 'GillSans-SemiBold';
}
.main {
border: 1px solid red;
position: relative;
width: 100%;
height: 100%;
margin: 0 auto;
padding-top: 380px;
}
.container {
border: 1px solid green;
position: relative;
width: 100%;
height: 500px;
margin: 0 auto;
overflow: scroll;
}
.container2 {
height: 1500px;
margin: 0 auto;
}
.test {
width: 940px;
height: 500px;
position: fixed;
left: 50%;
margin-left: -480px;
background: black;
}
You need to write javascript code, where you can get cursor position and depending on that enable scroll event.
Replace the css for .test for this:
.test {
width: 940px;
height: 500px;
position: absolute;
left: 50%;
margin-left: -480px;
background: black;
}
.test:focus {
position:fixed;
}
This means: when the element with id "test" has the focus on, make it's position fixed. If not, make it's position absolute.

Horizontally and vertically align image in div

I'm using Bootstrap and WordPress.
I've been researching how to horizontally and vertically align an image inside a div (classic problem, apparently). I used the answer to this question to vertically align my image: How to vertically align an image inside div
Now I need to horizontally align it. I know to do that, you normally add margin: 0 auto;
The problem is that the method that I followed uses margin:auto; and it undos the vertical align if I change it to margin:0 auto;
I started to make a JSFiddle of the problem, but I couldn't replicate it. So I think it's something in Bootstrap that is overriding it, but I'm not sure what.
Here is the basic code I'm using from the vertical align solution on the other stackoverflow question:
HTML
<div class="crop-featured-2">
<img src="image.png">
</div>
CSS
.container {
position: relative;
width: 100%;
overflow: hidden;
}
.crop-featured-2 {
height: 100px;
width: 200px;
position: relative;
border: 1px solid red;
padding: 5px;
display:block;
}
.crop-featured-2 img {
min-height: 100px;
width:100%;
position: absolute;
top: 0;
bottom: 0;
left: 0;
right: 0;
margin: auto;
border:0px;
padding:0;
}
You can see the problem at http://ucaftercruz.com/upcoming/?page_id=30. It's the slider at the top and the problem is in the .carousel-inner div. Resize the browser to around 800px wide to be able to really see the issue.
Thanks so much in advance!
I had a look at your web page. I think the issue solves it self if you just remove the width rule from this selector:
.crop-featured-2 {
height: 320px;
width: 575px;
position: relative;
}
instead use
.crop-featured-2 {
height: 320px;
position: relative;
}
Try this
.crop-featured-2 {
position: relative;
margin: 0;
position: absolute;
top: 50%;
left: 50%;
margin-right: -50%;
transform: translate(-50%, -50%);
}

3 column layout with header and footer in center column

I am trying to make my page look like the Facebook Android app. The app can be summarized as having a 3 column layout with only the central column having the header (there is no footer, but in my requirement I also need a footer).
This can be shown in the image below
The red and blue div's are the left and right side-bars. The green and purple div's are the center div. The purple div's are the header and footer div's and would be sticking to the top and bottom of the page respectively.
One more requirement is there will be buttons on the header (top purple) to hide and show the left and right sidebars. Initially only the center div will be visible and the rest can be called into view as and when required. Here is my code till now. (I am not able to get the width for the center div)
HTML Code
<html>
<head>
<title>Sample</title>
<link rel="stylesheet" href="index.css" type="text/css" />
</head>
<body>
<div id="main">
<div id="leftBar" class="main">Left Bar</div>
<div id="content" class="inner">
<div id="header">Head</div>
<div id="body">Body</div>
<div id="footer">Footer</div>
</div>
<div id="rightBar" class="main">Right Bar</div>
</div>
</body>
</html>
CSS
body{
margin: 0px;
}
div.inner{
height: 500px;
width: 50%;
background: red;
}
div.main{
background: lime;
height: 200px;
overflow: hidden;
position: relative;
}
#leftBar{
float: left;
}
#content{
position: relative;
height: 100%;
float: left;
}
#rightBar{
float: right;
}
#header{
position: fixed;
top: 0px;
background: blue;
}
#body{
margin-top: 40px;
position: relative;
}
#footer{
position: absolute;
bottom: 0px;
}
I have also added the JavaScript code in the fiddle linked below
http://jsfiddle.net/mv6Bj/1/
The width should be such that the center div is full 100% width of the screen and when the right/left toggles come into the picture they should come to their position and push the center div to the left or right respectively. This is as per the standard Facebook app functionality.
These are the issues I am getting right now
The center div is not 100% and neither does it scale as elements appear and disappear
The height of the center div is not 100% (it is on Chrome, but strangely it is not on JSFiddle)
When I click on left, the leftBar disappears and the content div moves to the left but the header div remains where it is.
As per my understanding, I have updated the fiddle.
Working Demo
I have used display:table propery. You can refer this or this
html, body {
margin: 0px;
min-height:100%;
height:100%;
}
#main {
min-height:100%;
display:table;
width:100%;
height:100%;
}
#leftBar, #rightBar {
background: lime;
width:100px;
display:table-cell;
}
#content {
min-height: 100%;
display:table-cell;
background: red;
}
#header {
background: blue;
height:10%;
}
#body {
min-height:80%;
overflow:hidden;
}
#footer {
background: magenta;
height:10%;
}
Hope this works for you.

Pop up div shinks on browser resize

I have a popup which will get shrink and the content will dislocate on the browser window resize. I am stuck with this
Here is the fiddle: http://jsfiddle.net/sarathsprakash/ZjdU4/
and here is the fullscreen fiddle: http://jsfiddle.net/sarathsprakash/ZjdU4/show/
Maybe you could view and check resizing the window
HTML
<div id="popup" >
<div id="img-section" >
<img src="http://icons.iconarchive.com/icons/artdesigner/tweet-my-web/256/single-bird-icon.png" />
</div>
<div id="description">
//text content
</div>
</div>
<div id="fade" class="black_overlay"></div>
click here
CSS
.black_overlay {
display: none;
position: absolute;
top: 0%;
left: 0%;
min-width: 100%;
min-height: 100%;
background-color: black;
z-index:1001;
-moz-opacity: 0.8;
opacity:.80;
filter: alpha(opacity=80);
}
#popup {
display: none;
position: fixed;
top: 8%;

max-width:1200px;
max-height:600px;
height:auto;
width:auto;
padding: 16px;
background-color: white;
z-index:1002;
overflow:hidden;
}
#img-section {
position:relative;
width:800px;
float:left;
background:black;
cursor:pointer;
height:600px;
padding:5px;
margin-top: -20px;
margin-left: -15px;
margin-right: 10px;
}
#description {
position:relative;
background-color: #fff;
max-width:400px;
overflow-y: auto;
position: relative;
word-wrap: break-word;
max-height:600px;
height:auto;
padding: 20px;
}
#img-section > img {
display:inline-block;
height: auto;
vertical-align:middle;
width:auto;
}
I want the poup to remain as it is, It should not shrink
Thanks in advance
Side scrolling for a popup is horrible, but:
make the popup position: absolute instead of fixed
give the body a min-width of left margin + popup width (currently that would be calc(1200px + 10%)
same for height?
make all max-width => width, because you know how much room you have
Your existing CSS is mighty strange, but this might do it: http://jsfiddle.net/rudiedirkx/ZjdU4/1/
Highlights:
body {
min-width: calc(1200px + 10%);
}
.black_overlay {
position: fixed;
top: 0;
left: 0;
right: 0;
bottom: 0;
}
#popup, #popup * {
box-sizing: border-box;
}
#popup {
position: absolute;
width: 1200px;
height: 600px;
padding: 0;
}
You are using percentage for your height and width.
The browser change its size on Resize, therefore the value of the percentage depreciates.
Like 10% of 100px differs from 10% of 10px.
Use px to keep your height and width the same size on resize.
Of course depending on what you want neither is better than the other

How can I make a div auto-adjust its height between two divs, according to window height using CSS/Javascript?

I have a div positioned at the top of the body and another div positioned at the bottom of the body
Now I want to place a div between those two divs and have its height take the max space available between those two divs.
The vertical space between those two divs is not fixed, meaning that when the user decreases/increases the height of the window, I want the middle div to readjust its height accordingly.
More specifically :
<body>
<div style="position: fixed; top: 0px; left: 0px; width: 200px; height: 100%;">
<div style="float: left; height: 50px, width: 200px; background-color: green;"/>
<div style="float: left; height: ???? ; width: 200px; background-color: red;"/>
<div style="float: left; height: 50px, width: 200px; background-color: blue;" />
</div>
</body>
So basically imagine a green rectangular fixed at the top left of the page, a blue one fixed at the bottom left of the page and a red column between them readjusting its height according to the height of the window.
How can I achieve this?
Setting its height at 100% simply makes the middle div expand its height to the bottom of the window which is not what I want. I need it to stop where the blue div starts. Also, making its height e.g. 73% doesn't make it auto-adjust itself correctly when the window height is changed either.
Assuming you are doing this because you want a footer that is flushed to the bottom of the page, then this will achieve a similar effect: http://matthewjamestaylor.com/blog/keeping-footers-at-the-bottom-of-the-page
However solution does not resize the middle div but merely positions the footer over it and then use padding to prevent the contents of the middle div from going onto the footer.
If you want to actually change the size of the middle div, here's the JavaScript for it using jQuery: http://jsfiddle.net/BnJxE/
JavaScript
var minHeight = 30; // Define a minimum height for the middle div
var resizeMiddle = function() {
var h = $('body').height() - $('#header').height() - $('#footer').height();
h = h > minHeight ? h : minHeight;
$('#body').height(h);
}
$(document).ready(resizeMiddle);
$(window).resize(resizeMiddle);
HTML
<div id="container">
<div id="header"></div>
<div id="body"></div>
<div id="footer"></div>
</div>
CSS
html,
body {
margin:0;
padding:0;
height: 100%;
}
#header {
background:#ff0;
height: 100px;
}
#body {
background: #aaa;
}
#footer {
height: 60px;
background:#6cf;
}
The correct way of ending <div> tag is by using </div>.
Try this code-
<body>
<div style="position: fixed; top: 0px; left: 0px; width: 200px; height: 100%;">
<div style="float: left; height: 50px; width: 200px; background-color: green; position: fixed;"></div>
<div style="float: left; height: 100%; width: 200px; background-color: red;"></div>
<div style="float: left; bottom: 0px; left:0px; position: fixed; height: 50px; width: 200px; background-color: blue;"></div>
</div>
</body>
HTML:
<body>
<div id="wrapper">
<div id="div1">...</div>
<div id="div2">...</div>
<div id="div3">
content<br/>
content<br/>
</div>
</div>
</body>
CSS:
html, body {
height:100%;
}
#wrapper {
position:relative;
height:100%;
}
#div3 {
background:pink;
bottom:0;
position:absolute;
width:100%;
}

You can use paddings the same height of your top and bottom elements and set box-sizing to border-box. By setting the height to 100% it will cover the entire height minus the paddings.

#container {
position: fixed;
