I want to position a <div>
(or a <table>
) element at the center of the screen irrespective of screen size. In other words, the space left on 'top' and 'bottom' should be equal and space left on 'right' and 'left' sides should be equal. I would like to accomplish this with only CSS.
I have tried the following but it is not working:
<body>
<div style="top:0px; border:1px solid red;">
<table border="1" align="center">
<tr height="100%">
<td height="100%" width="100%" valign="middle" align="center">
We are launching soon!
</td>
</tr>
</table>
</div>
</body>
Note:
It is either way fine if the <div>
element (or <table>
) scrolls with the website or not. Just want it to be centered when the page loads.

Alternative solution that doesn't use position absolute:
I see a lot of position absolute answers. I couldn't use position absolute without breaking something else. So for those that couldn't as well, here is what I did:
https://stackoverflow.com/a/58622840/6546317 (posted in response to another question).
The solution only focuses on vertically centering because my children elements were already horizontally centered but same could be applied if you couldn't horizontally center them in another way.
I would do this in CSS:
div.centered {
position: fixed;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}
then in HTML:
<div class="centered"></div>
It will work for any object. Even if you don't know the size:
.centered {
position: fixed;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}
Use flex. Much simpler and will work regardless of your div
size:
.center-screen {_x000D_
display: flex;_x000D_
flex-direction: column;_x000D_
justify-content: center;_x000D_
align-items: center;_x000D_
text-align: center;_x000D_
min-height: 100vh;_x000D_
}
_x000D_
<html>_x000D_
<head>_x000D_
</head>_x000D_
<body>_x000D_
<div class="center-screen">_x000D_
I'm in the center_x000D_
</div>_x000D_
</body>_x000D_
</html>
_x000D_
Set the width and height and you're good.
div {
position: absolute;
margin: auto;
top: 0;
right: 0;
bottom: 0;
left: 0;
width: 200px;
height: 200px;
}
If you want the element dimensions to be flexible (and don't care about legacy browsers), go with XwipeoutX's answer.
If you have a fixed div
just absolute position it at 50% from the top and 50% left and negative margin top and left of half the height and width respectively. Adjust to your needs:
div {
position: absolute;
top: 50%;
left: 50%;
width: 500px;
height: 300px;
margin-left: -250px;
margin-top: -150px;
}
Now, is more easy with HTML 5 and CSS 3:
<!DOCTYPE html>
<html>
<head>
<title>TODO supply a title</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<style>
body > div {
position: absolute;
top: 0;
bottom: 0;
left: 0;
right: 0;
display: flex;
justify-content: space-around;
align-items: center;
flex-wrap: wrap;
}
</style>
</head>
<body>
<div>
<div>TODO write content</div>
</div>
</body>
</html>
Another easy flexible approach to display block at center: using native text alignment with line-height
and text-align
.
Solution:
.parent {
line-height: 100vh;
text-align: center;
}
.child {
display: inline-block;
vertical-align: middle;
line-height: 100%;
}
And html sample:
<div class="parent">
<div class="child">My center block</div>
</div>
We make div.parent
fullscreen, and his single child div.child
align as text with display: inline-block
.
Advantages:
Simple example on JSFiddle: https://jsfiddle.net/k9u6ma8g
try this:
width:360px;
height:360px;
top: 50%; left: 50%;
margin-top: -160px; /* ( ( width / 2 ) * -1 ) */
margin-left: -160px; /* ( ( height / 2 ) * -1 ) */
position:absolute;
If there are anyone looking for a solution,
I found this,
Its the best solution i found yet!
div {
width: 100px;
height: 100px;
background-color: red;
position: absolute;
top:0;
bottom: 0;
left: 0;
right: 0;
margin: auto;
}

Hope you enjoy!
try this
<table style="height: 100%; left: 0; position: absolute; text-align: center; width: 100%;">
<tr>
<td>
<div style="text-align: left; display: inline-block;">
Your Html code Here
</div>
</td>
</tr>
</table>
Or this
<div style="height: 100%; left: 0; position: absolute; text-align: center; width: 100%; display: table">
<div style="display: table-row">
<div style="display: table-cell; vertical-align:middle;">
<div style="text-align: left; display: inline-block;">
Your Html code here
</div>
</div>
</div>
</div>
With transforms being more ubiquitously supported these days, you can do this without knowing the width/height of the popup
.popup {
position: fixed;
top: 50%;
left: 50%;
-webkit-transform: translate(-50%, -50%);
transform: translate(-50%, -50%);
}
