Align vertically using CSS 3
With CSS 3, are there any way to vertically align an block element? Do you have an example? Thank y开发者_JAVA百科ou.
Was looking at this problem recently, and tried:
HTML:
<body>
<div id="my-div"></div>
</body>
CSS:
#my-div {
position: absolute;
height: 100px;
width: 100px;
left: 50%;
top: 50%;
background: red;
transform: translate(-50%, -50%);
-webkit-transform: translate(-50%, -50%);
-moz-transform: translate(-50%, -50%);
-ms-transform: translate(-50%, -50%);
}
Here's the Fiddle:

It even works when using "width/height: auto", in the place of fixed dimensions. Tested on the latest versions on Firefox, Chrome, and IE (* gasp *).
Note: This example uses the draft version of the Flexible Box Layout Module. It has been superseded by the incompatible modern specification.
Center the child elements of a div box by using the box-align and box-pack properties together.
Example:
div
{
width:350px;
height:100px;
border:1px solid black;
/* Internet Explorer 10 */
display:-ms-flexbox;
-ms-flex-pack:center;
-ms-flex-align:center;
/* Firefox */
display:-moz-box;
-moz-box-pack:center;
-moz-box-align:center;
/* Safari, Opera, and Chrome */
display:-webkit-box;
-webkit-box-pack:center;
-webkit-box-align:center;
/* W3C */
display:box;
box-pack:center;
box-align:center;
}
Using Flexbox:
<style>
.container {
display: flex;
align-items: center; /* Vertical align */
justify-content: center; /* Horizontal align */
}
</style>
<div class="container">
<div class="block"></div>
</div>
Centers block inside container vertically (and horizontally).

a couple ways:
1. Absolute positioning-- you need to have a declared height to make this work:
<div>
<div class='center'>Hey</div>
</div>
div {height: 100%; width: 100%; position: relative}
div.center {
width: 100px;
height: 100px;
top: 50%;
margin-top: -50px;
}
*2. Use display: table http://jsfiddle.net/B7CpL/2/ *
<div>
<img src="/img.png" />
<div class="text">text centered with image</div>
</div>
div {
display: table;
vertical-align: middle
}
div img,
div.text {
display: table-cell;
vertical-align: middle
}

There is a simple way to align vertically and horizontally a div in css.
Just put a height to your div and apply this style
.hv-center {
margin: auto;
position: absolute;
top: 0; left: 0; bottom: 0; right: 0;
}
Hope this helped.
I always using tutorial from this article to center things. It's great
div.container3 {
height: 10em;
position: relative } /* 1 */
div.container3 p {
margin: 0;
position: absolute; /* 2 */
top: 50%; /* 3 */
transform: translate(0, -50%) } /* 4 */
The essential rules are:
- Make the container relatively positioned, which declares it to be a container for absolutely positioned elements.
- Make the element itself absolutely positioned.
- Place it halfway down the container with 'top: 50%'. (Note that 50%' here means 50% of the height of the container.)
- Use a translation to move the element up by half its own height. (The '50%' in 'translate(0, -50%)' refers to the height of the element itself.)
Try this also work perfectly:
html:
<body>
<div id="my-div"></div>
</body>
css:
#my-div {
position: absolute;
height: 100px;
width: 100px;
left: 50%;
top: 50%;
background: red;
display: table-cell;
vertical-align: middle
}
You can vertically align by setting an element to display: inline-block, then setting vertical-align: middle;
