Vertically centering a div inside another div [duplicate]

Answer 1

tl;dr

Vertical align middle works, but you will have to use table-cell on your parent element and inline-block on the child.

This solution is not going to work in IE6 & 7.
Yours is the safer way to go for those.
But since you tagged your question with CSS3 and HTML5 I was thinking that you don't mind using a modern solution.

The classic solution (table layout)

This was my original answer. It still works fine and is the solution with the widest support. Table-layout will impact your rendering performance so I would suggest that you use one of the more modern solutions.

Here is an example

Tested in:

• FF3.5+
• FF4+
• Safari 5+
• Chrome 11+
• IE9+

HTML

your content

CSS

.cn {
  display: table-cell;
  width: 500px;
  height: 500px;
  vertical-align: middle;
  text-align: center;
}

.inner {
  display: inline-block;
  width: 200px; height: 200px;
}

Modern solution (transform)

Since transforms are fairly well supported now there is an easier way to do it.

CSS

.cn {
  position: relative;
  width: 500px;
  height: 500px;
}

.inner {
  position: absolute;
  top: 50%; left: 50%;
  transform: translate(-50%,-50%);
  width: 200px;
  height: 200px;
}

♥ my favourite modern solution (flexbox)

I started to use flexbox more and more its also well supported now Its by far the easiest way.

CSS

.cn {
  display: flex;
  justify-content: center;
  align-items: center; 
}
