How to vertically align div inside another div wit

问题:

Ok this is the div structure.

  <div class="DivParent"> 
  <a href="#">

  <div class="DivWhichNeedToBeVerticallyAligned"></div>

  </a>    
  </div>

DivParent has fixed width and height values but DivWhichNeedToBeVerticallyAligned does not have fixed height values.

If you make DivParent display:table-cell; you can vertically align DivWhichNeedToBeVerticallyAligned but i don't want to use that feature since it causes some mess.

A href tag link should be same size with the divParent i mean whole divparent has to be clickable. like display:block.

So are there any CSS way of vertically aligning or lightweight jquery solution would also help.

Thank you.

You can use an extra helper to achieve vertical alignment in a block with fixed height.

Look at this: http://jsfiddle.net/kizu/7Fewx/

There you must have a helper near a block you want to align with:

.DivHelper {
    display: inline-block;
    vertical-align: middle;
    height:100%;
}

And add display: inline-block; vertical-align: middle; to .DivWhichNeedToBeVerticallyAligned

There is no way to do this with CSS without knowing the height of the child div.

With jQuery, you could do something like this.

var parentHeight = $('#parent').height();
var childHeight = $('#child').height();
$('#child').css('margin-top', (parentHeight - childHeight) / 2);

if the parent don't have any other child. this would be a css only "hack"

DivParent{line-height:100px /*the div actual height*/ }
.DivWhichNeedToBeVerticallyAligned{display:inline-block}

another hack is

DivParent{height:100px; position:relative}
.DivWhichNeedToBeVerticallyAligned{height:20px; position:absolute; top:50%; margin-top:-10px;}

This solution works for me fine in modern browsers including IE 10 and above.

<div class="parent">
    <div class="child">Content here</div>
</div>

inlucluding this css

.parent {
  height: 700px;
  display: flex;
  justify-content: center;  
  align-items: center;
}
.child {
  width : 525px;
}

I have been using the following solution (with no positioning, no table-cell/table-row and no line height) since over a year, it works with IE 7 and 8 as well.

<style>
.outer {
    font-size: 0;
    width: 400px;
    height: 400px;
    background: orange;
    text-align: center;
    display: inline-block;
}

.outer .emptyDiv {
    height: 100%;
    background: orange;
    visibility: collapse;
}

.outer .inner {
    padding: 10px;
    background: red;
    font: bold 12px Arial;
}

.verticalCenter {
    display: inline-block;
    *display: inline;
    zoom: 1;
    vertical-align: middle;
}
</style>

<div class="outer">
    <div class="emptyDiv verticalCenter"></div>
    <div class="inner verticalCenter">
        <p>Line 1</p>
        <p>Line 2</p>
    </div>
</div>

Here is another option for modern browsers:

.child {
  position: absolute;
  left: 50%;
  top: 50%;
  -webkit-transform: translate(-50%, -50%);
  -moz-transform: translate(-50%, -50%);
  -ms-transform: translate(-50%, -50%);
  -o-transform: translate(-50%, -50%); 
     transform: translate(-50%, -50%);
}
