Align DIV's to bottom or baseline

Solution 1:

You need to add this:

#parentDiv {
  position: relative;
}

#parentDiv .childDiv {
  position: absolute;
  bottom: 0;
  left: 0;
}

When declaring absolute element, it is positioned according to its nearest parent that is not static (it must be absolute, relative or fixed).

Solution 2:

Seven years later searches for vertical alignment still bring up this question, so I'll post another solution we have available to us now: flexbox positioning. Just set display:flex; justify-content: flex-end; flex-direction: column on the parent div (demonstrated in this fiddle as well):

#parentDiv
{
  display: flex;
  justify-content: flex-end;
  flex-direction: column;
  width:300px;
  height:300px;
  background-color:#ccc;
  background-repeat:repeat
}

Solution 3:

Use the CSS display values of table and table-cell:

HTML

<html>
<body>

  <div class="valign bottom">
    <div>

      <div>my bottom aligned div 1</div>
      <div>my bottom aligned div 2</div>
      <div>my bottom aligned div 3</div>

    </div>
  </div>

</body>
</html>

CSS

html,body {
    width: 100%;
    height: 100%;
}
.valign {
    display: table;
    width: 100%;
    height: 100%;
}
.valign > div {
    display: table-cell;
    width: 100%;
    height: 100%;
}
.valign.bottom > div {
    vertical-align: bottom;
}

I've created a JSBin demo here: http://jsbin.com/INOnAkuF/2/edit

The demo also has an example how to vertically center align using the same technique.

Solution 4:

this works (i only tested ie & ff):

<html>
<head>
    <style type="text/css">
        #parent {
            height: 300px;
            width: 300px;
            background-color: #ccc;
            border: 1px solid red;
            position: relative;
        }
        #child  {
            height: 100px;
            width: 30px;
            background-color: #eee;
            border: 1px solid green;
            position: absolute;
            bottom: 0;
            left: 0;
        }
    </style>
</head>
<body>
    <div id="parent">parent
        <div id="child">child</div>
    </div>
    outside
</body>
</html>

hope that helps.
