LEFT & RIGHT ALIGNING BY POSITION PROPERTY


Left and Right Aligning Using the position Property

One method of aligning elements is to use absolute positioning:

Example

.right
{
position:absolute;
right:0px;
width:300px;
background-color:#b0e0e6;
}

HINT: Absolute positioned elements are removed from the normal flow, and can overlap elements.


Crossbrowser Compatibility Issues

When aligning elements like this, it is always a good idea to predefine margin and padding for the <body> element. This is to avoid visual differences in different browsers.
There is a problem with IE8 and earlier, when using the position property. If a container element (in our case <div class="container">) has a specified width, and the !DOCTYPE declaration is missing, IE8 and earlier versions will add a 17px margin on the right side. This seems to be space reserved for a scrollbar. Always set the !DOCTYPE declaration when using the position property:


Example

body
{
margin:0;
padding:0;
}
.container
{
position:relative;
width:100%;
}
.right
{
position:absolute;
right:0px;
width:300px;
background-color:#b0e0e6;
}
