The width property
The width property sets an element
width. The property value is any
size units
or the key property auto, which allows
the browser to independently calculate an
element size (default behavior).
Syntax
selector {
width: value;
}
Example
Set the element width
to 300px:
<div id="elem"></div>
#elem {
width: 300px;
height: 100px;
border: 1px solid black;
}
:
Example
Let's make the element take up 70%
of its parent width (in our case this will
be the browser window):
<div id="elem"></div>
#elem {
width: 70%;
height: 100px;
border: 1px solid black;
}
