What is CSS Float?


With CSS float, an element can be pushed to the left or right, allowing other elements to wrap around it.
Float is very often used for images, but it is also useful when working with layouts.
How Elements Float
Elements are floated horizontally, this means that an element can only be floated left or right, not up or down.
A floated element will move as far to the left or right as it can. Usually this means all the way to the left or right of the containing element.
The elements after the floating element will flow around it.
The elements before the floating element will not be affected.
If an image is floated to the right, a following text flows around it, to the left:
Example
<html>
<head>
<style type="text/css">
img
{
float:right;
}
</style>
</head>
<body>
<p>In the paragraph below, we have added an image with style <b>float:right</b>. The result is that the image will float to the right in the paragraph.</p>
<p>
<img src="logocss.gif" width="95" height="84" />
This is some text. This is some text. This is some text.
This is some text. This is some text. This is some text.
This is some text. This is some text. This is some text.

Floating Elements Next to Each Other
If you place several floating elements after each other, they will float next to each other if there is room.
Here we have made an image gallery using the float property:
Example
<html>
<head>
<style type="text/css">
.thumbnail
{
float:left;
width:110px;
height:90px;
margin:5px;
}
</style>
</head>
<body>
<h3>Image Gallery</h3>
<p>Try resizing the window to see what happens when the images does not have enough room.</p>
<img class="thumbnail" src="klematis_small.jpg" width="107" height="90">
<img class="thumbnail" src="klematis2_small.jpg" width="107" height="80">
<img class="thumbnail" src="klematis3_small.jpg" width="116" height="90">
<img class="thumbnail" src="klematis4_small.jpg" width="120" height="90">
<img class="thumbnail" src="klematis_small.jpg" width="107" height="90">
<img class="thumbnail" src="klematis2_small.jpg" width="107" height="80">
<img class="thumbnail" src="klematis3_small.jpg" width="116" height="90">
<img class="thumbnail" src="klematis4_small.jpg" width="120" height="90">
</body>
</html>

Turning off Float - Using Clear
Elements after the floating element will flow around it. To avoid this, use the clear property.
The clear property specifies which sides of an element other floating elements are not allowed.
Add a text line into the image gallery, using the clear property:
Example
<html>
<head>
<style type="text/css">
.thumbnail
{
float:left;
width:110px;
height:90px;
margin:5px;
}
.text_line
{
clear:both;
margin-bottom:2px;
}
</style>
</head>
<body>

Creating a horizontal menu
Use float with a list of hyperlinks to create a horizontal menu.
Use float with a list of hyperlinks to create a horizontal menu.
Example
<head>
<style type="text/css">
ul
{
float:left;
width:100%;
padding:0;
margin:0;
list-style-type:none;
}
a
{
float:left;
width:6em;
text-decoration:none;
color:white;
background-color:purple;
padding:0.2em 0.6em;
border-right:1px solid white;
}
a:hover {background-color:#ff3300;}
li {display:inline;}
</style>
</head>
<body>
<ul>
<li><a href="#">Link one</a></li>
<li><a href="#">Link two</a></li>
<li><a href="#">Link three</a></li>
<li><a href="#">Link four</a></li>
</ul>
<p>
In the example above, we let the ul element and the a element float to the left.
The li elements will be displayed as inline elements (no line break before or after the element). This forces the list to be on one line.
The ul element has a width of 100% and each hyperlink in the list has a width of 6em (6 times the size of the current font).
We add some colors and borders to make it more fancy.
