CSS Layout - Float Examples
This page contains common float examples.
Grid of Boxes / Equal Width Boxes
Box 1
Box 2
Box 1
Box 2
Box 3
With the float property, it is easy to float boxes of content side by side:
Example
* { box-sizing: border-box;}.box { float: left; width: 33.33%; /* three
boxes (use 25% for four, and 50% for two, etc) */ padding:
50px; /* if you want space between the images */}

What is box-sizing?
You can easily create three floating boxes side by side. However, when you add something that enlarges the width of each box (e.g. padding or borders), the box will break. The box-sizing property allows us to include the padding and border in the box's total width (and height), making sure that the padding stays inside of the box and that it does not break.
You can read more about the box-sizing property in our CSS Box Sizing Chapter.
Images Side By Side
The grid of boxes can also be used to display images side by side:
Example
.img-container { float: left; width: 33.33%; /* three
containers (use 25% for four, and 50% for two, etc) */ padding:
5px; /* if you want space between the images */}

Equal Height Boxes
In the previous example, you learned how to float boxes side by side with an equal width. However, it is not easy to create floating boxes with equal heights. A quick fix
however, is to set a fixed height, like in the example below:
Box 1
Some content, some content, some content
Box 2
Some content, some content, some content
Some content, some content, some content
Some content, some content, some content
Example
.box { height: 500px;}

However, this is not very flexible. It is ok if you can guarantee that the boxes will always have the same amount of content in them.
But many times, the content is not the same. If you try the example above on a mobile phone, you will see that the second
box's content will be displayed outside of the box.
This is where CSS3 Flexbox comes in handy - as it can automatically stretch
boxes to be as long as the longest box:
Example
Using Flexbox to create flexible boxes:
Box 1 - This is some text to make sure that the content gets really tall. This is some text to make sure that the content gets really tall. This is some text to make sure that the content gets really tall.
Box 2 - My height will follow Box 1.

Web Layout Example
It is also common to do entire web layouts using the float property:
Example
.header, .footer { background-color: grey; color: white;
padding: 15px;}.column { float: left;
padding: 15px;}.clearfix::after { content:
""; clear: both; display: table;
}.menu {
width: 25%;}.content { width: 75%;}
