Elements below a float will come up around the floated element. That's what you learned in the last chapter. For example, if an image is floated left, the text will wrap up around it.
Sometimes, though, you don't want adjacent elements all to float up around the floated element! This is where you'll need to clear a float. Think of when you 'clear' an obstacle, for example; it means it's out of your way. When you want a floated element to be out of an other element's way, clear it.
Take the example of this simple article with an image that floats to the right:

* {
font-family: Futura;
}
article {
background-color: #c1e0f4;
padding: 10px;
}
img {
width: 200px;
float: right;
margin-right: 10px;
margin-bottom: 10px;
}If only the first paragraph were relevant to the image, we may not want the second paragraph also floating up there next to it! The clear property will let us specify that we want a particular element to be below a floated element, not next to it.
The clear property can have a value of left , right , or both (meaning it will clear floated elements to the left, right, or either direction; "both" is probably what you'll see most often because it covers all cases):
#clear {
clear: both;
}
Knowing how to float elements and add the clear property when you want other elements to not be affected by the float is important. Remember, though, that you should not be using these techniques in your layouts anymore.
Recap
Just stick with float and clear usage in this very specific case of wrapping text around images, and you should be fine!
