Attribute Clear
Clear is almost the opposite of float. The Clear property prevents component A from taking up the space of component B (with component B being the element using float). Sometimes we do not want to float in certain situations, we will use clear to overcome.
To put it simply, clear is used to solve the problem in the float property's notice above.
The float property can have one of the following values:
left: Overflow to the left.
right: Overflow to the right.
none: Allow overflow on both sides (default).
both: Do not allow overflow to either side
inherit : The element inherits the value from the parent float.
The most common way to use the Clear property is after you've used the Float property on an element. If an element is floated to the left, you should clear it to the left. Your Float element will continue to float, but the removed element will appear below it on the web page.
Clearfix
