What is the effect of clearing floats?

This article introduces how to eliminate the impact of floating, the content is very detailed, interested friends can use for reference, I hope it can be helpful to you.

Floating causes the parent element to collapse as shown in the figure:

Solution:

Parent element overflow:hidden, as shown in the figure

Insert the child element clear at the end, as shown in the figure

Why does the parent element overflow:hidden solve the collapse problem?

Overflow:hidden means to trim and hide the excess.

So if the element of float does not occupy the position of ordinary stream, the inclusion block of ordinary stream should be highly trimmed and hidden according to the content.

If the height is the default value auto, then it will be trimmed without calculating the height of the floating elements within it.

It is possible to cut float, which is contrary to the common sense of layout.

If you understand BFC, the problem will be easily solved. Let's see what BFC says.

In the BFC layout specification, floating elements are also involved in calculating the height of BFC.

Overflow:hidden creates a BFC.

Why does inserting a child element clear at the end solve the collapse problem?

Take a look at what a clear float is, and this problem can also be easily solved.

If the declaration is cleared to the left or right, the upper outer border of the element is just below the lower outer margin boundary of the floating element on that edge.
