CSS Basic Tutorial
CSS Flexbox
In CSS, the clear
property is used to control the behavior of an element that follows a floated element. Specifically, it ensures that the element appears below any preceding floated elements, rather than wrapping around them.
clear: none | left | right | both | inherit;
When working with layouts where floated elements are inside a parent container, clear
can be useful to ensure the container expands to fit its floated children.
