What does clear mean in CSS?

The clear property is used to control the area around floating elements. It specifies how subsequent elements are positioned when a floated element is encountered.

Detailed explanation:

Floating elements will break away from the normal document flow and be arranged along the edges of their parent elements. The clear attribute allows subsequent elements to skip over floated elements instead of surrounding them.

There are three clear values:

• left: The element starts from the left side of the floating element
• right: Elements start from the right side of the floated element
• both:Elements start from the left and right sides of the floated element

Usage example:

<div class="container">
  <div class="float-left">浮动元素</div>
  <div class="clear"></div>
  <div>后续元素</div>
</div>

In the above example, the .clear class has the clear: both; attribute applied. This will cause subsequent elements to start to the left and right of the floated element, creating a gap so that subsequent elements will not be wrapped by the floated element.
