clear

The clear CSS property specifies whether an element can be next to floating elements that precede it or must be moved down (cleared) below them. The clear property applies to both floating and non-floating elements.

/* Keyword values */
clear: none;
clear: left;
clear: right;
clear: both;
clear: inline-start;
clear: inline-end;

/* Global values */
clear: inherit;
clear: initial;
clear: unset;

When applied to non-floating blocks, it moves the border edge of the element down until it is below the margin edge of all relevant floats. This movement (when it happens) causes margin collapsing not to occur.

When applied to floating elements, it moves the margin edge of the element below the margin edge of all relevant floats. This affects the position of later floats, since later floats cannot be positioned higher than earlier ones.

The floats that are relevant to be cleared are the earlier floats within the same block formatting context.

Note: If an element contains only floated elements, its height collapses to nothing. If you want it to always be able to resize, so that it contains floating elements inside it, you need to self-clear its children. This is called clearfix, and one way to do it is clear a replaced ::after pseudo-element on it.

#container::after { 
  content: "";
  display: block; 
  clear: both;
}
Initial value none
Applies to block-level elements
Inherited no
