The clear CSS property sets whether an element must be moved below (cleared) floating elements that precede it. The clear property applies to floating and non-floating elements.

Values

  • none
    • : Is a keyword indicating that the element is not moved down to clear past floating elements.
  • left
    • : Is a keyword indicating that the element is moved down to clear past left floats.
  • right
    • : Is a keyword indicating that the element is moved down to clear past right floats.
  • both
    • : Is a keyword indicating that the element is moved down to clear past both left and right floats.
  • inline-start
    • : Is a keyword indicating that the element is moved down to clear floats on start side of its containing block, that is the left floats on ltr scripts and the right floats on rtl scripts.
  • inline-end
    • : Is a keyword indicating that the element is moved down to clear floats on end side of its containing block, that is the right floats on ltr scripts and the left floats on rtl scripts.

Description

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. The non-floated block's top margin collapses.

Vertical margins between two floated elements on the other hand will not collapse. When applied to floating elements, the margin edge of the bottom element is moved 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, set the value of the element's {{cssxref("display")}} property to flow-root.

css
#container {
  display: flow-root;
}
