CSS bottom

CSS bottom property decides the bottom offset (bottom edge of element offset from bottom edge of container) for positioned elements. An element is considered positioned if its position property has value other than static.

CSS property bottom

CSS version: CSS 2.1
Value: length | percentage | auto | inherit
Initial: auto
Applies to: positioned elements
Inherited: no
Percentage: percentage of height of containing block
Few points to note

  1. Property bottom can be applied to positioned elements (fixed, relative, absolute)
  2. For absolute element the offset is relative to nearest positioned container.
  3. For relative element the offset is relative to the element’s normal position itself.
  4. In case value is specified as percentage, it is percentage of containing block width.
  5. Negative values are ok.

  • 0
