2.1.25 [CSS-Level2-2009] Section 8.3, Margin properties: 'margin-top', 'margin-right', 'margin-bottom', 'margin-left', and 'margin'

V0035:

The specification states:

 ‘margin-top’, ‘margin-bottom’
  
 Value:                 <margin-width> | inherit
 Initial:               0
 Applies to:            all elements except elements with table display types other 
                        than table-caption, table and inline-table
 Inherited:             no
 Percentages:           refer to width of containing block
 Media:                 visual
 Computed value:        the percentage as specified or the absolute length
  
 These properties have no effect on non-replaced inline elements.

Quirks Mode and IE7 Mode (All Versions)

The margin-top and the margin-bottom properties are not ignored when applied to elements with the following table display types:

  • table-cell

  • table-row-group

  • table-column-group

  • table-header-group

  • table-footer-group

  • table-row

  • table-column

IE8 Mode (All Versions)

When a parent element has a percentage-based padding value specified (for example, padding-top: 10%) and a child element has a vertical margin specified (for example, margin-top:100px), the vertical margin is ignored by the child element and then applied to the parent element instead.

All Document Modes (All Versions)

The width of shrink-to-fit elements is incorrect when children elements have width and horizontal percentage-based margins.

Content outside the page box is discarded when negative margins are used.

 Inherited:             no 
 Percentages:           refer to width of containing block 
 Media:                 visual 
 Computed value:        the percentage as specified or the absolute length
  
 These properties set the top, right, bottom, and left margin of a box.
