Some properties in a rule will be ignored due to the display of the element. This leads to misunderstandings around how a rule should work and increases file size unnecessarily.

Examples

  • display: inline shouldn't use width, height, margin-top, margin-bottom and float.
  • display: inline-block shouldn't use float.
  • display: block shouldn't use vertical-align.
  • display: table-* shouldn't use margin or float.

How do I fix this ?

Remove these ignored or problematic properties (as they should have very little or no effect on the display of the element), thereby decreasing file size and improving performance.
