Significant Bugs and Incompatibilities in IE6 and IE7

Posted on October 15, 2009. Filed under: Articles |

Following is a brief description of various bugs that occur in IE6 and IE7 that are not described or alluded to above. This list does not include items that lack support in all three browsers.

IE6 Bugs

  • Doesn’t support styling of the <abbr> element
  • Doesn’t support classes and IDs that begin with a hyphen or underscore
  • <select> elements always appear at the top of the stack, unaffected by z-index values
  • :hover pseudo-class values are ignored if anchor pseudo-classes are not in the correct order (:link, :visited, :hover)
  • An !important declaration on a property is overridden by a 2nd declaration of the same property in the same rule set that doesn’t use !important
  • height behaves like min-height
  • width behaves like min-width
  • Left and right margins are doubled on floated elements that touch their parents’ side edges
  • Dotted borders appear identical to dashed borders
  • line-through value for text-decoration property appears higher on the text than on other browsers
  • List items for an ordered list that have a layout will not increment their numbers, leaving all list items preceded by the number “1″
  • List items don’t support all possible values for list-style-type
  • List items with a specified list-style-image will not display the image if they are floated
  • Offers only partial support for @font-face
  • Some selectors will wrongly match comments and the doctype declaration
  • If an ID selector combined with a class selector is unmatched, the same ID selector combined with different class selectors will also be treated as unmatched

IE7 Bugs

  • List items for an ordered list that have a layout will not increment their numbers, leaving all list items preceded by the number “1″
  • List items don’t support all possible values for list-style-type
  • List items with a specified list-style-image will not display the image if they are floated
  • Offers only partial support for @font-face
