CSS Test Suite Results: MS Internet Explorer For Windows 4.01 SP1

Last Tested: 1998 July 14.

This list of bugs has not yet been updated to include those bugs uncovered by the new version of the CSS Test Suite, released 1998 December 17. The additions to the test suite are significant, and will include many new bug reports.


The list that follows is a list of bugs in the browser, that is, what is described is in error. I have also included a few partially supported features as bugs.

Miscellaneous import problems
1.4, 1.5
Class/ID selectors should not be allowed to begin with digits. The browser displays incorrect behavior, as explained in the link to the test. It should ignore the properties, since selectors should not begin with digits. If it accepts them, then authors using MSIE would not realize that what they did was wrong and not supported by other browsers.
Line has underline and overstrike.
No oblique fonts -- can this be done in Windows??
Default font size is not medium, as it should be.
The line-height percentages are interpreted relative to normal (ca. 120%) rather than to the font-size.
5.3.4, 5.3.6, 5.3.7
Repeat-x and repeat-y do not tile in both directions.
Underlining does not stay the same color throughout the paragraph.
Not all "align"s work.
Strange behavior with negative line height.
5.5.01, 5.5.03
top-margin and bottom-margin in percentage units behave oddly (and differently in and out of TABLE - percent value may be referring to height instead of width when outside of TABLE
5.5.06, 5.5.08 5.5.10
top-padding and bottom-padding in percentage units behave oddly (but the same this time)
5.5.07, 5.5.10
The right-padding is expanded due to justification of text. Is this bad?
border-style: dashed and border-style: dotted do not work.
5.5.25 float
The display tag is only partially supported: none works for a SPAN but not a P (but it makes the color:red invalid), and the list-item does nothing.
The horizontal alignment of the list markers is wrong. See the CSS2 specs.
The list-style: inside only works partially for upper-alpha
Decimal points in percentages are not supported.

Unsupported Features

Valid HTML 4.0!
