"Internet Explorer takes their usual route and ignores the required comma separated values and only supports the optional comma-less method. So, even though using commas is the correct method, you'll need to drop the commas in order for the clip property to work in Internet Explorer (even in IE7)." taken from Misunderstood CSS Clip by Nicholas Gagne. This is also reported in the tutorial Creating Thumbnails Using the CSS Clip Property by seifi.org in the following manner:
"The W3C recommendation suggests using commas between the coordinates, however this is broken in Internet Explorer. Strangely using the commas in IE does not work when in standards-compliant mode, but it does work when in quirks mode.".

Firefox 1.5.0.7, Firefox 2.0, Opera 9.02, Konqueror 3.5.5, Safari 2.0, Safari 3.0.2, Hv3 TKHTML alpha 16 all pass this test.

No problem whatsoever with Firefox 2, Opera 9, Safari 2, Safari 3.0.2, Konqueror 3.5.8, Amaya 9.55, Hv3 TKHTML alpha 16. Absolutely impossible for MSIE 6 and MSIE 7.

Credit goes to Lutz-Peter Hooge for filing a float bug with a similar testcase.

52- Table border conflict resolution This example comes directly from section 17.6.2 of CSS 2.0 spec. and section 17.6.2.1 of latest CSS 2.1 spec..

73- Vertical-align should NOT and must NOT apply to <ul> with list-style-image. Firefox 2.0.0.6, Opera 9.23, Opera 9.50, Safari 3.0.3, Seamonkey 2.0a1pre, Konqueror 3.5.2, Seamonkey 1.x, K-meleon 1.x, Galeon 2, Epiphany 2, NS 6.2, NS 7.0, NS 7.2 all pass this test.

84- Internet Explorer 5, Internet Explorer 6, Internet Explorer 7 and Internet Explorer 8 beta 1 do not increase or decrease correctly nested block-level elements when they use font-size: 1em: EM text resizing bug demo. This is a widely known and very frequently encountered and reported bug in Internet Explorer 5, Internet Explorer 6 and Internet Explorer 7 . Basically, the problem with setting the font-size in EM is that increasing or decreasing text size will grow or shrink fonts out of proportion (exponentially) for nested block-level elements. Firefox 2.0.0.8, Opera 9.50, Safari 3.0.3, Konqueror 3.5.5, Seamonkey 1.x, Seamonkey 2.0a1pre, K-meleon 1.x, Galeon 2, Epiphany 2, NS 6.1, NS 6.2, NS 7.0, NS 7.2, Hv3 TKHTML alpha 16, Amaya 9.55 all pass this test. This bug has been reported at connect's IE beta feedback as bug 339085. This IE 5+ bug has been reported many times, in many newsgroup discussion forums on web authoring, in various webpages, blogs from web developers. It's really worth mentioning a few of them and quoting some highly relevant testimonials describing accurately the effects of this bug:

"IE gets its text resizing horribly wrong when just using ems. (...) bump the text size up or down, and you'll notice that IE scales ems far more drastically than percentages, resulting in too big / too small text."
from Patrick H. Lauke, May 18th 2004, Weblog comments: How to size text using ems

"text sized in ems can be resized across all browsers. However IE6 and IE7 unacceptably exaggerate the smallness and largeness of the resized text"
from Richard Rutter, November 20th 2007, How to Size Text in CSS

"However, (gasp) IE has a problem with ems. Resizing text from medium (default) to large in IE5/6 would lead to a huge increase in font size rather than the gradual one expected"
from Jon Tan, September 27th 2007, The Incredible Em & Elastic Layouts with CSS

"If for instance you set the root element (either <body> or <html>) to font-size:1em, then just setting View > Text Size to 'smaller' can cause the text to become unreadably small."
from css-discuss.incutio.com, 2007, UsingEms, A word of caution concerning Internet Explorer

"When I tried font-size:1em, my IE6 browser 'text size' will toggle from very tiny to very huge.
....Not acceptable for accessibility!"
from Krystof, August 29th 2005, Weblog comments: How to size text using ems

"Simply put, IE for Windows' relative font size inheritance cascade is broken. (...) If you find it necessary to size through cascade, you'll find % works more reliably than ems."
from InternetExplorerWinBugs, IE Font Sizing Bugs: Inheritance at css-discuss.incutio.com

Only 2 people explained and documented this bug in detail (with screenshots, examples, demos):

em font-resizing bug in IE5 - IE7 by Gunlaug & Georg, November 20th 2005.

Credit must go to Alice for reporting this bug in duplicate line in IE7 post in comp.infosystems.www.authoring.html and in Emory's On Silverlake - Dinner Menu (reduced testcase).

99- Padding and border are rendered beneath body node. Since the blue-bordered inline-elements seem to have a lower z-index than the red bordered body node in Internet Explorer 6 and in Internet 7, then the border and padding areas are not visible, not viewable, seem to be truncated. This is most likely the same bug as the Disappearing border-top bug reported by Ben Hollis and the same bug that has been affecting this 1997 Web Standards Project basic testcase. Firefox 1.x, Firefox 2.x, Safari 2.0.4, Safari 3.0.4, Opera 9.25, Opera 9.50, Konqueror 3.5.8, Hv3 TKHTML alpha 16, Seamonkey 1.x, Seamonkey 2.x, K-meleon 1.x, NS 6.2, NS 7.0, NS 7.2, Galeon 2, Epiphany 2 all pass this test.

4. a stacking level for floats and their contents.
5. a stacking level for in-flow inline-level descendants. (...)" CSS 2.1, Section 9.9.1 Layered presentation; Specifying the stack level: the 'z-index' property

100- A negative margin-right is incorrectly rendered in a nested block. This bug happens often when designing, building a CSS columnar webpage template and is a great source of frustration among web authors.

102- Float, clear and margin bug Internet Explorer 6 and Internet Explorer 7 fail to clear a floated-left block. Internet Explorer 7 will render the margin-bottom of the last in-flow block before clearing.

Credit must go to Sjaak Priester for providing a testcase on this precise bug.

107- Text-align should not affect how a nested block-level element is horizontally aligned inside its containing block. A table nested inside a cell formated with text-align: center will be centered within its containing block when only its text and inline content should be centered. Firefox 1.x, Firefox 2.x, Firefox 3, Opera 9.26, Opera 9.50, Safari 2.0.4, Safari 3.0.4, Seamonkey 1.x, Seamonkey 2.x, Konqueror 3.5.8, K-meleon 1.x, Galeon 2, Epiphany 2, NS 7.0, NS 7.2, Hv3 TKHTML alpha 16, Amaya 9.55, Dillo 0.8.6 all pass this test.

117- Support for <option disabled> in Internet Explorer. Lack of support for <option disabled> in a select (drop-down list) has been mentioned, explained, utterly documented, testcase-ed by many in all kinds of forums, webpages, public lists of bugs, web authoring forum discussions over the last 5 years. Firefox 1.5, Firefox 2, Firefox 3, Opera 9.27, Opera 9.50, Safari 3.1, Seamonkey 1.x, Seamonkey 2.x, NS 7.0, NS 7.2, K-meleon 1.x, Galeon 2 and Epiphany 2 all pass this test.
