Background colors given to <col>, <tr>, and <tbody> on a table that is supposed to be invisible (visibility: hidden) still show up. Backgrounds given to individual cells or to elements inside cells are not shown (like expected).

Internet Explorer crashes when a DOM tree traversing JS function is run on an element with display: none; position: absolute that has child elements.

The crash occurs when assigning the result of a unsuccessful document.getElementById() call to a property of one of the children in the hidden element.

When changing a parent element's class via JavaScript/DOM, an initial position:absolute declaration sticks. The problem is corrected by applying a position:relative declaration to the parent element's children.

In Opera 8.5, putting an absolutely positioned element inside a fixed positioned element results in the absolute positioned block disappearing completely.

I just added the (Orphaned) category, which contains all bug reports that no longer have test pages. I hope a friendly visitor will adopt them by creating a test page for the described bug.

If you create a new test page, leave the URL a comment in the original bug report. If I accept the new test page, you'll get the official credits on the report page.

All in all I'm rather pleased that only 22 out of 186 bug reports (12 %) turn out to be orphaned. In general people who post bug reports here are serious about maintaining them. Good to know.

Opera 7.x-8.5 will add padding-bottom to an object that is equal to the border-top if you use border-width and have the object positioned bottom.

I have found a workaround. If you do not have four seperate values for border-width the bug isn't rendered. You can also use border-color and border-style and use border: to set four seperate values for border-width without actually using the border-width syntax.

Experimenting with position: relative styles I noticed this inconsistent behavior of IE6. The image on the pages vanishes when a TD is shown/hidden, even though it is not involved in the javascript action.

In Internet Explorer 6.0 and higher, setting html, body {position: relative;} while in strict mode causes the browser to disallow scrolling. I don't know of any real-world applications where this would be a problem, but it's still a bug.

In Safari the entire body disappears if you set position: relative on the HTML first, and then on the BODY. Safari crashes if you check BODY, then HTML, then uncheck BODY.

Workarounds include using quirks mode, or playing it safe and avoiding setting positioning to the html element.

Text inside a display:-moz-inline-block element cannot be aligned. Not only that, it doesn't do word wrapping.

Using firefox in Windows and Linux (same version) i get a problem where i cannot specify a shadow underneath text to be consistent, because the margin/padding differences are throwing me out - i have set paddings and margins of all elements to 0 - except the one i wish to change... it's highly annoying!

Setting up a row of floats in Explorer 6 can lead to a plethora of erratic behavior, namely duplicate characters; in this bug report, I go into detail on some pure-CSS triggers which can make these extra characters appear, examples on how the bug is triggered, and different ways to combat it.
Note that these bugs are not caused by comments in your XHTML, as is the well known original Duplicate Characters Bug.
