In ua.css, one finds the following rules for table elements: table { display: table; /* ... */ background: transparent; } "background: transparent" is redundant in ua.css, since "transparent" is the inital value. td, th { vertical-align: inherit; background: inherit; /* ... */ } "background: inherit" here will cause the table's background image to be drawn for each cell, instead of backing the table. Ditto for tr, tbody, thead and tfoot, which all have "background: inherit".

ua.css was recently changed so that these internal table elements only inherit background-color. This is still not 100% correct and we need 2 ua.css files, one for NavQuirks mode and one for Standard mode. The current ua.css tries to both jobs. Peter, please decide if this is still a bug.

Err, BTW, the 1999-03-23 build still has the old rules. Also, you don't want to be inherting *any* of the background, do you? If cells inherit background-color, then any background image set on tables or rows will be overwritten by the cells' backgrounds. You want *no* background rules on *any* table elements in ua.css, letting the initial value of "transparent" to do its work.

ua.css, this bug, and and many other table style bugs will be easily fixed after Peter adds a new style rule (in the code) which gets applied after the html style sheet but before the css style sheets.

Marking verified. These rules no longer appear in ua.css. Background issues are now different in standard and quirks mode.
