Styles for <tr> seem to be repeated for every <td> in it. I’ve made a simple example on http://mathiasbynens.be/demo/webkit-tr-css, where the <td> gets a gradient background-image through CSS. (Note that I avoided the use of CSS3 gradients to avoid complexity and confusion — it’s just a simple test case.) In WebKit, the image is repeated for every <td>: http://i.imgur.com/vXNd9.png In Firefox or Opera, it works as expected: http://i.imgur.com/V7HvU.png
This is not necessary related to the gradient. Instead of the gradient, you can use another image and still reproduce the problem.
(In reply to comment #1) > This is not necessary related to the gradient. Instead of the gradient, you can use another image and still reproduce the problem. For the record, I never said it was. I simply used a background image that happened to be a gradient (for clarity). Of course it doesn’t matter which image is used.
