CSS validation error in forms.css - Prosilver

Hello.

This ticket concerns Prosilver and prosilver-based styles. As I was finishing my Id_Xmas style, I wanted to verify its XHTML and CSS with the W3C validation tools.

Everything was fine on the XHTML side, but one error was found in the CSS, but I couldn't find what was wrong, so when I sent the style to validation, I left a notice about it. Here's what I had as reply when my style has been approved :

Notes from the Styles Team about your style:

[...]

The validation error is caused by the following in forms.css:

a.button1, input.button1, input.button3, a.button2, input.button2 {

	width: auto !important;

	padding-top: 1px;

	padding-bottom: 1px;

	font-family: "Lucida Grande", Verdana, Helvetica, Arial, sans-serif;

	color: #000;

	background: #FAFAFA none repeat-x top;

}

You have specified the background-position for the y-axis, but not for the x-axis.

Since I didn't do any modification in this file, I verified with Prosilver, by submitting phpBB.biz to the CSS 2.1 validation. The sams error was found !

So, this validation error is present in prosilver and so, all prosilver-based styles that haven't had this block of code modified in forms.css have the error.

So I send a ticket about it, so it can be implemented in 3.0.7.

Thanks in advance.
