In have this style in the list, but I seemed that it's not work correctly. how convert this style to version 6.1 ?

6.2 should be backwards compatible to 6.1. where are you seeing the problems?<br />

Likewise I agree with Allen you should not be seeing errors due to CSS.<br /><br />There are a few new classes defined but they would not be called for in 6.1 but would not produce errors. The main difference between the CSS files in Threads is compliance from CSS 1 to CSS 2. Big change was you should see something like this in a 6.1 stylesheet<br /><br />body {<br /> background: #80e4ff;<br />}<br /><br />That would pass a CSS version 1 test<br /><br />In 6.2 which validates CSS version 2 you see this<br /><br />body {<br /> color: #000000;<br /> background: #80e4ff;<br /> font-family: Verdana, Arial, Helvetica, sans-serif;<br /> font-size: 9pt;<br />}<br /><br />All your doing is defining every variable and not leaving anything to guess. If anything you are leaving less room for error.
