# TalkAbout the Aptana CSS Editor [edit]

How do i turn off the error checking in CSS files? we use some unofficial css, such as

filter: alpha(opacity=50); opacity: 0.50; -moz-opacity: 0.50;

to achieve alpha channels, and they're all showing up as errors. More anoyingly, they are cause the eclipse file browser to mark the entire directory path to the css file as having errors.

I've gone ahead and logged your request as a Trac entry. You should be seeing this appear as an option in a new beta release in the near future:
