failing W3 tests


Well-known member
Looking at the results from W3's validation tests,
it shows that xenforo is failing with bunches of errors. Granted on the html some of the errors are related to the fb integration stuff, but some others could be avoided.

In the future how problematic is this going to be when new browsers are more closely adhering to the W3 guidelines?

Browsers are never going to follow W3 guidelines entirely.

As you said, the majority of HTML errors are related to facebook, and a few other are things not supported by the HTML validator currently (The HTML5 validator is still completely experimental and doesn't support everything).

The CSS errors are mostly browser specific code or browser specific hacks for backwards compatibility, and have no impact on anything. If you use a filter, and filter out the browser specific code, you're left with ~40 errors, most of which are hacks (Such as _border, which is for >IE7).
