Fix Problems Easily

You can fix problems efficiently using the Diagnostics window. On it you can:

Review all the problems on the site
See the full source at a location
Go to the position of a problem in the source
Open locations in your browser
Categorize diagnostics

Find Real Problems

Diagnostic categories let you see the diagnostics that you want when you want. If you intentionally use non-standard code, such as WAI-ARIA attributes or browser specific CSS properties, manually filtering out some diagnostics to catch the real errors can be difficult. Diagnostic categories automatically filter diagnostics so you can find real problems easily.

You don't have to categorize every diagnostic. Categories group diagnostics by description so when you move one diagnostic to a category, all diagnostics with the same description move to the category. This lets you quickly customize WebLight to let you find real problems efficiently.
