4. Reading Validation Messages

Reading Validation Messages

The TopStyle Style Checker returns four kind of validation messages:

Errors: The style sheet contains unknown properties, unbalanced comments, broken URLs and other problems that will significantly impact the style sheet
Warnings: The style sheet contains empty rules, duplicate properties (ie: "Color" defined twice in the same rule), duplicate selectors and other problems that may impact the rendering
Hints: The style violates recommended practices (example: a color is specified for a rule without a background color)
Browser Tips: These are warnings about particular browsers, usually bugs in their CSS implementation (ie: Netscape incorrectly treats URLs as relative to the HTML document instead of the style sheet)
