## 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)
