This is where you set up options that affect the style checker and its output.

The CSS checker is designed to check most CSS properties for syntax and warn about obsolete or outdated CSS. It also checks some proprietary CSS syntax (like Microsoft's "scrollbar-*" properties). Many CSS problems will be found by the CSS syntax checker but not all CSS is checked.

CSS Checker Options

Enable CSS style checking in HTML documents - Check this box to enable CSS style checking in HTML/XHTML documents. This does not affect style checking in CSS documents. This option is enabled by default.

Check "style" attribute for SVG elements - Check this box to check the value of the "style" attribute for SVG elements (where made possible by the configuration file). If unchecked then the value of the "style" attribute when used with SVG elements will be ignored. This option is enabled by default. (New v17.00)

Check for unused inline classes, IDs, and type selectors - Check this box to perform some simple checks on inline CSS classes, IDs, and type selectors to help ensure that they are actually used in the document. This will help you find unnecessary inline CSS that does not have any effect by generating additional warning messages for inline CSS classes, IDs, and type selectors that appear to be unused (one warning message for unused classes, one for unused IDs, and one for unused type selectors). For example, if an inline CSS class called ".myclass" is declared and "myclass" is never specified in any "class" attribute then a wa        rning message will be generated (but only if the validation has not prematurely terminated due to other errors or problems). This option is enabled by default. (New v18.00)
