This is where you set up options that affect the style checker and its output. The style checker is included in the standard and professional editions, but not the lite edition.
The style checker is designed to check CSS1 and CSS2 syntax. It also checks some proprietary CSS syntax (like Microsoft's scrollbar properties). Many problems will be found by the CSS syntax checker but not all CSS is checked.
Style Checking Options
| • | Enable CSS style checking - Check this box to enable CSS style checking. This option is enabled by default. |
| • | Allow underscores in class and ID names - Check this box to allow underscore characters (_) in CSS class and ID names. An errata document to CSS2 allows underscores. Underscores should be well supported in current versions of modern browsers. Older browsers like Netscape Navigator 4.x and Opera 5.x and older will likely ignore any class or ID name that contains underscores, though Internet Explorer 4.x and above allow underscores. It is recommended that you uncheck this option only if older browser support is needed. You may also want to consider using the hyphen character (-) instead of an underscore. This option is enabled by default. (New v9.00) |
Style Checker Flags
These flags function similarly to the tag name program flags. You can disable or enable them as you wish. To avoid confusion with the tag name program flags and for other design reasons, the style checker flags start at 600.
