CSS Validation TIP(s)
For many web professionals, it can be tedious to review and edit code. Fortunately, there are many WYSIWYG editors (Dreamweaver) that allow users to validate work as they complete the project. However, if you don’t have the peripheral software, such as Dreamweaver, you may use alternative methods available online. In fact, the options are somewhat better depending on the version of the software you are using; you may have outdated validation libraries that aren’t always up to the task of proofing. The W3C CSS Validation Service is a free syntax and code check created by the W3C to help edit Cascading Style Sheets (CSS). You only need an internet connection, and a web host.
