The following screen shots show CSE HTML Validator Pro.
CSE HTML Validator is extremely configurable. Many validator messages can be individually disabled or the message type can be changed to suit your specific requirements.
CSE HTML Validator Standard, Pro, and Enterprise include an integrated web browser (requires Internet Explorer). Browse the web with the integrated browser and HTML Validator simultaneously displays the HTML source of the page that you are viewing. HTML Validator can automatically validate the pages you visit as you browse the web! This is great for testing the output of dynamic pages that use ASP, PHP, CFML, or similar technologies. The integrated browser can also double as a browser preview for the document that you are currently editing.
The Grouped Messages tab in CSE HTML Validator organizes messages by category and separates them from the more important error and warning messages which are normally concentrated in the Message tab.
CSE HTML Validator also checks CSS syntax (including much of CSS3). The Styles tab shows the results of checking CSS syntax. CSE HTML Validator not only checks external style sheets but also checks inline styles and embedded styles in HTML and XHTML documents.
