Written by the creator of HomeSite, this latest version of TopStyle expands upon the previous version's style sheet features by adding powerful HTML/XHTML editing. TopStyle's editor provides user-friendly tools which aid in the creation of valid CSS, HTML and XHTML without getting in your way. Time-saving features include the new "Style Upgrade," which upgrades outdated HTML (such as font tags) to CSS with a single click. TopStyle's "Style Checker" checks your CSS syntax and warns of browser-related problems, while integration with CSE HTML Validator and HTML Tidy ensures valid HTML. TopStyle is built for professional web authors who design standards-compliant web sites, but its flexibility lends itself easily to non-professionals who wish to make the move to XHTML and CSS. What's more, TopStyle integrates with popular web authoring tools such as Dreamweaver MX and HomeSite, making it an excellent addition to any webmaster's toolkit.
