Westciv today announced the release of Style Master 4.5, the latest update to its CSS (Cascading Style Sheet) editor. The company says this release “builds upon our unique design features like “X-Ray,” innovative online document previewing (you can actually use online documents to preview your CSS while you work on it), WYSIWYG editing, and hand coding power tools, with a new set of debugging tools, to help you quickly spot invalid CSS, work out exactly which CSS is styling what parts of your page, and even determine which parts of your CSS aren’t used anymore.” Style Master is priced at US$59.99 (half price for students and teachers at $29.99), and is available in a 30-day demo version.
