Visual AidsVisual aids (on the View menu, click Visual Aids, and then click Show) help you see empty or invisible elements and elements with hidden borders. You can also use visual aids to find elements that have hidden or invisible styles, as well as ASP.NET controls that aren’t visible on a page. Finally, you can use visual aids to see which tags are used around specific content, and you can see the size of margins and padding around your tags.
CSS ToolsExpression Web provides you with a comprehensive set of tools to create, apply, and manage styles and cascading style sheets. These tools include:
Web Standards and Expression WebWeb standards refer to a list of standards or recommendations established by the W3C for creating and publishing Web sites. These standards are generally agreed to be best practices for Web site development and take into consideration such issues as accessibility for people with disabilities, cross-browser compatibility, and platform compatibility. When Web sites conform to W3C standards, they are more likely to be accessible to a greater number of people using diverse devices, browsers, and platforms. Expression Web features state-of-the-art tools for ensuring that your Web sites are compliant with these standards. As accessibility and Web standards have become more important, the way Web sites are built has changed as well. How your content is marked up—the HTML—is as important as the design (the presentation or display) of the site. Part of the current recommendations for XHTML provides guidelines for how HTML code is written and structured, and for using CSS, which separates the presentation from the HTML. When you separate content from presentation, it is much easier to create Web sites that are accessible not only to people with disabilities by adhering to the Web Content Accessibility Guidelines (WCAG), but also to other form factors, including printers, handheld devices such as cell phones and PDAs, and across different browsers and browser versions. With a standards-compliant site and multiple style sheets, you can more easily provide alternative designs for other form factors instead of having to try to maintain several different versions of your site. DOCTYPEsAt its core, creating a standards-compliant site essentially means making sure that your code conforms to a specific set of rules identified by a specific DOCTYPE. The DOCTYPE declaration—a line of code at the top of the HTML document—declares which set of rules your HTML is designed to follow. There are DOCTYPES—rules—for HTML as well as XHTML, and for the strict as well as the transitional application of those guidelines. The following are examples of DOCTYPE declarations: DOCTYPE declaration for HTML 4.01 Transitional DOCTYPE declaration for XHTML 1.0 Strict For more information on DOCTYPE declarations and which one to choose, see Fix Your Site with the Right DOCTYPE. Once you’ve decided which set of guidelines that you want to follow, you can then test, or “validate,” your site to see how closely they follow the guidelines. A compliant Web site is one that passes the validation test. An accessible Web site is one that follows the accessibility guidelines. Expression Web has built-in validation tools, code error notifications, and more to help you create a Web site that follows Web standards.
