Are Those Tags and URLs OK?

The strength of Web pages as a communications medium is their use of hyperlinks. What makes Web documents less than useless are broken or incorrect links. To avoid this, a variety of tools can help validate Hypertext Markup Language (HTML) documents by checking them for syntax errors and integrity of links. Most HTML editors include such functions, and tools are available on the Web to check documents against the latest HTML specifications (try http:// www.webtechs.com/html-val-svc and http://www2.imagiware.com/RxHTML ). For a tool that checks for links to nonexistent resources, such as pages that have moved, try http://wsk.eit.com/wsk/dist/doc/admin/webtest/verify_links.html .

It's important to test Web pages with several Web browsers to see that they look the way the Web author/designer intended and that all hyperlinks are valid. It can also be important to test with browsers on various platforms to eliminate any incompatibilities. For example, one early version of the BYTE Site looked fine on most browsers except for some Netscape versions on the Mac, where the colors became distorted and muddy.
