HTML Validators
Even the most experienced HTML writers make mistakes, but with validators to check your pages, you can minimize the damages. HTML validators check your HTML for errors, verify spelling and sometimes grammar, and make sure that your Web sites meet the guidelines.
Best HTML Validators
To evaluate HTML validators I looked for the following features:
- Validate against a defined DTD or schema
- Validate groups of files in a batch
- Validate HTML both online and offline
- Display warnings as well as errors
- Validate HTML, but also CSS, JS, Access, links, spelling, orphans, browsers, and speed
- Price
One Reason to Use Valid HTML
Writing valid HTML often seems like a nuisance, but one reason is if your site is moved into a database, valid HTML or really valid XHTML can become very important. Many CMS programs require valid XHTML because they are based on XML and installed in databases.
