• Why web standards?
• Efficiency of code:
• Ease of maintenance:
• Accessibility:
• Device compatibility:
• Web crawlers/search engines:
• just by using web standards you will make your site a lot more visible on Google, Yahoo!, etc.
• most sites on the Web still do not follow web standards, and many web developers working today still use bad, outdated practices. “Why?” You ask.
• Lack of education:
• Company policy:
• “I don’t need to learn them!”:
• It will also make your skillset more future–proof, and make you capable of earning more. A lot of companies are requesting skills in web standards these days.
• “It’s too hard to learn!”:
• Standards support in browsers:
• modern browsers all have decent web standards support
• by using modern best practices, you can ensure that users of those browsers will still have a reasonable user experience.

  • Se refiere a los usuarios de los browsers antiguos
• They used to write JavaScript that generated menus etc on the fly (no good for people with JavaScript disabled in their browsers, or people with visual impairments using screenreaders, which get confused by such JavaScript)
