You might be asking yourself, "What are the benefits of standards-compliant Web site?"

• Accessibility - Because web standards incorporate and support accessibility compliance, a standards-compliant web site is one step closer to accessibility compliance. By making your site accessible to the millions of people affected by disabilities, you can increase your customer base. In many jurisdictions, accessible sites are mandated by law. Accessibility means building a web site that everyone is able to access, regardless of their level of physical or mental ability.
• Device independence - By employing the most recent standards for CSS, you can make it possible for your web page content to be accessed by different browsers and devices - for example, the same web site can be accessed on both a cell phone and the majority of computers.
• Faster loading - Standards-compliant code lowers the file size of web pages , resulting in pages that load faster, giving your users a better experience.
• Lower bandwidth usage - You pay for the bandwidth to deliver your information. You can lower bandwidth costs by reducing any unnecessary information your web site sends to your audience. Studies have shown that using modern, standards-based design methods can reduce the weight of a site by 25% to 50%.
• Ease of maintenance - The separation of content and presentation encouraged by standards allows site-wide changes to be made by editing a single style sheet. Without standards, the same change would have to be made on every page of the site. Furthermore, the use of web standards also promotes standardization among the pages within the site. The standardization of web site pages together with separation of content from presentation makes it easier for web authors to maintain the content on the web site. The content changes are faster and cheaper than in non-web standards compliant web sites.
• Improved user experience - Non-standard code can make it impossible for people using less common platforms, devices or user agents to access your site's content. If your web site conforms to standards then your content is available to all web users (your potential customers).
• More compatibility - A site or application that is written to a standard uses a well-defined technology and can be easily checked for compatibility with other products. Applications developed using non-standard or proprietary code can lock companies into using the application's technology because of the cost and difficulty of finding compatible products and technologies.
• Future Growth - Web standards at all levels are designed to work together in an extensible manner with future growth in mind. Standards-compliance is a sound and sensible way to invest in web development projects with room to grow and adapt to future needs.
