Web Standards - HTML Tutorial
What more is there to know about HTML?
HTML can be written in many different ways, and browsers interpret it in slightly different ways as well. In a sense, HTML has many dialects, which is why the same webpage can sometimes look different across browsers.
The World Wide Web Consortium (W3C) is an independent organization that defines and maintains web standards, including HTML, CSS, XML, and more. Companies like Microsoft, Google, Mozilla, and many others participate in shaping these standards, ensuring that web technologies evolve consistently and reliably.
If you’ve done even a little web design, you’ve probably noticed that webpages can appear differently in Chrome, Firefox, Safari, Edge, or other browsers. This can be frustrating and time-consuming. Web standards exist to create a common baseline, so developers can be confident their work will function and display correctly across modern browsers and platforms.
Following standards is strongly recommended: validating your HTML and CSS helps ensure your pages adhere to best practices and reduces unexpected behavior across browsers.
CSS Validator
To help maintain standards compliance, W3C provides a CSS Validator. You can submit your stylesheet to check for errors and warnings, ensuring that your CSS follows the official specifications. You can also use the CSS Portal Validator for a convenient alternative.
HTML Validator
Similarly, you can validate your HTML code to make sure it conforms to W3C standards. Use the HTML Validator to check your documents and catch potential issues early.
