As illustrated on the W3C Schools site, once you know how to make a stylesheet you can import as many as you like into a document, and make the power of CSS work for you.
Pioneered and championed by expert designers and bloggers such as Jeffrey Zeldman, the demand eventually resulted in the formation of the WorldWideWeb Consortium, or W3C.
While this added code is generally beneficial, and in most cases, necessary for W3C compliance, the automatic inclusion removes a level of control from the developer.
Their standards based approach creates w3c compliant pages that are easy to read and download fast for dial-up users.
As the W3C makes standards more universal, HTML still has a place in every designer's toolkit.
The built-in validation tool allows the user to check their code against the W3C standards.
More HTML tags for text formatting can be found on the W3C website.
