If you want to totally stellar websites, consider the HTML Editor your best friend. You'll learn the links with resources like the comprehensive tag reference and vibrant website themes. And for those of you who like to be on peak of the latest and greatest web design developments, we have four words: HTML5 and CSS3 support.
With valid website code, your pages display correctly in different browsers, work better with CSS, and are more accessible for disabled users and search engines. There's also the happiness that comes from knowing you're doing things right. That's why the HTML Editor comes with three different tools to correct human error and ensure that you're using valid code.
A comprehensive Tag Reference section puts the correct tags right at your fingertips. Code Completion automatically suggests tags as you type them, preventing unclosed tags. Last but not least, a built-in validation tool allows you to check your code using W3C standards for perfectly valid pages every time. Whether you are creating websites in HTML 4.01, XHTML 1.0, or HTML5, these tools have you covered.
