The Power of Validation
You can now rest easy at night because by entire now validates against XHTML 1.0 Transitional. I had been a bad boy up until now, telling the browser that my page was valid, but in fact not being so. For instance, I was bad and didn’t give any of my images alt attributes so that screen readers could give meaning to the images. Also, I was bad and started ids with numbers instead of alpha characters (a-z and A-Z). Anyway, all of these problems are now fixed and each and every page is valid according to the W3C HTML Validator.
