I found a nice tutorial on forms today at work, while building a client’s website (who, most obviously, needed a form). Interesting finds were the <fieldset> and <legend> tags, which help visually separate different categories of information. Having done a research paper on information graphics, those pieces of markup lit a smile. Another bit of awesomeness, the fieldset tag can be styled using CSS.
And also, check out the <label for=""> markup. They allow you to click on the word as well as the radio button (or check box).
If you have any other information about forms, please share.
