Web 2.0 layout


I’d like to create a registration form something similar to this:

Does anybody know which language mediafire created their registration form with please?

Thank you.

The look is created by HTML and CSS, of course, and the on-page validation behavior by JS. The processing is presumably done with PHP, given that the page has a .php extension.

Thank you! Is the CSS what is changing the colour of the box from white to red when you click in a field and click out?

The color and the little icons are done with CSS. BUT … the new CSS rules apply to the boxes with the help of JS. If the box isn’t filled out properly, JS adds a class of “error” to the input, and then the CSS styles associated with that class apply to the input.
