With all the hype over the new HTML standard, it's important to bring the discussion back down to earth. Here are the important facts you need to know about this new HTML specification: HTML5 is the first new version of the specification since 1999—the Web has changed a lot since then.

HTML5/CSS 3 Modal Dialog Box; no JavaScript. Problem Definition Modal dialog boxes (or, in other words, modal pop-ups or "dark-box") represent the quintessential component of the User Interface (UI) design.
