Create a Web Animation

I require a single page HTML5 toast animation with sound and, text banner. The idea is to show a customizable (by get/post parameters) "congratulations" text message in a "Tadaaa!" fashion with an animation. - Page must include a html text message in center. This text message cannot be an image, however, its properties and appearance can be customized to the full extend of HTML5 and CSS3 capabilities. No coding on your part is required, just put a placeholder text on the page (of course any javascript you use for the animation needs to be included). - At load of page, an animation should start, displaying the text and various graphical elements. This animation should last about 5 seconds total, with minor looping elements around the page. Like, text rolls in, tadaa sound up to 5 seconds, then main animation comes to a stop but baloons around have a looping "swinging with wind" animation. - The style of the animation I had in mind has a disney-toon-like theme, baloons etc, but this is up to your imagination. - Considering many screens today use a 1366x768 display, your work cannot exceed this size. The idea is to have the user see the entirety of the page without having to scroll down. - You may use license-free clipart you may find, but no licensed material. - Attached is a basic example without any anymation I put together while writing this. Obviously you are the artist, not me. Its only purpose is to aid in understanding the concept.
