Modal dialog box (a.k.a. modal pop-up or "dark-box") implemented exclusively via HTML5/CSS3 features without any Javasript. Could run in any modern browser even with client scripting disabled.
Modal dialog boxes (or, in other words, modal pop-ups or "dark-box") represent the quintessential component of the User Interface (UI) design. Web applications typically implement such functionality through the client-side Java scripting, but this option
could be disabled on the client machine, negatively affecting the functional integrity of the application.
Entire web application is encapsulated into a single .htm file (see downloadable attachment). It demonstrates the concept and sample implementation of modal pop-up boxes via HTML5/CSS3 styling. In addition to the modal dialog box functionality, this web application
contains a plethora of aesthetic enhancements, pertinent to modern RIA concept, achieved exclusively via novel HTML5/CSS3 features like the following:
- Rounded corners (works in FF/Chrome/Safari/IE9)
- Box shadows (works in FF/Chrome/Safari/IE9)
- Color gradients (works in FF/Chrome/Safari)
- Text shadows (works in FF/Chrome/Safari)
- Text rotation (works in FF/Chrome/Safari)
Note: IE9 still has some issues with rendering color gradients and text rotation.
