Graded Browser Support
To ensure that everyone enjoys the best possible experience using Launchpad, we've adopted and adapted Yahoo's Graded Browser Support chart. This has also been inspired by jQuery's browser support matrix.

Grades of Support
We use three grades of support:
- A-Grade
These browsers are fully capable of handling modern web standards. JavaScript is used to provide a fully enhanced experience.
- C-Grade
These browsers have significant problems with modern display techniques or functionality. For these browsers, the page provides core functionality, without JavaScript enhancement.
- X-Grade
- Assumed capable, these browsers are presented with the A-grade page, but we do not explicitly testing them. If an X-Grade browser is shown to be incapable — if it chokes on modern methodologies and its user would be better served without decoration or functionality — then it is considered a C-grade browser.
