Below you will find a list of recommended best practices that will make your web pages more accessible:
- Avoid DHTML menus, if used provide a method to switch to alternative menu formats
- Use device-independent event triggers like "onFocus", "onBlur" and "onSelect" rather than user interaction-level triggers like "onmousedown" or "onclick"
- Provide controls to pause, stop or restart timed event
- Provide alternative content using <NOSCRIPT></NOSCRIPT> tag for when scripting is turned off
