Other Guidelines
Avoid, if possible.
Use text length for calculating the amount of time the toast remains on screen: 3 seconds plus 120 milliseconds per character.
Do not rely on hover to dismiss
If you are using color to flag different modes, provide text that conveys the mode as well (warning, info, danger, etc)
Do not load on page load.
Always display toast in same location.
