Bulky, unmanageable code slows down load times, increases web requests, and degrades browser/user performance.
Enter aTip: the customizable, extremely lightweight tooltip plugin. Weighing in at 1.5KB with colour and style customization you can style any html element, all in different forms and methods. Additionally, the code is well commented, documented and easy to use/modify.
If you want quick, neat and clean pure JS tooltips that support all modern browsers (and most old ones) then aTip is the solution.
This package also includes email based support from Appsource, which includes help with installation should you require it.
