Fixing the "sticky hover button" problem on touch devices

The Problem with Buttons

• pressing a button on a touch-capable device invokes a "hover" style effect, but the hover effect does not go away until something else is touched
• buttons on a touch-capable device don't change visually when pressed or released

The Solution

sticky-hover-fix eliminates these problems in the following manner:

1. determines if the current device is touch-capable; if it is:
2. removes all CSS style rules containing both '.btn' and ':hover'
3. adds 'focus' and 'active' classes to button when touched
4. removes 'focus' and 'active' classes from button when touch ends

Requirements

sticky-hover-fix works with all Bootstrap button classes, with no CSS changes needed. For non-Bootstrap buttons, the following must be true:

• all buttons must be assigned the class 'btn'
• at least one of the '.focus' and '.active' classes must be defined

Demo

A live demo is available at terrymorse.com.
