:active Pseudo-Class in Mobile Safari: A Troubleshooting Guide
In the realm of CSS, the :active pseudo-class is commonly used to alter the appearance of an element when it is being activated by the user. However, when dealing with tags in Mobile Safari (iOS devices), this functionality may encounter glitches. The tap interaction fails to trigger the :active styling.
Understanding the Issue
Mobile Safari employs a delay mechanism before registering user taps on touchscreens. This delay aims to prevent inadvertent taps from triggering actions. Consequently, the :active styling is never applied because the tap event is not immediately captured.
Solution: Circumventing the Delay
To overcome this issue, we can leverage the ontouchstart attribute on the
element. By adding this attribute, we indicate that touch events should be monitored.<body ontouchstart="">
...
</body>
With this modification, Mobile Safari will immediately register touch events, triggering the :active styling as intended.
Alternatively, developers can utilize "Fastclick," a JavaScript library specifically designed to enhance the touch event responsiveness on various devices. By incorporating this library, the :active pseudo-class will also function seamlessly.
