Why Do CSS Animations Flicker on iPhone WebKit, and How Can I Fix It?

CSS Animations on iPhone WebKit Cause Flickering

In the provided URL, users encounter a flickering issue when using CSS animations on the web page. The web developer indicates that they employ the following WebKit animations:

• '-webkit-transition': 'none'
• '-webkit-transition': 'all 0.2s ease-out'
• '-webkit-transform': 'translate(XXpx, XXpx)'

However, these animations result in flickering when the elements snap into place after scrolling. Additionally, when the "Play again" button is clicked, the background of the accessories and purses turns white while the guns are animating in.

Solution:

To resolve the flickering issue, the web developer added the following CSS properties:

• -webkit-backface-visiblity
• -webkit-perspective: 1000

These properties helped eliminate the flicker.

The '-webkit-backface-visibility: hidden;' property prevents the back faces of elements from being rendered, which can cause flickering during animations. The '-webkit-perspective: 1000;' property adds a perspective to the elements, creating the illusion of depth and reducing the flickering effect.

By incorporating these CSS properties, the flicker associated with the CSS animations is significantly reduced, resulting in a smoother user experience.
