JQuery implements code sharing for the animation effect of the shutter focus chart (with source code download) and jquery blinds

This is a jQuery-based shutter focus animation. Unlike the previously introduced CSS3 shutter focus animation, it has better compatibility and practicability because it is based on pure jQuery, basically all browsers support this function. The animation for switching the focus chart is a blind animation, but there are also several different shutter animations, so they do not feel monotonous.

Of course, do not forget to reference jQuery library files on the webpage.

We will introduce you to the code sharing (with source code download) for implementing the animation effect of louddb for blinds in jQuery. I hope this will help you!
