This article mainly introduces the sample code of CSS3 to achieve shock wave effect. The editor thinks it is quite good. Now I will share it with you and give it as a reference. Let’s follow the editor to take a look, I hope it can help everyone.
Recently, the following shock wave effect will appear when clicking many browser buttons. Out of curiosity, I studied and implemented this effect by referring to the information on the Internet.
Implementation ideas:
Observe that the wave changes from small to large, and the css3 attribute changes involved include width, height, left, top , opacity, first realize the shock wave layer through pseudo-class, and at the same time, you need to set the center point position before and after the shock wave (a little mathematical knowledge is involved here: draw a picture to calculate the position of two points), and finally set transition-duration: 0 to achieve instantaneous changes, ps learning You can use a:active to simulate the mouse click effect
Simply draw the following picture (very easy):
Implemented code:
