The example in this article describes the jQuery implementation of a floating layer plug-in that pops up a closeable layer by clicking a button. Share it with everyone for your reference. The details are as follows:

This is a comic Jquery pop-up layer plug-in adapted from the Bird Js pop-up plug-in. Press ESC to close the window. There is no style by default. You can write styles according to your own projects. The popup layer code is very small, the min version is only 1.15k, and it is worth using because it is small. I hope some netizens can improve it and make her smaller.

The screenshot of the running effect is as follows:

The online demo address is as follows:

The specific code is as follows:
