This article mainly introduces jQuery to implement the mask function that is compatible with IE6, and analyzes the layout, style and function implementation techniques of jQuery mask layer in detail. Friends who need it can refer to it. I hope it can help everyone.

The most streamlined and powerful jQuery mask layer effect.

When the browser changes size, the size of the mask layer will change accordingly.

The dialog box above the mask layer can change with the scroll change, that is, the dialog box is displayed in the center of the browser.
