The example in this article describes the implementation of the closeable countdown ad special effects code using jquery. Share it with everyone for your reference. The details are as follows:

This is a countdown ad similar to the one at the beginning when playing a video. You can only see the video content after the ad time. It is a small JS ad code with a close button in the upper right corner. The remaining time of the countdown is displayed in the upper left corner. Run the jQuery code. Comprehensive implementation, web page special effects that combine CSS and HTML are compatible with all mainstream browsers. This effect is compiled from the portal website. Hope you all like it.
