The example in this article describes the JS implementation of a Weibo-like closeable pop-up layer effect. Share it with everyone for your reference. The details are as follows:

Here is a really good JavaScript web page pop-up layer recommended to everyone. The Weibo-like JS pop-up layer can be closed and pops up only after clicking the button. It can be made into a web page customer service or the like, such as displaying this on the right side of the web page. When the button is clicked, the layer will be expanded and the customer service QQ will be displayed. The effect is still very good!

The screenshot of the running effect is as follows:

The online demo address is as follows:

   1、在代码状态下使用[html][/html]可以贴“代码运行”的代码。并禁用发帖左侧的 URL 识别和标签解析<br />
   2、技术版面请勿灌水。特别受欢迎的主题可以顶一顶，但是请接受版主的定期“擦水”，这是为了减少技术讨论区出现的无效信息。<br />
   3、如需要收藏主题，请使用主题右上角的链接，还可以推荐给论坛里的朋友。<br />
   <b>此方法简单，自适应内容高宽，易方便改风格。</b>
