Black background gray secondary navigation menu effect code implemented by js

The example in this article describes the black background gray secondary navigation menu effect code implemented by js. Share it with everyone for your reference. The details are as follows:

This is a js-implemented secondary navigation menu with a black background and gray color, which is compatible with the js css horizontal two-pole navigation menu of IE6 and Firefox. It's quite simple, but very refreshing. The secondary menu is displayed horizontally below the main menu, using the popular Microsoft Yahei font. If you don't want to use this font, you can change it to the default Song Dynasty.

The screenshot of the running effect is as follows:
