This article mainly introduces the relevant information about using CSS to make a three-dimensional navigation bar. Friends in need can refer to the three-dimensional navigation bar made by
css. The specific implementation code is as follows:

## Summary:
1. Use an unordered list for the body part2. (1)hover The effect when the mouse is moved up. (2) Question: The difference between::before and :before Simply put, a single colon (:) is used for CSS3 pseudo-classes, and a double colon (::) is used for CSS3 pseudo-elements. w3c specification on css selectors:A pseudo-element is made of two colons (::) followed by the name of the pseudo-element.This :: notation is introduced by the current document in order to establish a discrimination between pseudo-classes and pseudo-elements. For compatibility with existing style sheets, user agents must also accept the previous one-colon notation for pseudo-elements introduced in CSS levels 1 and 2 (namely, :first-line, :first-letter, :before and :after). This compatibility is not allowed for the new pseudo-elements introduced in CSS level 3. Composed of colon and pseudo-element name. The double colon was introduced in the current specification to distinguish pseudo-classes from pseudo-elements. However, the browser needs to support the old existing pseudo-element writing methods at the same time, such as: first-line, :first-letter, :before, :after, etc., while the new pseudo-elements introduced in CSS3 are no longer allowed to support the old ones. Single colon writing.
