The benefits are the same as the css genie.

3. Use external css.

External css can be cached by browsers and is easy to maintain.

4. Put css in head.

Loading with import pages is slow. And the loading order in IE may not be the same as expected, which will directly lead to display problems.

For example, using margin instead of margin-top and so on.
