Front-end - How to solve the background problem by merging multiple css addresses with nginx?

Question

Node+Nginx project, the page uses http://cdn/project1/a.css, pro... such an address refers to css,
Each css may have a background with a relative path, such as background :url(./images/logo.png), after merging, the image path will report an error. Is there any way to solve it?

Answer 1

1. Use absolute paths if possible

2. If you cannot use absolute paths and cannot mix css from different directories, you can call them separately

   http://cdn/??a.css
   http://cdn/project/??1.css,2.css

3. Build the same environment locally for testing, apache also has the concat component

Answer 2

The relative path of the css file must be obtained based on the current css file. Just hang the corresponding pictures in the relative position on the cdn.
