How to include CSS in an HTML document
Article Introduction：There are three common methods for introducing CSS in HTML documents: inline style, internal style sheet and external style sheet. 1. Inline styles are suitable for temporary modification or debugging, and are implemented by adding style attributes to HTML tags, but are not conducive to maintenance and unified management; 2. Internal style sheets are implemented by adding tags to them, suitable for small websites, with concentrated styles and no additional files loading, but they will be repeated when multiple pages are shared; 3. External style sheets are recommended, storing CSS in independent files and referenced through tags to separate HTML and CSS, which is convenient for maintenance and sharing of multiple pages. When using it, you need to pay attention to the correct path, tag location and browser cache issues.
