Your CSS files are smaller and simpler.
Explanation:
External stylesheet are used in HTML pages to keep the HTML content and its styling separate. When using external stylesheet all the style rules are defined in CSS files and HTML files only contain the HTML code.
By using external style sheet,
- One can make HTML code smaller and simpler.
- One can use the same stylesheet in multiple HTML pages and thus provide styling to multiple pages.
- With external stylesheet one can alter the single stylesheet code and its effect can be seen on all pages which are using that stylesheet.
