Use of Stylesheets

Problem: Use CSS to control the presentation of the page.

Solution: Using CSS stylesheets helps with consistency and centralizing styles, and lowers the overall page size.

Discussion: Many mobile browsers prioritize markup before presentation, loading stylesheets and images last. This sometimes causes markup to appear briefly without styles while the external stylesheet loads. Get around this by adding important styles to the document head alongside using an external stylesheet.
The recommendation is to always use CSS, separated from your markup. This allows you to control the page presentation while decreasing the page size and allowing the browser to cache the CSS for later use.
