Implement Inline CSS

Part One Chapter 11


When your mobile web pages require using large CSS block of codes for style, the best practice is to include your CSS in an external file (or several external files). This CSS setup will maximize your mobile web pages' load speed.

In other cases when your mobile web pages only have to use very few lines of CSS codes, it may not make sense to include your CSS codes in external files. It is better to place your CSS codes “inline” – Within your mobile web pages' HTML codes. This setup will reduce the number of http requests to external CSS files and allow your pages to load faster.

Add CSS to Web Pages

When adding inline CSS to your mobile web page, it must be added within the “style” tags in the head section. For example:


body {
  background-color: ffffff;

h1 {
  color: maroon;
  margin-left: 10px;

p, ul, ol{margin-top:0;line-height:180%;}



One disadvantage with this setup is that web browsers will not cache the inline CSS as external CSS files.
