Other Options

 Do you  want to obtain the maximum performance on your website? First of all, I suggest simple techniques: put your javascript before closing the html body tag, compress css, compress javascript, compress your html.

If you have a dynamic website, you can use some function about the output buffer to compress the html. It will be more easy to compress CSS and Javascript, because they are more static. If you can do all with HTML and CSS, do it! Use javascript only if you want to obtain some effects. Make your website accessilble to let all users to browse on your website. So if you have done this, your work is finishede at 70-80%!

SOME COMPRESSION TOOLS

HOW ABOUT A CMS?

If you are using a CMS like Wordpress, Drupal or Joomla try to install a plugin or an utility for caching. Reduce the charge of the memory and verify your loading time. I suggest to install the simple tool Page Speed on Google Chrome to analyze your pages and it's very simple to use.

MINIFY CSS

Compress all css in 1 line only code. You can do it with PHP. In this way, you can have your css on your server but when you upload it, PHP will delete comments and all carriage return characters. You can also include small CSS files directly on your page (for example the CSS for the print version). Check out minify on google code.

SPRITE

Google and all serch engines recommend to use sprite images when possibile. But is it real right? I'm afraid to have some problems on different resolutions and different browser if you don't pay the right attention on css values and views. Sure you can take many advantages building and using a single image for your website or application.

CONCLUSIONS

This seems an underrated problem but if you follow my hints above, you can have big results without being crazy searching too complex solutions to compress HTML, CSS and Javascript code. All suggests and comments are welcome!
