Understanding the CSS Files
CSS is used both for layout and for styling, the more you learn about CSS the easier it will be for you to create nice looking skins for mojoPortal.
The CSS Files
As of mojoPortal content management system 18.104.22.168, we combine the CSS files into one request for better performance. The style.config file is the list of files to include and in the correct sequence to include them. So you can organize your css into as many or few css files as you like. You can also include comments in your CSS files without worrying about it adding to the size of the files as the comments will be removed as part of the combining and minifying of the CSS.
In the included skins we typically have the following css files:
IESpecific.css is a supplemental stylesheet that is only included when the browser is Internet Explorer version 6 or less
IE7Specific.css is a supplemental stylesheet that is only included on the page when the browser is Internet Explorer 7 or greater
If you need IE Specific CSSfiles for IE 8 and/or IE 9, you can drop in a file named IE8Specific.css and set IncludeIE8="true" on the<portal:IEStyleInclude control in your layout.master file. For IE 9 drop in a file named style.ie9.css and set IncludeIE9="true"
Additionally, the style.config usually includes some common css files, for more information see Understanding Style.config.
You can quickly become a CSS guru by understanding selectors. To get up to speed quickly on CSS Selecotrs see the article CSS - Its All About Selectors.
