SlionSkin CSS Cookbook

Questions and answers on how to customize the default look of Foswiki for your own needs, using style sheets. For configuring page elements, see SlionSkinCustomization.

First Read: How to modify SlionSkin styles

SlionSkin uses 3 style sheets (attached to SlionSkin):

• layout.css - the positioning of main page elements (blocks), widths and heights
• style.css - fonts, sizes, margins and paddings
• colors.css - border colors, text colors and background colors

When customizing your Foswiki installation, you can either choose to completely rewrite all css styles, or to selectively override some styles. The latter option is by far less time consuming, but all depends on your graphical wishes.

Changing the color scheme

Have a look at SlionSkinColorSettings.

When you need lots of graphic changes: Rewriting CSS

• Create a new topic that will contain your new CSS files
• Attach 3 new style sheets to the topic
• Point the CSS preference settings in System.DefaultPreferences or Main.SitePreferences to your new files:

      * Set FOSWIKI_LAYOUT_URL = %PUBURLPATH%/%SYSTEMWEB%/YourNewTopic/layout.css
      * Set FOSWIKI_STYLE_URL = %PUBURLPATH%/%SYSTEMWEB%/YourNewTopic/style.css
      * Set FOSWIKI_COLORS_URL = %PUBURLPATH%/%SYSTEMWEB%/YourNewTopic/colors.css
 

When you need to make small adjustments: Adding to existing CSS

With CSS you cannot remove already defined classes, you can only add to it, or override existing styles.
Overriding default CSS is done with 3 preference settings: USERLAYOUTURL, USERSTYLEURL, USERCOLORSURL.

• Create a new topic that will contain your new CSS files
• Attach 1, 2 or 3 new style sheets to the topic, dependent on your CSS setup (if you don't change much, you might as well put everything in one CSS file, layout, margins and colors)
• Point the CSS preference settings in System.DefaultPreferences or Main.SitePreferences to your new files (below the TWIKIXXXURL preferences):

      * Set USERLAYOUTURL = %PUBURLPATH%/%SYSTEMWEB%/YourNewTopic/layout.css
      * Set USERSTYLEURL = %PUBURLPATH%/%SYSTEMWEB%/YourNewTopic/style.css
      * Set USERCOLORSURL = %PUBURLPATH%/%SYSTEMWEB%/YourNewTopic/colors.css
 

• If you use only little CSS and you've only attached one file, write:

      * Set USERSTYLEURL = %PUBURLPATH%/%SYSTEMWEB%/YourNewTopic/style.css
 

Instead of setting these preferences in System.DefaultPreferences or Main.SitePreferences, you can set these in your home topic, or in any other topic. Setting style URL preferences in:

• System.DefaultPreferences or Main.SitePreferences: the style is visible for all users, site-wide
• WebPreferences: the style is visible for all users in one web
• Home topic: the style is visible for that one user when viewing the site
• Some other topic: the style is only visible in that one topic

User styles are always loaded after Foswiki styles.

The rest of this topic shows examples of small CSS changes.
