CSS Files
This page helps you understand the different css files used in XWiki, their purpose and content. XWiki skins use several css files to separe the different components of the skin: basic elements, layout, colors, etc. Check this page to learn about the XWiki layout.
Core files
style.css
This is the top level style file. It's purpose is to include all the other files. It shouldn't have any other css in there. It looks like this:
@import "colorsblack.css";
@import "elements.css";
@import "presentation.css";
@import "screenlayout.css";
...
XWiki 16.0.0+ This file is now populated by style.less.vm, which contains in its template all the imports.
Special purpose files
microformats.css
Stylesheet to format the different microformats-enabled pages (user profile, blog, calendar...).
print.css
Formatting for the @media print.
Legacy files
Those files used to be important CSS files used in XWiki. With the move to Flamingo ColorThemes with Bootstrap and LESS, the style structure we use got updated and those files are not in the codebase anymore as of 16.10.0 .
classes.css
Like elements.css, but formats elements having a similar semantic meaning (after all, a class should have a semantic name, and not a random id). As examples: .underline, .hidden, .sep, wikicreatelink, or .heading-1-1. This should only contain general classes (for specific elements see presentation.css). It looks like this:
display: none;
}
.clear, .clearfloats {
clear: both;
}
.none, .hidden {
display: none;
}
...
screenlayout.css
The place where the general layout of the interface is specified. This file should contain rules regarding position, dimension and display mode for the major elements of the interface (header, side panels, menu, footer...).
width: 100%;
padding: 0;
margin: 0 ;
min-width: 760px;
}
.minwidth, .minwidthb, .minwidthc{
width: 720px;
height: 0px;
}
.minwidthc{
width: 438px;
}
...
presentation.css
Refinement of screenlayout.css. This is where borders, margins, paddings are set, font styling for objects not in elements.css or classes.css, along with some specific elements of the layout which are not affecting the general layout (where is the profile picture displayed, how is the comment author displayed, etc.).
.main-content {
margin: 0.5em;
}
...
colors*.css
This is the place where the skin gets painted. Without this file, the skin should be black and white only (except the blue links). Font color, background, border color.
color: #369;
}
ul.xwikiintra{
border-bottom-color: #DDD;
background-color: #EEE;
}
...
elements.css
XWiki 16.0.0+
This file is not available in xwiki-platform anymore, its content has been moved to a few different files:
- type.less for typographic styles, such as title size and generic text mixins.
- Color Themes for admin defined styles, such as text color and font-family.
XWiki <16.0.0
This stylesheet is intended to provide general design rules regarding the html elements. For example, default font size and family for headings, underline for links, etc. You can get a blank version of this stylesheet at this address. It should not provide color properties. It looks like this:
margin: 0;
padding: 0em;
font-size: 90.01%;
line-height: 1.25em;
background: white;
color: black;
font-family: "Arial", "Lucida", "Trebuchet MS", "Luxi Sans", "Helvetica", sans-serif;
}
h1 {
font-size: 1.5em;
line-height: 1.33em;
margin: 0.89em 0;
}
ul {
margin: 1em 0;
padding: 0 0 0 2.5em;
}
...
Deprecated (soon to be removed)
As of 16.10.0-RC1, all the files that were in this section got removed (most of them had their content moved inside a StyleSheetExtension object).
Possibly usable files
if somebody makes the skin wizard
customlayout.css
A dynamic version of screenlayout.css using properties defined in a skin object. Should be parsed by velocity.
customcolors.css
Same, but for colors.
