Plug in constants/variables - See MDL-6798 for details

Information from Urs Hunkler:
|
|
|
|
|
|
More flexible themes with CSS constants: An option for Moodle retro themes and easy colour palette variants.
|
|
|
|
I adopted Shaun Inman's "CSS Server-side Constants" to Moodle: http://www.shauninman.com/post/heap/2005/08/09/css_constants
|
|
|
|
With setting "cssconstants" to true in "config.php" you activate the CSS constants. If "cssconstants" is missing or set to "false" the
|
|
replacement function is not used.
|
|
|
|
$THEME->cssconstants = true;
|
|
/// By setting this to true, you will be able to use CSS constants
|
|
|
|
|
|
The constant definitions are written into a separate CSS file named like "constants.css" and loaded first in config.php. You can use constants for any CSS properties. The constant definition looks like:
|
|
|
|
@server constants {
|
|
fontColor: #3a2830;
|
|
aLink: #116699;
|
|
aVisited: #AA2200;
|
|
aHover: #779911;
|
|
pageBackground: #FFFFFF;
|
|
backgroundColor: #EEEEEE;
|
|
backgroundSideblockHeader: #a8a4e9;
|
|
fontcolorSideblockHeader: #222222;
|
|
color1: #98818b;
|
|
color2: #bd807b;
|
|
color3: #f9d1d7;
|
|
color4: #e8d4d8;
|
|
}
|
|
|
|
|
|
|
|
The lines in the CSS files using CSS constants look like:
|
|
|
|
body {
|
|
font-size: 100%;
|
|
background-color: pageBackground;
|
|
color: fontColor;
|
|
font-family: 'Bitstream Vera Serif', georgia, times, serif;
|
|
margin: 0;
|
|
padding: 0;
|
|
}
|
|
div#page {
|
|
margin: 0 10px;
|
|
padding-top: 5px;
|
|
border-top-width: 10px;
|
|
border-top-style: solid;
|
|
border-top-color: color3;
|
|
}
|
|
div.clearer {
|
|
clear: both;
|
|
}
|
|
a:link {
|
|
color: aLink;
|
|
}
|
