Setting a background

By default there is no background on the wiki pages, but several properties allow to customize the background:

• The "background" property in the configuration file or the command-line allows to add a background to the article pages
• The "backgroundOpacity" property allows to specify the opacity of the background image (integer value from 0 to 100)
• The "backgroundColor" property allows to add a background Color or gradient to the article pages. The format of the Color must be an HTML Color ID^[1]
  For example -backgroundColor=#33CCFF
• The "backgroundGlobal" property is a boolean specifying that the background must be set for all pages (default is true)

Note that if the "background" and "backgroundColor" properties are both defined, the "background" property will be used.

Background image

The property is the absolute or relative path of the image used for the gradient (For example -background=my/image/image.jpg). The format of the image can be "jpg" or "png".

You can specify the opacity of the background image with the backgroundOpacity" property (integer value from 0 to 100).

Background color

• You can specify only one color (For example -backgroundColor=#33CCFF). In that case the background will use only one color
• You can also specify a gradient with two colors (For example -backgroundColor=#FFFFFF;#CCCCCC). In that case the background will use a vertical gradient defined with the two colors

Customizing the background

The div.middleWithImage and div.middleForIDXWithImage CSS rules allow to specify how the background is presented. The default is:

   div.middleWithImage, div.middleForIDXWithImage {
     float: left;
     width: 80%;
     padding: 0 2%;
     margin: 0;
     min-width: 400px;
     margin-bottom: 10px;
     background-image: url("Background.png");
     background-position: center;
     background-repeat: no-repeat;
     background-size: cover;
   }      

It is possible to customize the background by overriding these properties in the Custom StyleSheet file. For example:

   div.middleWithImage, div.middleForIDXWithImage {
     background-position: top !important;
     background-repeat: repeat!important;
     background-size: contain !important;         
   }
