This collection demonstrates Greenstone's use of Cascading Style Sheets (CSS) for visual formatting in web browsers. On every page, you can change the style-sheet in effect, to modify that page's appearance. This collection contains the same material as the original Greenstone demo collection.

description1=

A combination of JavaScript and the overriding of GS3 XSL templates in Greenstone 3's global format statement is used by the collection to provide the stylesheet switching. As in some other Documented Example Collections, GLI's Format > Format Features > global can be used to define the additionalHeaderContent template. Doing so overrides the existing additionalHeaderContent template, and appends any specified HTML elements to the HTML header.

description2=

In this case, the additionalHeaderContent specifies the custom collection stylesheet currently active and the JavaScript to facilitate the stylesheet switching when a link is clicked. The create-banner XSL template in the global format statement is also overridden to provide links to the multiple stylesheets within the existing GS3 banner section, and invoke the custom JavaScript when any link is clicked. \n\

If you want to download any of these stylesheets for your own collections, here are links to them\: \n\

GS3 default extra - builds on top of GS3's default style
Blue theme - modifies the GS3 default style for a blue colouring
olive-purple theme - modifies the GS3 default style for a vivid colouring of vine green and purples
None - clears all CSS styling from the current page (needs reload to get the default GS3 style back)

Using a downloaded stylesheet \n\

To use a stylesheet as the default, place it in greenstone/web/interfaces/default/style and rename it to style.css. This will affect all collections.

To use a stylesheet for a particular collection, place it in greenstone/web/sites/localsite/collect/<collection>/style then specify the stylesheet link in the additionalHeaderContent of GLI's global format statement (Format > Format Features > global) as follows\: \n\

<xsl\:template name="additionalHeaderContent"> \n\
    <xsl\:variable name="httpCollection"> \n\
      <xsl\:value-of select="/page/pageResponse/collection/metadataList/metadata[@name='httpPath']"/> \n\
    </xsl\:variable> \n\
    <link href="{$httpCollection}/style/stylesheet-name.css" rel="stylesheet" type="text/css"/> \n\
</xsl\:template>
