Basic Theme

Features

• reset css: ensures the styling is consequent amongst all browsers
• uses separate css files for different rendering situations: reset, base, print, handheld, ..., and the regular style.css which is similar to the one used in all other themes
• concatenation and minification ability for the css, js and json files:
  • This is disabled by default, and will need to be enabled in the configuration
  • The IncludePageMeta has been extended to generate URL's to the concatenated version of all css files using the same media tag (if enabled in config)
  • The ConcatenationReader has been created to return concatenated and minified versions of the css and js files
  • This is built to use the list of included css files, last modification timestamps, ... for caching purposes.
  • In order to enable this for any of the existing themes, the theme sitemap must be altered as well
• javascript loading if jquery is moved to bottom of page for fast loading
• uses new dri2xhtml-alt, and everything which is replaced in the theme, is included using the exact same hierarchy, for a good overview
• the rendering of item display and item lists has been completely redesigned
• the browser is no longer determined using the sitemap, but is determined in the page-structure.xsl: this is supposed to be more reliable
