- Common.css mainly contains fixes for annoying glitches in MediaWiki's appearance or behavior, and minor style tweaks.
- There are also various extended standards declared here for the appearance of things like infoboxes.
- The NavFrame class is declared here, which is used by message templates such as the nifty divhide box.
- There's also a modified fix brought over from WP for the annoyingly small text MediaWiki uses for monospaced fonts, which show up when you use <code>, <tt>, and <pre> tags.
- Common.js first looks at whether we're editing a page, and if so, it imports the code from MediaWiki:Common.js/edit.js.
- If we're on our watchlist page, MediaWiki:Common.js/watchlist.js is imported.
- Next, Common.js sets up hasClass(), which is used by the next code, which places the show/hide buttons in those divhide boxes mentioned above. The code after that uses the NavFrame class from Common.css to create the collapsible tables that divhide uses.
- A function called ModifySidebar() is made available for customizing the items listed in the sections on the left of all wiki pages. See Iritscen's custom JS page for a sample usage.
- Parameter 1: The string "add", "remove", or "sep" (which adds a separator line).
- Parameter 2: The name of the section; "navigation", "languages" (not displayed on this wiki), or "toolbox".
- Parameter 3: The display name of the URL you will be adding.
- Parameter 4: The full URL of the wiki page to add (this should allow the adding of external links as well).
- There are also some fixes for IE and table sorting.
