CitationStyleMarker adds "CS1", "CS2", "CSVAN", or "CSLSA" beside citations to show their style with an optional toggle.

• Add the following to your common.js or your skin.js:

importScript('User:BrandonXLF/CitationStyleMarker.js'); // [[User:BrandonXLF/CitationStyleMarker.js]]

• Alternatively, use the following instead of the above:

mw.loader.load('/w/index.php?title=User:BrandonXLF/CitationStyleMarker.js&action=raw&ctype=text/javascript'); // [[User:BrandonXLF/CitationStyleMarker.js]]

• To install on other wikis (for instance, globally in your global.js on the Meta-Wiki), use the following code:

mw.loader.load('https://en.wikipedia.org/w/index.php?title=User:BrandonXLF/CitationStyleMarker.js&action=raw&ctype=text/javascript');

• After installing reload the page and clear your cache

Optionally, add any of the code snippets below to the JS file you installed the script in (eg. your common.js file) to change the settings for this script. For best compatibility, put them above the code that is used to load the script.

• window.CSMarkerMode = 'always'; – Always enable the script and do not display add a toggle to the toolbar
• window.CSMarkerMode = 'enabled'; – Enable the script and add a toggle in the toolbar (default)
• window.CSMarkerMode = 'disabled'; – Disable the script and add a toggle in the toolbar
• window.CSMarkerMode = 'both'; – Enable the script and add a toggle in the toolbar when at least two different types of citations are present.

Comments are welcome on my talk page, be sure to indicate that you're talking about this script in the title. I would really like any suggestion to make the script run better.
