This Chrome plugin changes the opacity of web pages with a single line of jQuery. Eventually the extension will be plugged into my python script, which will return a dynamic opacity value based on the number of hops in that webpage's traceroute.
It follows the basic Chrome extension pattern of being made up of a manifest.json file (containing metadata) and a .js file containing the actual code. In this case, jQuery is also stored locally in jquery.js.
contentscript.js
$("body").css({ opacity: 0.2 });
manifest.json
Note that jQuery is stored locally as jquery.js, and this file points to the actual code which is stored in contentscript.js:
