an addon is a cSS file which adds extra features and / or enhances pre-included features.
since configuration is managed with cSS variables, it obeys all rules of a cSS property
class pairs are defined by adding two classes as a selector. Example: a class pair which has two classes one and two has the selector .one.two. class pairs can have more than 2 classes as well.
channels are like different versions of files. like beta releases, stable releases, older releases etc. channels allow developers to use older versions or see new features before they are released.fluento recommends use of channels whilst creating addons.
we recommend uploading the files in a github repository then using the view raw option. the link opened is the link used in cSS to add the addon.
in the same repository as the cSS file, we recommend using github pages and making the addon website.
