It's probably uhhh not that well, but for temporary it's a good idea I guess.

Would be also a funny experimental thing on how it will get used, since you can actually do subtitles with it, which is going to be interesting.

An URL could be index.html?channel=icdb&notifications&fontsize=30px

has these parameters: width, fontsize, redeemercolor, contentcolor and notifications

Will be added in https://github.com/icecreamdatabase/website/pull/7 instead.
