>>31230738"An animation" is a piece of media consisting of drawn or computer-generated images displayed in a sequence such that they appear to be in motion.
In the context of the post that you're confusingly attacking, however, "animation" refers to the quality of said images, in terms of aspects such as detail, coloration, background, the fidelity of the "motion" of the images, and other such characteristics.
I hope that's a helpful explanation,
