Does inline base64 images make sense in CSS?

Question

css

I saw an old article on Habré, but I'm not sure of its relevance.
And if, nevertheless, there is a sense, then:
If the pictures are small, if they are used often, can they simply be applied through :root{}?

Answer 1

In HTTP/1.x, each file is obtained as a separate request, with the associated overhead of establishing a client-server connection. Accordingly, if hundreds of small pictures are used, then they are either combined into one sprite map, or included directly in css.
