This is not the right place to post this, you should use !lemmy_support@lemmy.ml. About your question, the frontend source code is here (in Typescript).

I’m trying to do a redesign with a new CSS style, but I ran into the problem that the preview images of the post are loaded as a size of about 256 by 256, this ruins all my plans.

I would also like to add some small excerpts under the title of the post.

By the way, maybe you already have ready-made developments or at least advice on where I can find the main page file?
