Custom CSS in Docker

[Bitbitti]

How do I customize the style of a feed category so that the feeds don't show cover art and have a larger youtube player?
freshrss runs in docker

Have you installed the CustomCSS extension?
How experienced are you with CSS?
Could you please share an example feed and a screenshot? It would help to understand what you mean and speak about the same thing.

hi,i have little knowledge of css.
I would like, that in all the feeds of "lo scribacchino", already selected in the picture, to remove what is pointed by the yellow arrow and enlarge what is pointed by the red arrow

check if it works for you

.content .enclosure {
  display: none;
}

[Bitbitti]

it works perfectly.
I modified the command like this:

.content .enclosure-thumbnail {
  display: none;
}

now how do i enlarge the youtube player?

[Bitbitti]

thank you all for your help,
to enlarge the youtube player, i used the command:
audio, iframe, embed, object, video {
max-width: 500%;
width: 400px;
height: 600px;
}
