A small modification of the theme.

With your permission, I will post a small modification.

:root {
 --base-spacing: 27px;
 --font-size-post: 17px;

* {
    scrollbar-color: #b3b0a7 transparent;
    scrollbar-width: thin;
 }

 #content-wrap#content-wrap .post .title {
 font-size: var(--font-size-main,16px);
}

#content-wrap#content-wrap :is(.cdm[data-article-id], .hl) .title {
  font-size: var(--font-size-main,14px);
}

#content-wrap#content-wrap #headlines-frame {
 padding:var(--base-spacing)calc(var(--content-spacing,(var(--base-spacing) + 4px)))5 calc(var(--content-spacing,(var(--base-spacing) - 15px)));
 transform:none;
 }

body.flat.ttrss_index #main {
  font-size: var(--font-size-main,15px);
}

body.ttrss_main #feeds-holder #feedTree .dijitTreeNode .dijitTreeRow .counterNode {
 font-weight: 700;
 font-size: var(--font-size-tiny,10px);
}

#content-wrap#content-wrap .post :is(.header, .content) {
  padding: calc(((var(--base-spacing) + 2px)/2))calc(var(--content-spacing,(var(--base-spacing) - 10px)) + 1px)calc(((var(--base-spacing) - 5px)/2))calc(var(--content-spacing,(var(--base-spacing) - 2px)) + 15px);
}
}

I don't know what words to describe it, but I like it better this way))
