hello!! i'll answer new anon things here, sorry i havent been active, school is bmaaa
i'm glad i was able to help you! if you mean text headers, that's a part of the how section (here). otherwise, as far as i know, any variation in text sizes is through fonts. in my "finding fonts" i talk about how to make custom text and for small text i use https://www.google.com/search?q=superscript+lingojam / super or subscript.
if i'm understanding you right, you're talking about formating, which is my "formating rentires on phone and pc" page! feel free to follow up if thats not wym.
para lo básico, revisaría esto y mi sencillo tutorial de rentries aquí :)
for dividers, recolor them the same way you do your graphics, if the color is showing up different, you can try making a specific gradient map to match it as close you can or greyscale the divider first then apply a coloring!
