Self-answered and possibly duplicate. Please see first answer <3

title is so freaking dumb that please someone fix or suggest me an alternative title.

What I want is basically this:

With https://ctan.org/pkg/tcolorbox I only managed to achieve one singular box that I could split in half with horizontally but that is it. I can't replicate a color box like this, even a black/white one. I don't know if I understand this correctly:

enter image description here

If yes or not, how can I make a layout like this?

My furthest attempt:

\newtcolorbox[auto counter,number within=section]{theorem}[1]{
    title={\textbf{Theorem~\thetcbcounter: #1}},

\section{example box}
\begin{theorem}{example theorem}
  \tcbsubtitle{example theorem cont.}


which is. literally nothing.

enter image description here

which summarizes my latex skills. help :(

This is not for commercial or any serious book writing I just want my notes look kinda shiny.

    Why don't you just use a description list for the stuff inside. E.g. \usepackage{enumitem} \newlist{problem}{description}{1} \setlist*[problem]{leftmargin=2.5cm,labelwidth=!}
