Note taking in form of questions/anwser
I among others love to use active recall method for studying the content of my notes. Currently, I use VSCode to write questions and answers in the markdown file in the following form:
<details><summary class="question">Define vector 3D product of A and B</summary><span class="answer">
$\vec{A} \times \vec{B} =
\begin{vmatrix}
\vec{i} & \vec{j} & \vec{k} \\
a_{1} & a_{2} & a_{3} \\
b_{1} & b_{2} & b_{3} \\
\end{vmatrix}$


</span></details>
This makes the studying process a lot simpler as single click reveals the answer. Markdown goodies are also not compromised. Latex, images and other things can be rendered inside the answer.
With <span> it’s currently possible to render markdown in Obsidian which is really nice. It would be superb if that <span> (answer) could be wrapped by <details> (question)
