Details tag lacks sufficient styling and summary text
Expandable and collapsible text sections, created using the details HTML tag, are insufficiently stylized. This causes the browser to apply its own rules, for instance showing the default text "detaljer" in my browsers, as I run them in Norwegian.
Screenshot of the bottom part of this question:
It's rendered pretty much identically in Safari and Firefox.

The text is not determined by styling, but by a summary tag that is supposed to be inside the details tag, and that is missing in the quoted question.
Example
<details>
<summary>Example</summary>
Content here
</details>
Note that while formally the summary tag is optional in the HTML specification, it also explicitly specifies that a browser-specific legend is displayed if no summary is given. Which in turn means that if you want any control on what is shown as legend, the summary tag essentially is mandatory.
I don't think you can set through styling the default text shown when the summary tag is missing.
I opened the web inspector and made a quick sketch of how I think these sections can be improved. The changes include removing the border, setting a background colour, lowering the weight of the summary font, changing thickness and colour of the dropdown arrow, and setting a border radius. The specific post that's used as an example, fails to include the "Crude example:" in a summary tag inside the details tag, so I moved it down there, too. In case a post doesn't actually specify this, Codidact should automatically insert <summary>Expand content</summary>, or some other appropriate text. Letting the browser automatically set the summary text in the user's own language, is unfavourable.
Without nitpicking on the exact details of how to style these, this is what I came up with:
Currently, the expansion and collapsing actions are an instant snap. It should be updated to smoothy animate the increasing and decreasing height as the section is expanded and collapsed.
The changes include:
<summary style="font-weight: 5;padding-left: 35px;">Crude example:</summary>-
2px solid rgb(60, 70, 75)forborder-topandborder-rightondetails summary::before. -
background-color: rgb(240, 245, 250);andborder-radius: 6px;ondetails
I'd stress that I think this should first and foremost apply to posts, which is what the top-level post is about. It may apply to other elements on Codidact, however, the more basic and barebones version is in place on tag wikis (here, for example), and that looks fine as is.
