So we should always avoid doing anything with JS, especially with Element.style. What this property does is add inline style="" attribute to the element, which causes trouble with secure CSP rulesets and causes problems when users try to override our styles.

What value do we not know that we need to perform calculations in JS to get?

I know, but I did it in JS to show this is possible at least.

I wrote what I need to do in #500 (comment)

Do you know how to do that with pure CSS? 🤔

In CSS this seems like it should just be addition. If we're mixing units, we should change them all to em so that the math is just a simple line-height + margin-bottom + margin-top + padding-bottom + padding-top. The header height should be static, we set the font size and don't allow wrapping, so there shouldn't be guessing there either.

What value do we not know that we need to perform calculations in JS to get?

This isn't clear to me still, so maybe I'm missing something here.

I need to calculate the main.margin-bottom's property based on the header.height's property. How I can do that in CSS?

header.height is not static since it will be based on the container where the theme author inject the <readthedocs-flyout> element. How I can get that value with pure CSS?

We don't need to calculate it because we should know this value.

header.height is not static since it will be based on the container where the theme author inject the element.

This doesn't seem correct. If the parent element is 10em, we get this effect if we try to fill vertical space with 100% height:

We instead want the header to be static height, and derived from font-size. We should be able to determine the value needed for margin-bottom just by math based on this.

Ah, I thought we wanted height and width to be dynamic and based on its container. If we want a fixed height, that should be easier to calculate, yeah.

OK. I added .container.closed { height: 2.5rem } and kept the .container { height: auto } so it grows accordingly when it's clicked.
