This cleans up the CSS, reduces the number of different colors and special settings we use.
It increases contrast so we now pass WCAG AAA (according to chromium), and switches to css variables for colors to make dark mode simpler to implement.
* docs: Add "Writing your own prompt" doc
* Remove a space from the "output"
* some teensy adjustments
* Address feedback
* envvar one more PWD
* More html warning
Hyphenation in our documentation is aggressive, even to the point of caus-
ing options themselves to be broken across lines. This makes the document-
ation hard to read, especially when you have an option like `string colle-
ct` which gets a weird hyphen.
Remove the hyphenation from the CSS.
Unlike before, this doesn't force the number to be on the same line as
strongly, that's fine.
So short footnotes look like
-------------
[1] Some text
-------------
Longer footnotes may look like
--------------
[2]
Some more text
--------------
The "Warning:" on the warning (in index.html#default shell) wasn't in
the line with the text, the features list had more padding and some
headers were smaller, some table stuff
This has required workarounds a few times, plus if it changes it might
break our theme. See e.g.
4712da3eb1e27456df24a6d484836e85522036f5
So we import the rules we *use* and throw away the rest. Note that
this might still have rules that are no longer necessary - e.g. some
that are required to work around sphinx bugs would still be left.
It could benefit from some cleanup and simplification, and from
switching to a flex layout instead of the 230px hardcoded
sidebar - sphinx tried that, but it doesn't really work with our
narrow layout, so we disabled it again.
This is broken in narrow screens - the sidebar shrinks to unusable
proportions but still stays.
So instead we go the *other* way, force the left margin and undo the flexifying.
(again we should really stop relying on sphinx' css)
Sphinx 5.0 makes the document div a flex container, which clashes
badly with the margin that earlier versions need.
So we remove the margin and flex the div ourselves, which should work
with either.
It's time we make this freestanding - these changes are annoying.
Otherwise this does "justify", which in bad cases can spread the text
over the width of the whole line, leaving awkward space between words.
This looks something like
```
The main file is ~/.config/fish/config.fish
```
The current python docs theme also left-aligns.
Unfortunately the normal font families like "sans-serif" and
"monospace" are basically broken because the browser defaults are
decades old.
TODO: Inline code is barely distinguishable.
Adding the underline in the list of sections makes them bleed
together, making it hard to discern where one ends and the other
begins.
In the body of the text we don't have that issue - multiple links are
rarely next to each other.
Fixes#8439
This uses a bit of javascript to add copy buttons, so you can directly
copy all the code in a given block to the clipboard!
For codeblocks without prompts, it just copies all the code, for
blocks with prompts, it copies all the lines after prompts, under the
assumption that that's the code to be executed.
It would give you *all* the lines, so the output wouldn't be
interleaved like it is in the html, but good enough.
The buttons appear on hover, so they aren't usable on phones, but
since you won't really have a clipboard on phones and I have no idea
how to make them not always in front of the text otherwise: Eh.
I'm not in love with the javascript here, but it'll do.
Especially in dark-mode this was often too close to the background.
Should make it easier to read.
As always, colors not checked for artistic merit for I have none.
This set "clear: both", which resulted in code blocks sometimes being
pushed down a lot, resulting in weird empty space.
Just undo it, I have no idea why it's there, presumably it makes sense
with sphinx' stock theme?
