It's redundant because there's already a selector `.source nav.sub` with
exactly the same margin-left at line 796.
This selector was added in 1e98fb1027, along
with an identical desktop selector, but that desktop selector was removed in
6a5f8b1aef as part of a larger simplification.
Added in 34bd2b845b
For this to actually do anything, [according to MDN] (and Firefox Dev Tools),
it must be a "flex item", which only happens if its a direct child of a node
with `display: flex` on it. It seems like it could not have worked at the time
when this rule was added, because the only items in `rustdoc.css` with
`display: flex` active were:
* `#help`
This should not contain anything like this.
* `.impl-items h4, h4.impl, h3.impl`
These are all headers, so they shouldn't contain `.impl-items` either.
* `.content .impl-items .method, .content .impl-items > .type, .impl-items > .associatedconstant`
Associated constants and methods definitely shouldn't contain a list of impl
items, and the `.type` class seems to refer to type aliases, which, when
shown inside of an impl, only show a link to the aliased type.
[according to MDN]: https://developer.mozilla.org/en-US/docs/Web/CSS/flex-basis
Nowadays, `display: flex` is a lot more prolific, but `.impl-items` still
seems to only be used in plain block parents:
* If it's not a trait impl, then it's nested below a `<div>` with an id but no
class, added in a5216cf67d. This will be
`display: block`, probably. For example, [vec deref]
* Inherent impls also get a `<div>` tag, for example [vec impl], and they are
also wrapped by their own non-flexbox `<details>` tag.
* If it's a tait implementation, then it's also nested below a `<details>`
container, like [deref cstring].
[vec impl]: https://doc.rust-lang.org/1.63.0/std/vec/struct.Vec.html#impl
[vec deref]: https://doc.rust-lang.org/1.63.0/std/vec/struct.Vec.html#deref-methods-%5BT%5D
[deref cstring]: https://doc.rust-lang.org/1.63.0/std/ops/trait.Deref.html#impl-Deref
Also, this would imply that trait items ought to take up as much space as
possible, pushing everything else to the edge of the screen. If this is nested
directly below the `.rustdoc` container, which has a row basis, that would
be bad.
It was added with e08a84a0c1
(actually, it was called `.methods > .stability` at the time) and was
directly nested that way.
But with the switch to `<details>`, the code has changed drastically out from
under it, to the point where you have to go out of your way to actually get
it to render this way, and the result looks overly-tight and weird alongside
the normal version where this code is not reachable.
Remove unused .toggle-label CSS rule
It was added in https://github.com/rust-lang/rust/pull/44192 but since we moved to `<details>`, we don't use this rule any more.

rustdoc: remove unused CSS `#main-content > .since`
This rule was added (actually, it was called `#main > .since` back then) with cdca084377 and you can see an example of the bug it's intended to fix in <https://doc.rust-lang.org/1.9.0/std/fmt/fn.write.html> by looking at the `1.0.0` version marker.
However, a5a2f2b951 changed it so that `<span class="since">` is always placed in an out-of-band wrapper, so it's never nested directly below `#main` / `#main-content` any more.

rustdoc: remove unneeded CSS `.content table td:first-child > a`
This rule was added in c1c6175e62 to benefit the module items table. However, the module items table stopped using table tags when 6020c79dde switched us over to grid layout.

This class was added to support the function signature [src] lockup. That
lockup was changed in 34bd2b845b to use flexbox
instead, leaving these selectors unused.
Merge duplicated CSS rules
I used the [stylelint](https://stylelint.io/user-guide/configure) tool to check for duplicated CSS rules in order to merge them.

rustdoc: remove incorrect CSS selector `.impl-items table td`
Fixes#100994
This selector was added in c7312fbae4. The bug can be seen at <https://doc.rust-lang.org/1.27.0/alloc/slice/trait.SliceIndex.html#foreign-impls>.
This rule was added to help with a `<table>` that was used for displaying the function signature [src] lockup. That lockup was changed in 34bd2b845b to use flexbox instead, leaving this selector unused (at least, for its original purpose).
rustdoc: remove unused CSS for `hidden-by-*-hider`
This CSS seems to have become obsolete with the move to `<details>` tags,
and its corresponding JavaScript was removed in aee054d05d
rustdoc: remove unused CSS for `.variants_table`
Continuation of #100938 and #101010. This rule was added to support the old, table-based style for displaying enum variants, which are now displayed using headers and paragraphs.

Resolves all of issue #93240
Reproduces a similar change as #99086, but with improvements
In particular, this PR inlcludes:
* redesigning the crate-search selector so the background color matches its surroundings
* decrease the font of the dropdown menu to a reaonable size
* add a hover effect
* make the color of the arrow theme-dependent, using a surrounding div, with :after pseudo-element
that can then be transformed using CSS filters to approximate the desired color
* fix the text "in" to match the title font
* remove the "for xyz" in the "Results for xyz in [All crates]" title when
searching for search term "xyz"; you can already see what you're searching for
as it's typed in the search bar!
* in line with #99086, handle super-long crate names appropriately without a long <select>
element escaping the screen area; the improvement is that we also keep the title
within a single line now; uses some flex layout shenanigans...
* the margins / paddings are adjusted so the selected label of the <select> fits within
the rest of that title nicely; also some inconsistency in the way that Firefox renders
a <select> with "appearance: none" (roughly 4px more padding left and right of the text
than e.g. Chrome) is worked around, and it now produces a result that looks (essentially)
identical to Chrome
* the color of the help menu and settings menu border in light theme is made to match with
the color of the corresponding buttons, like they do (match) in the ayu theme
* the casing of "All crates" changes to "all crates"
* the new tests from #99086 are temporarily disabled, until they can be adapted later
this change removes some interactive elements in `@media print` form.
more specifically, it removes the source links, the expand/collapse toggle buttons, and the `#copy-path` button.
it also adjusts some spacing and removes the `.top-doc` description completely if it's currently collapsed.
