Since we were using an icon font with no text, screen readers were
announcing things like "Enabled, L", trying to read the icon generated
with CSS.
Using text and replacing it with CSS with an icon solves the problem.
We could also use aria-label, but I prefer using "Yes/No" so the text
can be shown/hidden with CSS. Also useful when using
`save_and_open_page` during tests, since the displayed page will not
have any CSS rules applied.
Out of several existing techniques to hide text [1], we're setting the
font size to 1px in combination with moving the content off-screen
because that way we can override it in the `::before` element.
Just moving the content off-screen has the inconvenient of the content
still being taken into account when calculating the text indentation.
And just using a 1px font would make a 1px-sized square appear when
selecting text, which could confuse users.

Using 10000px means content will be visible on screens with ultra-high
resolution (although I don't think they exist nor will exist anytime
soon).
Having screens in the future with a width of 1000rem is less likely,
since a line with 1000 characters would be pretty much impossible to
read.
Previously the draft mode was a phase of the PB, but that had some
limitations.
Now the phase drafting disappears and therefore the PB can have the
status published or not published (in draft mode).
That will give more flexibility in order to navigate through the
different phases and see how it looks for administrators before
publishing the PB and everybody can see.
By default, the PB is always created in draft mode, so it gives you
the flexibility to adjust and modify anything before publishing it.
Note using `params[:relatable_type].classify` is recognized as a
security risk by some tools. However, it's a false positive, since we've
added constraints to the URL so that paramenter can only have the values
we trust.
This way screen reader users will be notified that the element is the
current one.
I'm not entirely sure whether `aria-current="page"` is more appropriate
than `aria-current="true"`, since it's a general helper which can be
used for any collection of links.
This way we'll be able to apply it to the SDG icon, which is not
included in font-awesome.
Note we're adding a font-icon selector so it's defined before the
admin-menu-icon selector and so in case of conflicting rules the ones in
the admin-menu-icon selector are used.
This way we simplify the HTML and generating similar menus will be
easier. We also improve the experience for screen reader users, who
might have been hearing the icons as text because we weren't using the
`aria-hidden` attribute.
We're still keeping the "icon-" classes for compatibility with CONSUL
installations which might have changed this code.
From a semantic point of view, there's no reason to add a strong
emphasis to the menu items.
Besides, using CSS simplifies the code and is less error-prone. For
instance, the "stats" section didn't have a <strong> tag, and so it was
the only one which wasn't bold.
The planned budget investments redesign includes using icons in some
tables, so we might as well use them everywhere.
The original design used Foundation to show the tooltips. We're using
CSS in order to keep the ERB/HTML code simple. One advantage of using
CSS is we can show the tooltip on focus as well, just like accessibility
guidelines recommend [1]. On the other hand, Foundation tooltips appear
on the sides when the link is at the bottom of the page, making sure
they're visible in this case, while CSS tooltips do not. Neither CSS
tooltips nor Foundation tooltips are dismissable, which might be an
accessibility issue.
Note we aren't changing any ERB files in order to replace links with
icons; we're only changing CSS and one line of Ruby code.

Note the CSS could probably be improved to avoid duplication with other
button style definitions. However, that's fine because we're going to
change the style of the links soon.
For the same reason, I haven't bothered to style every single link the
way it was until now.
In the past we were using some <div> tags surrounding table action
links in order to guarantee these links wouldn't be wider that their
cell's space and wouldn't expand over two lines.
However, while these links didn't expand over two lines, at certain
resolutions the width of their text exceeded the width of the links,
causing part of the text to be outside their borders.
This behavior was also inconsistent: some tables had these <div> tags,
and some tables didn't.
Since we've now introduced the table actions component, the code is more
consistent and we're getting rid of these <div> tags. So now we're again
facing the issue where links could expand over two lines.
Using a flex layout solves this issue and considerably improves the
layout at lower resolutions.
