While people using screen readers already have keyboard shortcuts to
jump to the <main> tag, there are people who navigate the page with the
keyboard using just the tab key, and for them, this link provides a way
to save time and start reading the main content instead of having to
manually go through all the navigation links every time a new page is
loaded.
Note that we had to add an additional `width: 0` rule because
Foundation's `element-invisible` would apply `1px` and the test checking
for `visible: :hidden` would faile.
Many pages had this tag, but many other didn't, which made navigation
inconsistent for people using screen readers.
Note that there are slight changes in two pages:
* The homepage now includes the banner and the content of the
`shared/header` element inside the <main> tag
* The budgets index now includes the banner inside the <main> tag
I see both potential advantages and disadvantages of this approach,
since banners aren't necessarily related to the main content of a page
but on the other hand they aren't the same across pages and people using
screen readers might accidentally skip them if they jump to the <main>
tag.
So I'm choosing the option that is easier to implement.
Note we're adding a `public-content` class to the <main> element in the
application layout. This might be redundat because the element could
already be accessed through the `.public main` selector, but this is
consistent with the `admin-content` class used in the admin section, and
without it the <main> element would sometimes have an empty class
attribute and we'd have to use `if content_for?(:main_class)` or
`tag.main` which IMHO makes the code less consistent.
The Capybara::DSL monkey-patch is only done on the `visit` method
because it's the only reliable one. Other methods like `click_link`
generate AJAX requests, so `expect(page).to have_css "main", count: 1`
might be executed before the AJAX request is finished, meaning it
wouldn't properly test anything.
Just like we did for budgets, we're doing the same thing in all the
places where we render background images attached by either regular
users or administrators.
This way we correctly render background images with characters like
brackets or quotes.
This way it'll be easier to decide when they should be rendered.
In order to be consistent, we're using the `Layout` module for both
components; previously, the navigation partial was in the `shared`
folder while the footer partial was in the `layout` folder, which IMHO
didn't make much sense.
We forgot to do so in commit d827768c0. In order to avoid the same
mistake in the future, we're extracting a method to get these
attributes. We're also adding tests, since we didn't have any tests to
check that the `dir` attribute was properly set.
A <header> tag is the natural place to have headings.
Since we already had the logo there, IMHO it makes sense to merge both
the <h1> tag and the logo together. We were already doing so in the
devise layout.
From the sceen reader users' point of view, having a link with the text
"CONSUL logo" is a bit confusing, since it seems to imply the link will
get us to the CONSUL logo. Using the organization name as the text of
the link makes more sense.
One thing changes, though. Before this commit, the first thing on the
page a screen reader user would hear about would be the organization
name. Now the language selector and the top links are announced before
the organization name is read. That's fine, since the actual first thing
these users will hear is the content of the <title> tag, which contains
the organization name as well.
We were using a "push" div in order to force the footer to the bottom,
and were using a wrapper with a minimum height and negative margins.
The same thing can be accomplished using flex and making the wrapper
fill the empty space, which in my humble opinion simplifies the code and
makes it easier to follow.
We could further simplify the code by removing the wrapper div or the
footer wrapper, although I'm not sure the benefits overcome potential
inconveniences caused to other institutions who might have custom styles
based on the existence of these wrappers.
They do the exact same thing; however `html_safe` might confuse
developers into thinking it will make the HTML safe. Using `raw` makes
it clear that we're inserting the text without escaping it.
