Makes the controls and links inside it match GOVUK
Frontend styles and:
- gives the map container a focus style matching
that for GOVUK Frontend text inputs
- makes it all work in high contrast modes (on
Windows and Firefox)
Note: the focus style for the container is applied
with :focus-visible so only appears when it gets
focus directly, not when it does due to child
elements (like the controls or links) getting
focused. Browsers without support for
:focus-visible get the same styling for all forms
of focus.
To help people understand that broadcasting is not a precise technology,
we have shown the estimate bleed area on the map.
Because people aren’t familiar with the technology a visual only clue is
not enough. So this commit adds a key to the map, which explains what
the different outlines mean.
It also removes the sticky footer from this page to:
- make the key visible on the page
- make people scroll and review the map before they get to the big green
button
- not reduce the size of the map any further
