We’ve had some feedback that relying only on luminosity and position to
differentiate between the ‘will get alert’ and ‘likely to get alert’
areas on the map might not be enough.
We don’t want to introduce another colour because:
- it will make the map look very busy
- not many other colours contrast with the map tiles as well as blue
- relying on colour only to communicate information is also bad for
accessibility
Instead we can make one of the lines a different style. I’ve gone for
dashed on the ‘likely’ line because it looks nice, and gives some
suggestion of a porous boundary.
Implementing this means using CSS border image, because a `dashed`
border (which we still have as a fallback) doesn’t render with
consistent dash sizes from browser to browser. We need consistency to
match the dashes that the map will be drawing (which use SVG not CSS
so don’t have the same problem).
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
We have a reckon that live broadcasts don’t feel prominent,
consequential or active enough on the dashboard.
This commit adds an animated component, similar to an ‘on air’ indicator
in a broadcast studio, or a ‘recording’ indicator on a video camera.
This is one option for addressing our reckon. We shouldn’t merge this
until we have a better understanding of the problem from another round
of user research.
When we have an approval flow, `pending-approval` will be the state a
broadcast is in between being a draft and broadcasting.
This means it is the earliest stage at which a broadcast can appear on
the dashboard, so this commit adds a new section at the top of the
dashboard to display these broadcasts (since the dashboard is in a
reverse chronological order).
Rather than displaying the scheduled time, the extra information shown
is the person who drafted the broadcast, since I reckon you’ll be coming
to this page because they’ve asked you to approve their broadcast.
The styling of the empty message seems to conflict with the hard-coded
widths added by the `dashboard-table` class. So we should only add the
`dashboard-table` class when there is content we need to control the
width of.
Same technique as we use for other pages that update via AJAX.
I’ve split the page up into separate chunks because the DiffDOM library
we use finds it easier to work out what’s changed when there are fewer
elements/a shallower tree.
