We could do something with Javascript to only show the selected template. For
now this is something that works without Javascript.
This means we can put off getting the build and testing pipeline for Javascript
set up, which is a bigger and more unknown piece of work.
Since GOV.UK Elements is versionned now it makes sense to bring it in as a
dependency. This enforces a separation between what generic stuff we’re using
from Elements and what is specific to our app.
The benefit is that when the generic stuff changes it will be easy to bring
those changes in.
This commit also bumps GOV.UK frontend toolkit to the latest version (v4.5.0).
This commit adds some stubbed data for the pages. The structure of the data
is just a proposal, but it gives the templates something to work with for now.
As a first guess placeholders can be added to messages with the
`((placeholder))` syntax.
This commit adds a Jinja template filter to convert strings containing
said-formatted strings into HTML, which can then be styled to highlight which
parts will be substituted in messages.
Main thing that was missing was including the main CSS file in the template.
There are a few hacky bits here, like moving the whole of toolkit inside the
stylesheets directory.
Would arguably be cleaner using something that isn’t Flask Assets, but that’s
something for later.
