Visual users get the context from the proximity to
the h2 but we need to provide this for others.
I've tried using `aria-describedby` to link them
to the h2 but this ends up making the h2 text the
button's description in the accessibility tree. In
Voiceover this means you only get that information
as extra context, announced a while after the
label if the VO cursor stays on the button.
We want all the information in the accessible
label so chose this approach instead.
Paired with @aliuk2012 on the implementation and
with a view to making the component generic enough
to be used on digital marketplace apps as well.
These changes came from that session.
They include:
- removal of an unused `data-accept-cookies`
attribute
- removal of `govuk-!-padding-top-4` class and
moving of associated styles into component CSS
- swapping out the `aria-label` on the parent
element for an `aria-describedby` linked to the
h2 to have one thing labelling the banner region
- removal of unused CSS and any already provided
by the govuk-button class
- inclusion of @import's for styles attached to
govuk-body and govuk-button classes
Copies HTML and Sass from GOV.UK Pubishing
components cookie-banner with changes to content
and functionality to better suit Notify.
Changes are:
- adds a 'reject' button which the GOV.UK
code doesn't have
- adds Sass from the GOV.UK Frontend button
component which the GOV.UK version used so
is included here
- removed click tracking from cookie banner
