Decide on how the mixins should change for new focus styles

[NickColley]

What

Make a decision on how the mixins should change with the new focus states in mind.

Why

Since we've changed the focus styles the old mixins are not necessarily fit for purpose and need to be removed or updated.

Until now we have been adjusting the temporary mixins as needed, but now we have all the new focus states merged we can look at them all together.

Mark Green is also going to be writing guidance around these mixins so we should include him wherever possible in this process.

We're updating the focus style as part of making the Design System meet WCAG 2.1 – specifically with regard to WCAG 2.1 1.4.11 Non-Text Contrast (#1137).

Who needs to know about this

• Developers
• Mark Green
• Dave House
• Amy Hupe (optional)

Done when

• Put together a proposal for what the new mixins should look like
• Run a meeting to run through proposal and get feedback from the team
