Header navigation margins option 2

[frankieroberto]

This is an alternative to #999 which achieves the same outcome (aligning the navigation items with the rest of the header) but in a different way, by removing the horizontal padding inside the links and having horizontal margin instead.

This means a slightly reduced target area for each link, but they should still be well above the minimums for usability and accessibly (so long as the link text is 4 or more characters).

It also means that the focused item is also aligned with the header.

This is similar to the approach of the GOV.UK Design System's new service navigation component, although that has a shorter focus style.

I think if you were going to use this approach, you’d still want some inline padding, say 2-4px, else it looks a bit odd, perhaps broken.

Yeah, I think I agree. The GOVUK one doesn't do that, but possibly the Transport font has a tiny bit more space in the characters compared to Frutiger?

I also kept the minimum margin between the items the same as the current padding-based spacing I think (nhsuk-spacing(6)) but perhaps it could be a little bit less.
