Fixed a cookie banner that would not close

For a few hours on launch day, the cookie banner on this site could not be dismissed. Clicking Allow or No thanks did nothing. It just sat there.

The cause was a small conflict in the styling. The banner was told to lay itself out in a particular way, and that instruction quietly outranked the separate instruction to hide it. So the code was doing exactly what it was asked — setting the banner to hidden — while the styling kept it on screen anyway. Nothing errored. It simply did not go away.

The fix was one line, making “hidden” mean hidden regardless of any other styling.

Worth saying plainly: this is on a site that sells checking whether things actually work. It is the sort of thing an automated check should have caught, and did not, because the checks look at whether pages load and whether the markup is valid — not at whether a button does what it says. That gap is now a known one.
