I would like to know how to add a block at the very top of every page in my website.
It would be just a 'bar' with the purpose of displaying important information periodically, like - for example - when I am on holiday and unable to process orders. Or perhaps when there is a promotion running.
It's position would be above the site's header section - exactly where the cookie restriction banner gets placed by default.
Ideally I'd like it to be a block so that it's easily enabled/disabled and edited.
