Bag of Spanners
In the UK we say that something is a "bag of spanners" when it seems to work, but when you look inside it turns out to be badly implemented.
Implementing accessible code can sometimes feel like a bag of spanners – something thrown together in ways that will probably give you (or someone using your product) trouble.
It doesn't have to be like this though.
With an understanding of how accessibility mechanics work in the browser, knowledge of how to provide or polyfill accessibility semantics, and a little bit of effort, you can turn your bag of spanners into a useful set of tools.
