I’ve also souped up the metadata that gets output in the page’s code, so that I’m now outputting a meta description tag – this outputs whatever I’ve typed into the page’s Description field in MODx.

I’ve also started using MODx built in meta keywords system, so some pages now have some keywords set.

A little while age I also added a Creative Commons license to the page footer but forget to mention it on the blog. This means that the site’s content is now actually marked as copright of Codeistry now – which it wasn’t before. As I’ve chosen a Creative Commons Attribution Non-Commercial Share Alike license, this also means that anyone can re-use, re-mix, translate or re-purpose any of the stuff on here for whatever they want, provided it’s non-commercial and they credit the original source.

Anyway, here’s the old footer:

and here’s the new one:

The changes are subtle but move the site from mostly failing to almost completely passing the contrast and luminosity tests from JucyStudio.

It might seem obvious but going through this process brought home to me how much the perceived contrast of text depends on the background colour behind it. Text that looks fine on the normal page background might have insufficient contrast when used in a footer, link or menu – where the background colours are different.

The changes included changing the body text to use the old heading colour, using a slightly darker colour for headings and links, and a slightly lighter shade for the page footers, to increase the contrast with the footer text.

I actually think that this has helped the design too – not only for accessibility but it also feels stronger, with more impact and weight. I may even revisit this in the future and punch it up a bit more.
