I have finally got around to updating my own website from static html to a custom built WordPress template with a blog. The process was pretty straightforward as I already had the site in compliant XHTML 1.0 Strict so I just had to create some styling for the comments section and split the code into the relevant WordPress template pages. The biggest delay was sorting out all the content to use on the website, grabbing screenshots and reformatting them. Something I usually have to pressure my clients for.
One thing I learned from the process is that new aria-required attribute that WordPress adds to required input fields, makes the page fail the W3C HTML validator. It is however, actually good for accessibility as modern screen readers inform the user that this is a required field, giving blind users a better experience than a bold asterisk.
