May 31, 2015 — With the REST API shortly due to be merged into WordPress core, this will be a talk/workshop about advanced theming techniques that allow theme developers to utilise it.

May 30, 2015 — Many WordPress websites use hand-crafted themes intended solely for one website. Creating a WordPress theme from scratch can seem daunting at first, but it is not as tricky as you may think. The talk is aimed at people who want to create a one-off theme for a single website (eg. a client project, personal blog), rather than building a theme for distribution. It will require previous knowledge of WordPress, HTML, CSS and basic familiarity with PHP.

May 30, 2015 — One of the recent WordPress accessibility initiatives has been the introduction of the ‘accessibility-ready’ tag for theme authors who wish to submit themes to the WordPress repository. The tag is used to indicate that a theme contains the best practices in web accessibility, and can form the basis of an accessible WordPress website. But uptake has been slow. This presentation looks at what you need to do to get your themes up to the ‘accessibility-ready’ standard – whether or not you intend to submit them to the repository.
