WordPress is an increasingly popular framework for building and maintaining websites – from blogs through to brochureware sites for businesses. Statistics indicate that over 5 million sites worldwide are built upon WordPress Q. But is it possible to create accessible websites with WordPress? This presentation looks at the factors involved – things that can help, things that can hinder. And I want to talk about what I'm doing and hoping to do to improve the situation. I'm going to focus mainly on accessibility for site users but I will be covering the accessibility of the admin area towards the end of the presentation.

Notas do Editor
- Statistics indicate that over 5 million sites worldwide are built upon WordPressInformation from W3Techs shows that WordPress is used to power over 15% of the world’s one million largest websites and over 54% of all websites using a CMS.WordPress.org reports that 22 out of every 100 new active domains in the US are running WordPress, and the popularity of WordPress can be seen in Google Trends.
- Going to focus mainly on accessibility of the front end – ie accessibility of the website as rendered by WordPressBut I’m also going to cover the accessibility of the admin back end - the screens that people use to maintain their WordPress site.
- Choosing the right theme is the first part of the success or failure in our quest to produce an accessible websiteBlog orientated – betrays WordPress’ roots as a blogging tool.Out of date – don’t support newer features like custom menus or static home page, so can’t be used for brochureware sites
- Accessibility features can be baked in to the page templates at this stage or they can be left out.Most themes typically do not take accessibility into account – and in many casestheme developers probably only get it right by accident. Premium themes are no better in this regard – and can often be worse as they are often geared up for magazine or portfolio sites with lots of functionality which can be inaccessible – flash, ajax calls etc
- A brand new installation of WordPress will give you two default themes 'twentyten' and the newer 'twentyeleven' – a truly HTML5 theme. These themes are updated from time to time with new WordPress releases.Many people use the default themes as the basis for their site as there are a number of customisation options available (Demonstrate – use church site + flowers)Good NewsThe default WordPress themes are not too bad from an accessibility perspective and they're gradually getting better. Bad NewsUnfortunately there are still some issues that could be better. Examples:Fixed font size in content in twentytenSome colour contrast issues in twentytenKeyboard accessibility – menus still true in both (demonstrate)Search box label missing in twentyten but OK in twentelevenRead more links (demonstrate)Title attributes everywhere (demonstrate)
- Weaver II is a free, highly featured theme. A premium version is available that offers even more configuration.
- Could take a while but have started on design.
- The second opportunity to affect the level of accessibility of a website
- The functionality normally covers specific needs – eg SEO, Search, Backup, Maintenance, Social Media integration.More extensive ones (and typically more expensive) – eCommerce, Membership sites, etcPlugins can typically 'monkey around' with the HTML that is generated by the site's theme and is being delivered to the browser. So the plugin functionality can add to or subtract from the level of accessibility of a website.
- Demo - lightbox, carousel
- Demo – remove title attributes, chgfontsizechgFontSize only works successfully with themes where fixed fonts are not present. You also need to know a suitable container id to get it to work – beyond some people’s capability.
- Demo – dropdown menus, social bookmarks
- Content authors are the third strand in creating an accessible WordPress siteWordPress supports many features that authors can put in to ensure accessibility
- Visibility of focus has improved but still could be much better (demo)Nonsensical links - 5 pagesTab order can be confusingSome skip links would be usefulSome disabled users have learned how to use the backend as it was fairly constant over a period of time. They'd know that the 3rd link from the top was the Profile menu option etc. But with v 3.3 there were some UI changes that have forced people to relearn the screens.Blind users may disable the visual (WYSIWYG) editor as this is hard to use with a screen reader – demo. It helps if you know a bit of HTML.Sighted keyboard users can have a frustrating time because of the lack of visible focus in key areas. It is also v difficult or impossible to tab to key bits of functionality – eg adding images into posts or pages.
- A few WP developers have some basic knowledge of accessibility and a desire to incorporate it, but most don't.Within WP releases there is often a request for an accessibility review right at the end of the development process. This is really the opposite of what should happen as a11y needs to be built in from the start. There isn't much evidence that the suggestions that are received are implemented. WP developers feel they've be burned by 'accessibility experts' in the past and are suspicious as a result. My view is that it's a fundamental lack of understanding of how disabled users use the web – and significantly that different groups of disabled users have different needs.
- Demo – Accessible Admin Menus pluginBut then show tab order
