Improving Accessibility of CMS-based Websites Using Automated Methods.

New methods of identifying and fixing accessibility issues on websites are presented in this article. The websites taken into consideration by the research are created with content management systems (like WordPress or Joomla!). Our main goal was to develop different methods to improve accessibility that may be used by various user groups (website creators, operators, content editors). Some of our methods are easy to use, some need more proficiency. The three methods we have developed (CSS/SCSS class override, MVC-based extension override, HTML output override) are described in detail. The use of an already existing method (Data entry checking) is also introduced, as well as some development options of this method. Each method is introduced in general, furthermore an example of their usage is also presented. Using the proposed methods, websites can fulfil the recommendations of the Web Content Accessibility Guidelines (WCAG) in order to make the content of the websites more accessible.
