Traditionally a glossary comes at the end, but there are some terms we should be clear on before getting into the detail.
CMS - Content Management System. This is the platform that your website is built in, and the interface in which you do your editing. The look and some functions may differ depending on the age of the site, but most accessibility practices are applicable across the board.
WYSIWYG editor - ‘What you see is what you get’ editor. This refers the editor that the CMS uses in various blocks throughout the site, but most commonly in this guide, the content and accordion blocks. The WYSIWYG editor may also differ slightly depending on the age of the site as this may correspond to different CMS versions, but the functions references throughout this guide should be available throughout most versions.
See the image below for an example of the WYSIWYG editor in a content block.
Alt text - a shorthand term for ‘alternative text’, used throughout this guide in reference to accessibility in relation to images.
WCAG - Web Content Accessibility Guidelines. This is the set of guidelines currently at version 2.1, with criteria split into A, AA and AAA categories. Public sector websites in England are now expected to work towards the A and AA standards.
