Hyperlink text incorporates the hyperlink destination/purpose (avoid raw URLs, e.g., https://www.canvaslms.com) and includes words and phrases to provide context for screen-readers (e.g., use “Canvas Guide: Hyperlink” rather than “Canvas Guide”). WebAim: Introduction to Links and Hypertext Optimize access to tools and assistive technologies by using links on your pages. Linking to your Home Page (or other areas where helpful information is located) is a fantastic way to assist with accessibility.
Audio materials (mp3, wav, etc.) are accompanied by a transcript, and videos/screencasts are closed-captioned. Canvas Guide: Create Caption Files Offer alternatives for auditory information. Audio can be powerful for all learners, but it can also isolate others. Be mindful for this when using audio.
Tables are used appropriately and are accessible. WebAim: Creating Accessible Tables Optimize access to tools and assistive technologies. Tables assist in making your content orderly and organized on your course page, and can assist screen readers in translating your information.
