Canvas HTML Editor Overview
Canvas content is built with the Rich Content Editor (RCE), allowing you to type text, format, insert images, and more. The RCE also offers HTML view to enhance content in ways the what-you-see-is-what-you-get (WYSIWYG) view cannot. To add HTML to a Canvas course, open the RCE anywhere in your course, and click the HTML toggle button. The HTML editor button is represented with a less than-slash-greater than symbol in the option along the bottom toolbar.

HTML Considerations
- Not all HTML is accepted by Canvas.
- All customizations must meet WCAG Level A and Level AA compliance.
- HTML code must be written perfectly for it to work.
- Enter replacement text exactly where placeholders appear in the copied code.
- Avoid extra spacing or duplicating punctuation that is not represented in the code provided.
- Backspace and delete can mess up your HTML in the RCE.
- You can copy HTML anywhere in your course for a consistent appearance.
- Always confirm the results of your work before publishing.
