When adding text in Canvas, it is good practice to use 'text styles'. Using Styles automatically formats the page for use by screen readers and other accessibility software. Using styles to format your page is easy...

Styles are accessible in the RCE toolbar. You can select the style before typing, or you can type first then highlight the text and select the desired style from the list.

Use the 'Paragraph' style to format all main text content.
Use 'Header 2' to format any titles or headings
Use 'Header 3' to format any subheadings

For example:

This is a title formatted with Header 2

This is formatted with paragraph. This is formatted with paragraph. This is formatted with paragraph. This is formatted with paragraph. This is formatted with paragraph.

This is formatted with Header 3.

This is formatted with paragraph. This is formatted with paragraph. This is formatted with paragraph. This is formatted with paragraph. This is formatted with paragraph. This is formatted with paragraph. This is formatted with paragraph. This is formatted with paragraph. This is formatted with paragraph. This is formatted with paragraph. This is formatted with paragraph. This is formatted with paragraph. This is formatted with paragraph. This is formatted with paragraph. This is formatted with paragraph.

Lists

You should also use lists appropriately. For example a numbered list should be used for sequential processes:

Do this
Do that
Then do this to finish

Unordered Lists should be used for bullet points

Point 1
Point 2
Point 3 etc

Tables

Use tables for displaying tabular data, not for layout. Keep table structures simple. Column and row headers should be used where appropriate to distinguish the titles for each column/row from the content. A caption should be used to describe the content of the table.

To create Table headers:

Highlight your headers
Select cell properties
Select 'header' from the cell type menu
Next, use the Scope option to designate if the header applies to a row or a column.
