Layout
Use the built in layouts to enable correct reading order for assistive technology
Avoid using slide transitions (e.g. dissolve, fade)
Text
Avoid decorative fonts that are hard to read
Font size should be at least 18 point
Bold the text to call attention to important information
Avoid underlining text unless the text is a clickable hyperlink
Avoid italics unless necessary (e.g. book titles, scientific names)
Avoid using all caps
Color
Choose contrasting text and background colors (black/white, DDCC blue/white, purple/white)
Avoid patterned backgrounds when used with text
Use colors consistently throughout the presentation
Color alone should not indicate meaning
List of Items
Use the Bulleted List or Numbered List feature in the editing toolbar
Hyperlinks
Use descriptive links that tell the user where the link will take them
Embedded Media
Provide alt text for meaningful images or describe the image directly on the slide
Provide a linked transcript for audio-only files
Choose captioned videos or edit captions on videos that you create
Tables
Use tables to display data
Avoid using tables for design or layout - Format the slide into columns instead
Use the “Insert Table” feature rather than inserting an image of a table
Choose contrasting text and cell colors (e.g. white text, DDCC blue cell)
Avoid blank, merged, or split cells
Mark the table column/row row headers by running Grackle
