Link text & button labels

As you can tell by the number of Success Criterion (SC) associated with this topic, there is a lot to get wrong with the humble link and button. 

When creating links and buttons, we need to consider:

• Link text conveys purpose
• Uniqueness of button label and link text
• Contrast legibility
• Indicating state change that does not rely on colour alone
• Hit area size
• Focus indicator
• Duplication of links
• Button and text is scalable to 200%
