The Webpage often contains clickable areas such as text links, images and buttons. In order to facilitate the user to recognize what is clickable, the text links should be underlined. Underlines are very important for users with low vision and are easier to see when the page is magnified.

Guidelines:

• The links should be underlined
• The colors used for links must be clearly distinguishable from the colors used for non-linked text
• Preferred color for links is blue

Good Example

Find out what new features have been added to the site

Bad Example:

Find out what new features have been added to the site

In this case for a person affected by color blindness, it is virtually impossible to tell which word is a link and which words are normal texts.

Validation Techniques:

• Check for the font color between the linked and non-linked text
• Verify for the links that are underlined
