Visual: A woman puts on glasses to read a website on her laptop. The woman is squinting at the website with small text and an unusual font.

Audio: Properly coded websites and applications allow the text to be customized. For example, to change its size, spacing, font, and colors without loss of functions or clarity.

Visual: The woman uses the web browsers settings to adjust the text size and style. It appears more legible and the woman is relieved.
