There are special needs users who access websites that a designer must take into consideration. This means designers must take care when using text, graphics, video, and audio. Without special care, the intended information and materials may be a complete waste to certain users.
Here are a few starting tips for dealing with various media:
Make text headlines prominent. Use text that is to the point. Use fonts that are easy to read.
Within image tags, there is an attribute called 'alt.' Using the 'alt' attribute helps visually impaired users gain a text alternative to graphics.
- Audio & Video
Accompany audio and video with a transcript. This will help people who suffer from hearing impairments.
The World Wide Web Consortium (2005) has much more information on accessibility.
