Through his list I heard about Gian Wild’s recent tips through Russ Weakley’s excellent links for light reading. He finds lots of good articles every week on contemporary web development issues. HIGHLY RECOMMENDED
Gian Wild has some good advice on how to make your slider accessible
Gian and her company AccessibilityOz have been working on accessibility for many years.
The unbearable inaccessibility of slideshows | SitePoint | Gian Wild | Feb 2015
The key things are:
- Accessible controls (keyboard mouse, touch, colour contrast, semantic labels)

- Focus order makes sense
- Coded standards compliant

Have your really thought about the business case for putting a moving carousel on your site?
One of my pet peeves is slider that is set to automatically change on default. Why do business owners insist on this moving feast. If I am in a exploratory information seeking behaviour mode I may want to look at them. Otherwise they are a distraction. They almost always focus on what the business wants to market not what the customer wants to do.
