Web accessibility is all about creating an inclusive online environment for all users, including those with disabilities. One important aspect of web accessibility is the use of CSS selectors that accommodate users with motion sensitivity, such as those with vestibular disorders. One way to do this is by using the “prefers-reduced-motion” media query in CSS selectors.

The “prefers-reduced-motion” media query is a CSS selector that checks whether a user has indicated a preference for reduced motion in their operating system or browser settings. If a user has indicated a preference for reduced motion, the media query can be used to apply specific styles that reduce or eliminate motion in the website’s animations and transitions.

Here’s an example of using the “prefers-reduced-motion” media query in CSS selectors:

/* Normal animation styles */
.my-element {
animation: my-animation 1s ease-in-out;
}

/* Reduced motion styles */
@media (prefers-reduced-motion: reduce) {
.my-element {
animation: none;
transition: none;
}
}

In the above example, we use the “my-element” class to apply a normal animation style using the “my-animation” animation. However, we also use the “prefers-reduced-motion” media query to apply reduced motion styles to the “my-element” class when a user has indicated a preference for reduced motion.

The reduced motion styles in the media query include setting the animation and transition properties to “none”, effectively eliminating motion from the element.

By using the “prefers-reduced-motion” media query in CSS selectors, web designers and developers can create more accessible websites that are sensitive to users with motion sensitivity. This helps to ensure that all users can access and interact with the website without experiencing discomfort or other adverse effects.
