Decide what each movement is for
A button that changes color on hover, a menu that slides open, and a background that moves while someone scrolls all use motion differently. Before adding an effect, ask what it helps the visitor understand. A brief transition might make a change of state easier to notice. A looping decoration or dramatic page entrance may add little beyond visual style.
Make a short list of motion already on your site: carousels, animated illustrations, loading indicators, hover effects, scrolling effects, pop-ups, and page transitions. For each item, decide whether it conveys information, confirms an action, or is decorative. This small inventory gives you a manageable place to start and helps prevent new effects from being added without a purpose.
Treat reduced motion as a design preference
Visitors can set a reduced-motion preference in their device or browser settings. Websites can respond to it with the CSS media feature prefers-reduced-motion. When its value is reduce, the site can replace or limit effects that might be uncomfortable. The preference does not explain why a visitor chose it, so there is no need to guess. The useful response is to make the page work well with less movement.
A straightforward approach is to design important information and controls so they work without animation, then add motion where it improves the experience. You can use prefers-reduced-motion with the value no-preference for optional effects. For existing sites, add a reduce rule that turns off decorative animations and removes long transitions. Either way, check individual components rather than assuming one rule will produce a good result everywhere.
Keep feedback, but change how it appears
Reducing motion should not hide a menu, delay a message, or make a loading state impossible to recognize. If a panel normally slides into view, it can appear immediately instead. If a form submission normally triggers a bouncing confirmation, a visible message and a clear change of state can provide the same feedback. Hover and focus states can change color, border, underline, or contrast without relying on movement.
Pay particular attention to effects that move large parts of the screen, follow scrolling, repeat indefinitely, or start without a visitor’s action. These are strong candidates for removal or replacement in the reduced-motion version. A very brief change may be less disruptive than an elaborate animation, but it is still worth testing. The goal is not to make the page feel unfinished; it is to preserve meaning while avoiding unnecessary movement.
Cover motion outside ordinary CSS
A CSS rule will not automatically control every source of movement. JavaScript-driven transitions, animated images, videos, canvas effects, and third-party widgets may need separate handling. For scripts you maintain, check the reduced-motion media query before starting an optional animation. If a visitor changes the setting while the page is open, a script that listens for preference changes can update the experience rather than waiting for a reload.
For embedded media and widgets, inspect the controls and settings they provide. Avoid making essential instructions depend on an animation playing. If a moving demonstration carries information, provide a still image, text explanation, or other usable alternative where practical. When you cannot control an effect, consider whether that component is necessary or whether a quieter option could serve the same purpose.
Test the complete journey
Test with reduced motion enabled through your operating system or browser developer tools, then repeat with the usual setting. Navigate by keyboard as well as pointer. Open menus, submit forms, follow links, trigger error messages, and check any content that appears after a delay. Look for controls that become hard to find, content that flashes briefly, or elements left off-screen because an animation was disabled.
Add reduced-motion checks to your routine whenever you change a component with movement. For a small site, a simple checklist of pages and interactions may be enough. Ask two questions during each review: can visitors understand what changed, and can they complete the task without unwanted motion? Those questions keep the work focused on usability rather than on a particular visual effect.
