When should an animation start on a webpage?

An animation should not start automatically when a page loads. This action goes against the user's choice to see the animation. A skip link must always be available for users who do not want to wait for a timer. CSS transitions should not be used on display properties.

The rule

An animation should not start automatically when a page loads.

This action goes against the user's choice to see the animation. A skip link must always be available for users who do not want to wait for a timer. CSS transitions should not be used on display properties.

An animation should not start when a page loads. This defeats the purpose of letting a user choose to see it. Users should decide when to engage with animations. A skip link is important. It gives users a way to stop or skip a timer or animation. This link must always be present and easy to find. Do not use CSS transitions for display changes. Instead, use opacity with a setTimeout pattern. This method provides better control and a smoother experience.

A developer creates a webpage with a pulsing animation. The animation starts as soon as the page loads. A user visits the page and finds the animation distracting. The user cannot easily stop the animation. This design choice frustrates the user and makes the page difficult to use.
