It can be fun to play with CSS transitions, but it's a terrible idea to use them in practice in probably about 95% of cases. Animation is basically visual spam.

It can be fun to play with CSS transitions, but it's a terrible idea to use them in practice in probably about 95% of cases. Animation is basically visual spam. I recently saw one footer bar that would appear by dropping down from the top of the page after the user started scrolling. Then when the user clicked the X, the bar would slowly float up, then fall back down (off the screen) quickly. The situation has become completely absurd.
