Assess your skills with Tailwind’s utility-first approach to animations and transitions. Explore core concepts like duration, timing functions, and applying custom motion effects using Tailwind classes.
Which Tailwind class should you use to apply a continuous spinning animation to an element, such as an icon or button?
Explanation: The animate-spin class applies a continuous spinning animation to an element using Tailwind. The options animation-fast, transit-spin, and spin-animate are not valid Tailwind classes and will not generate any animation. While they sound plausible, only animate-spin follows Tailwind’s naming structure and is officially supported for this effect.
If you want a button to smoothly change background color over 700 milliseconds when hovered, which Tailwind class would you use to set this duration?
Explanation: The duration-700 class sets the transition duration to 700 milliseconds, allowing for a smooth color change. delay-700 adds a delay before the transition starts, not the speed itself. timing-700 and speed-700 are not recognized Tailwind classes, making them ineffective for controlling transition timing.
To limit the transition on a card component to only affect opacity changes, which Tailwind class should you apply?
Explanation: The transition-opacity class ensures that only opacity changes will be animated during transitions. transition-shadow only applies to shadow changes, and only-opacity or change-opacity are not valid Tailwind classes. Using transition-opacity provides specific control over which properties will animate.
Which Tailwind class applies an ease-in timing function, causing an element to start slow and finish fast in its transition?
Explanation: The ease-in class defines a transition to start slowly and accelerate towards the end, fitting the description given. transition-easy and slow-fast are not Tailwind utility classes, while ease-linear ensures a constant speed without acceleration or deceleration.
Which of the following class combinations allows an icon to both spin continuously and smoothly fade in when it appears?
Explanation: The animate-spin class makes the icon spin, while transition-opacity enables smooth changes in opacity (such as fading in). The combinations spin-fadein, animate-smooth, animate-fade, transition-spin, transition-fadein, and spin-anim are not Tailwind classes, so they wouldn’t create the intended effect. Only animate-spin transition-opacity consists of valid, functional utilities.
