💼 Career

Knowing how to use Tailwind CSS for animations and accessibility is valuable for frontend web development roles focused on user experience.

1

Create the HTML structure with a button

Write the basic HTML5 structure with lang="en", charset="UTF-8", and a viewport meta tag. Inside the body, add a button element with the text Click me and an aria-label="Animated button".

Hint

Remember to add the aria-label attribute inside the button tag for accessibility.

2

Add Tailwind CSS link and basic button styles

Add the Tailwind CSS CDN link inside the <head>. Then add Tailwind classes to the button to make it have padding px-6 py-3, background color bg-blue-600, white text text-white, rounded corners rounded-md, and a smooth transition transition.

3

Add hover animations for color and scale

Add Tailwind classes to the button to change background color to bg-blue-700 on hover and scale the button to 105% with hover:scale-105. Also add duration-300 for smooth animation timing.

B. The button will change color to red instantly.

C. The button will stay static with no animation.

   The class animate is incomplete; it needs a specific animation like animate-bounce. -> Option C

   Full animation class needed = B [OK]

Hint: Use full animation class like animate-bounce [OK]
