💡 Hint

Common Mistakes

Using invalid scale values like decimals or unsupported keywords.

Forgetting the hover: prefix to trigger animation on hover.

The class hover:scale-110 scales the image to 110% of its size on hover, creating a smooth zoom effect that draws user attention.

💡 Hint

Common Mistakes

Using made-up animation class names that Tailwind does not support.

Adding extra suffixes like '-forever' which are not part of Tailwind.

The correct Tailwind class for a continuous pulse animation is animate-pulse. Other options are not valid Tailwind classes and will not work.

💡 Hint

Common Mistakes

Using scale classes instead of background color classes for hover color change.

Forgetting to add transition duration class.

The class duration-500 sets the transition duration to 500ms, and hover:bg-red-700 changes the background color on hover smoothly.

hard

Fill all three blanks to create a card that fades in, moves up slightly, and grows on hover with smooth transitions.

<div class="bg-white p-6 rounded shadow-lg transition [1] [2] [3]">Card Content</div>

Drag options to blanks, or click blank then click option'

Danimate-fadeIn

Attempts:

💡 Hint

Common Mistakes

Using incorrect syntax for translate values.

Forgetting to add transition classes for smooth effect.

animate-fadeIn makes the card fade in on load, hover:translate-y-[-5px] moves it up slightly on hover, and hover:scale-105 grows it a bit. Together with duration-700 (optional), these create a smooth interactive effect.

   Tailwind requires the full animation class like animate-bounce, not just animate.

2. Step 2: Identify the missing part in the class

   The code uses bounce and animate separately, but it should be combined as animate-bounce.

3. Final Answer:

   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]

Common Mistakes:

• Using partial animation class names
• Thinking divs can't animate
• Believing inner text needs wrapping
