easy

A. border-2

B. border

C. border-solid-1

   border-2 adds a 2px border, border-solid-1 and border-line are not valid Tailwind classes.

3. Final Answer:

   border -> Option B

4. Quick Check:

   1px solid border = border [OK]

Hint: Use 'border' for default 1px solid border [OK]

Common Mistakes:

3. What will be the visible effect of this Tailwind code?

<div class="border border-red-500 p-4">Hello</div>

medium

A. A red border around the text with padding inside.

B. No border, only red text color.

C. A thick red background behind the text.

D. Text with no padding or border.

2. Step 2: Understand the visual output

   The text "Hello" will have space around it (padding) and a red border around the entire box.

3. Final Answer:

   A red border around the text with padding inside. -> Option A

4. Quick Check:

   border + red color + padding = A [OK]

Hint: border + color class = colored border; p-4 adds padding [OK]

Common Mistakes:

• Thinking border-red-500 colors text

• Assuming background color changes

4. Identify the error in this Tailwind code that prevents the border from showing:

<div class="border-red-500 p-2">Content</div>

   border-red-500 sets border color but does not add border width or style alone.

2. Step 2: Identify missing class

   The base border class is needed to add a 1px solid border; without it, color alone won't show a border.

3. Final Answer:

   Missing the base border class to define border width. -> Option A

4. Quick Check:

   border color needs base border class = A [OK]

Hint: Always include 'border' with color classes to show border [OK]

Common Mistakes:

• Assuming color class adds border width
• Confusing padding with border
• Ignoring missing base border class

5. You want to create two side-by-side boxes with a clear boundary between them using Tailwind. Which combination of classes best achieves this?

hard

A. flex border border-gray-400 p-4 gap-4 on a container with two child divs without borders

B. grid grid-cols-2 border border-gray-400 p-4 on each child div separately

C. block border border-gray-400 p-4 on container only

D. flex gap-4 on container and border border-gray-400 p-4 on each child div

Solution

1. Step 1: Understand layout and boundaries

   To place boxes side-by-side, use flex or grid on the container. To show boundaries between boxes, each box needs its own border.

2. Step 2: Evaluate options

   flex gap-4 on container and border border-gray-400 p-4 on each child div uses flex gap-4 on container for spacing and adds border border-gray-400 p-4 on each child for clear boundaries. This creates distinct boxes with space between them.

3. Final Answer:

   flex gap-4 on container and border on each child div -> Option D

4. Quick Check:

   Separate borders on children + flex layout = C [OK]

Hint: Add borders on children, use flex with gap on container [OK]

Common Mistakes:

• Adding border only on container hides boundaries between children
• Using grid but missing borders on children
• Not adding gap between boxes
