Render Quiz - 3 Questions

After applying step 1, how does the heading appear?

A Large, bold text with space below

B Small, normal weight text with no margin

C Italic text with tight spacing

D Invisible text

Common Confusions - 3 Topics

Why does my heading look too small even with text-4xl?

Tailwind's text-4xl sets a specific font size, but if the parent container or browser zoom changes, it can affect appearance. Also, missing font-bold can make it look less prominent (see step 1).

💡 Always combine size and weight classes for clear headings.

Why is my paragraph text cramped vertically?

Without line-height control like leading-relaxed (step 2), lines can be too close, making reading harder.

💡 Use line-height classes to add comfortable spacing between lines.

Why does italic text sometimes look out of place?

Italic changes style but not size or spacing. If margin or font size is not adjusted (step 3), it may visually clash with other text.

💡 Combine italic with size and margin classes for balanced look.

Concept Snapshot

Typography control adjusts font size, weight, spacing, and style. Tailwind classes like text-4xl, font-bold, leading-relaxed control these visually. Good typography improves readability and user experience. Spacing (margin, line-height) separates text blocks clearly. Style (italic, bold) adds emphasis and variety. Without control, text can look cramped, unclear, or unbalanced.

1. Step 1: Check Tailwind letter spacing classes

   Tailwind uses tracking- prefix for letter spacing, e.g., tracking-wide, not letter-spacing-2.

2. Step 2: Identify invalid class

   letter-spacing-2 is not a valid Tailwind class, so it won't apply spacing.

3. Final Answer:

   The class letter-spacing-2 is invalid in Tailwind. -> Option B

4. Quick Check:

   Letter spacing uses tracking- prefix = A [OK]

Hint: Use 'tracking-' prefix for letter spacing in Tailwind [OK]
