💡 Why This Matters

🌍 Real World

Responsive typography is essential for websites to look good and be readable on phones, tablets, and desktops. This skill helps create user-friendly websites.

💼 Career

Web developers often use Tailwind CSS to quickly build responsive designs. Knowing how to scale typography responsively is a common task in front-end development.

1

Create the basic HTML structure

Create a basic HTML5 skeleton with lang="en", charset="UTF-8", and a viewport meta tag. Inside the <body>, add a <main> element containing an <h1> with the text "Welcome to My Blog" and a <p> with the text "This is a sample paragraph to demonstrate responsive typography."

    Welcome to My Blog
    This is a sample paragraph to demonstrate responsive typography.

Hint

Start with a simple HTML page. Use <main> for the main content. Add the heading and paragraph inside it.

2

Add Tailwind CSS link and base typography classes

Add the Tailwind CSS CDN link inside the <head> section. Then, add Tailwind classes class="text-base p-4" to the <main> element to set base font size and padding.

Hint

Use the official Tailwind CDN link: https://cdn.tailwindcss.com. Add text-base and p-4 classes to <main>.

3

Make the heading text scale responsively

Add Tailwind classes to the <h1> element so that the font size is text-2xl on small screens, text-4xl on medium screens, and text-6xl on large screens.

Hint

Use Tailwind's responsive prefixes: md: for medium screens and lg: for large screens.

4

Make the paragraph text scale responsively

Add Tailwind classes to the <p> element so that the font size is text-sm on small screens, text-base on medium screens, and text-lg on large screens.

Hint

Use the same responsive prefixes for the paragraph text sizes as you did for the heading.

Practice

1. What does the Tailwind class text-lg md:text-xl do in terms of font size?

easy

A. Sets the font size to large on small screens and extra large on medium and bigger screens.

B. Sets the font size to extra large on all screen sizes.

C. Sets the font size to large only on medium screens.

D. Sets the font size to extra large only on small screens.

Solution

1. Step 1: Understand Tailwind responsive prefixes

   The prefix md: applies styles starting from medium screen sizes (768px and up).

2. Step 2: Interpret the class text-lg md:text-xl

   It sets font size to large by default, then changes to extra large on medium and larger screens.

3. Final Answer:

   Sets the font size to large on small screens and extra large on medium and bigger screens. -> Option A

4. Quick Check:

   Responsive prefix changes font size at medium breakpoint [OK]

Hint: Look for prefixes like md: to spot screen size changes [OK]

Common Mistakes:

• Thinking md: applies to small screens
• Assuming no change in font size
• Confusing default and prefixed classes

2. Which of the following is the correct Tailwind syntax to make text size small on mobile and medium on large screens?

easy

A. text-md lg:text-sm

B. text-sm lg:text-md

C. text-sm lg:text-lg

D. text-lg md:text-sm

Solution

1. Step 1: Identify correct font size classes

   Tailwind uses text-sm for small, text-md is not a valid class, text-lg is medium-large.

2. Step 2: Check responsive prefix usage

   lg: applies styles at large screens (1024px+). So text-sm lg:text-lg means small text on mobile, larger text on large screens.

3. Final Answer:

   text-sm lg:text-lg -> Option C

4. Quick Check:

   Use valid classes and correct prefixes [OK]

Hint: Remember text-md is invalid; use text-sm, text-base, text-lg [OK]

Common Mistakes:

• Using invalid class text-md
• Reversing screen size prefixes
• Mixing up font size names

3. What font size will the text have on a 1200px wide screen with this class: text-base sm:text-lg md:text-xl lg:text-2xl?

medium

A. text-base

B. text-xl

C. text-lg

D. text-2xl

Solution

1. Step 1: Identify screen size breakpoints

   1200px width is larger than lg breakpoint (1024px), so lg: classes apply.

2. Step 2: Determine which font size applies

   Since lg:text-2xl applies at 1024px+, the font size will be 2xl on 1200px screen.

3. Final Answer:

   text-2xl -> Option D

4. Quick Check:

   Largest breakpoint prefix applies at wide screens [OK]

Hint: Pick the largest breakpoint prefix less than screen width [OK]

Common Mistakes:

• Choosing smaller breakpoint sizes
• Ignoring lg: prefix effect
• Confusing breakpoint order

4. You wrote text-base md:text-lg sm:text-xl but the font size is not increasing on medium screens. What is the problem?

medium

A. Tailwind does not support multiple responsive prefixes on one element

B. The order of responsive prefixes is incorrect; sm: should come before md:

C. You must use lg: instead of md: for medium screens

D. The base font size must be larger than responsive sizes

Solution

1. Step 1: Understand responsive prefix order

   Tailwind applies styles in order of screen size: base, sm, md, lg, xl.

2. Step 2: Check class order impact

   Classes are applied left to right, so md:text-lg is overridden by sm:text-xl because sm: is smaller breakpoint but comes later.

3. Final Answer:

   The order of responsive prefixes is incorrect; sm: should come before md: -> Option B

4. Quick Check:

   Order responsive classes from smallest to largest breakpoint [OK]

Hint: Write responsive classes from smallest to largest breakpoint [OK]

Common Mistakes:

• Placing larger breakpoint classes before smaller ones
• Assuming Tailwind ignores class order
• Confusing breakpoint sizes

5. You want text to be text-sm on mobile, text-base on tablets (640px+), and text-lg on desktops (1024px+). Which Tailwind class combination achieves this?

hard

A. text-sm md:text-base lg:text-lg

B. text-sm sm:text-lg md:text-base

C. text-sm sm:text-base md:text-lg

D. text-base sm:text-sm lg:text-lg

Solution

1. Step 1: Match breakpoints to screen sizes

   Mobile is default (no prefix), tablets start at sm (640px), desktops at lg (1024px). For 1024px+, lg: is correct for desktops.

2. Step 2: Check class correctness

   text-sm default for mobile, md:text-base applies at 768px+, and lg:text-lg applies at 1024px+. This combination ensures text-base on tablets (md breakpoint) and text-lg on desktops (lg breakpoint).

3. Final Answer:

   text-sm md:text-base lg:text-lg -> Option A

4. Quick Check:

   Use default, then md:, then lg: for ascending screen sizes [OK]

Hint: Use default, then md:, then lg: for ascending screen sizes [OK]

Common Mistakes:

• Mixing breakpoint order
• Using lg: instead of md: for tablets
• Setting smaller sizes on larger screens
