B It allows you to write CSS styles inline without any classes.

C It helps you build UI components faster by using utility classes directly in your framework's components.

Correct Tailwind class usage in React JSX

Which option correctly applies Tailwind CSS classes to a button in React JSX?

Tailwind

function Button() {
  return (
    <button className="bg-blue-500 text-white p-2 rounded">
      Click me
    </button>
  );
}

A <button class="bg-blue-500 text-white p-2 rounded">Click me</button>

B <button className='bg-blue-500 text-white p-2 rounded'>Click me</button>

C <button className={bg-blue-500 text-white p-2 rounded}>Click me</button>

D <button className={"bg-blue-500 text-white p-2 rounded"}>Click me</button>

💡 Hint

Remember how JSX handles class names.

In React JSX, the attribute for CSS classes is 'className'. It must be assigned a string, so using curly braces with a string is correct.

Responsive design with Tailwind in a Vue component

What will be the visual result of this Vue template using Tailwind classes?

A The box background is green on small screens, red on medium screens, and blue on large screens.

B The box background is always blue regardless of screen size.

C The box background is green on all screen sizes because responsive classes don't work in Vue.

D The box background is red on small screens and green on medium and large screens.

💡 Hint

Think about how Tailwind applies responsive prefixes.

Tailwind applies styles based on screen size prefixes: 'md:' applies at medium screens and above, 'lg:' at large screens and above. So the background color changes as screen size grows.

Which Tailwind CSS utility or technique correctly applies a red text color only to direct

B Use 'section > p { @apply text-red-500; }' inside a Tailwind CSS file.

C Add 'text-red-500' class to all <p> elements globally.

D Use 'section p { color: red; }' in a separate CSS file without Tailwind.

💡 Hint

children of

Ensuring accessible focus styles with Tailwind in a React app

Which option best ensures visible focus outlines for keyboard users on buttons styled with Tailwind in React?

A Use 'focus:outline-2 focus:outline-blue-600' to show a clear outline on focus.

B Do not add any focus styles; browsers handle it automatically.

C Use 'focus:outline-none' to remove outlines and rely on color changes only.

D Use 'hover:outline-blue-600' to show outlines only on mouse hover.

💡 Hint

Think about keyboard navigation and visible focus indicators.

Removing focus outlines harms accessibility. Using Tailwind's focus utilities to add a visible outline helps keyboard users see which element is focused.
