C. "colors": { 'brand-blue': #1DA1F2 }

D. "colors": { brand-blue: "#1DA1F2" }

   Keys must be strings in quotes, and color values must be strings in quotes.

2. Step 2: Identify the correct option

   "colors": { 'brand-blue': '#1DA1F2' } uses quotes correctly around both key and value, making it valid.

3. Final Answer:

• Using wrong quote types inconsistently

3. Given this Tailwind config snippet:

{
  theme: {
    extend: {
      colors: {
        'brand-green': '#10B981'
      }
    }

medium

A. Using bg-brand-red instead of text-brand-red.

Solution

1. Step 1: Understand Tailwind config changes

   Changes to Tailwind config require restarting the dev server to apply.

2. Step 2: Identify the common mistake

   Not restarting means new colors won't load, so bg-brand-red won't work.

3. Final Answer:

   Forgetting to restart the development server after config change. -> Option D

4. Quick Check:

   Restart server after config edits = Forgetting to restart the development server after config change. [OK]

Hint: Always restart dev server after Tailwind config changes [OK]

• Missing # in hex code (usually caught earlier)

5. You want to create a consistent color system with Tailwind for a team. Which approach best helps keep colors consistent and easy to update?

hard

A. Define all custom colors in Tailwind config and use their names in classes.

B. Use inline styles with hex codes everywhere in HTML.

C. Add colors directly in CSS files without Tailwind classes.

D. Let each developer pick their own colors for components.

Solution

1. Step 1: Consider team consistency needs

   Using a shared config with named colors ensures everyone uses the same colors.

2. Step 2: Compare options

   Inline styles and separate CSS files cause inconsistency and harder updates; letting developers pick freely causes mismatch.

3. Final Answer:

   Define all custom colors in Tailwind config and use their names in classes. -> Option A

4. Quick Check:

   Central config for colors = consistency and easy updates [OK]

Hint: Centralize colors in config for team consistency [OK]
