1. What is the correct HTML tag to link an external CSS file to an HTML document?
easy
A. <script>
B. <style>
C. <link>
D. <css>

Solution

  1. Step 1: Identify the tag used for linking external resources

    The <link> tag is used in HTML to connect external files like CSS.

  2. Step 2: Confirm the tag's purpose for CSS

    <style> is for internal CSS, <script> is for JavaScript, and <css> is not a valid tag.

  3. Final Answer:

    <link> -> Option C

  4. Quick Check:

    Link CSS with <link> tag [OK]
Hint: Use <link> tag inside <head> to connect CSS [OK]
Common Mistakes:
  • Using <style> tag for external CSS
  • Using <script> tag instead of <link>
  • Trying to use a non-existent <css> tag
2. Which of the following is the correct syntax to link a CSS file named "styles.css" in your HTML document?
easy
A.
B.
C.
D.

Solution

  1. Step 1: Check the correct attributes for linking CSS

    The <link> tag needs rel="stylesheet" and href="filename.css" to link CSS properly.

  2. Step 2: Eliminate incorrect attribute usage

    rel="script" is wrong, <style> does not use src, and <script> is for JavaScript files.

  3. Final Answer:

    <link rel="stylesheet" href="styles.css"> -> Option A

  4. Quick Check:

    Use rel="stylesheet" and href for CSS link [OK]
Hint: Use rel="stylesheet" and href="file.css" in <link> [OK]
Common Mistakes:
  • Swapping rel and href attribute values
  • Using <style> tag with src attribute
  • Using <script> tag for CSS files
3. Given this HTML snippet, what will be the color of the paragraph text?
<head>
  <link rel="stylesheet" href="styles.css">
</head>
<body>
  <p>Hello World!</p>
</body>

And the CSS file styles.css contains:
p { color: blue; }
medium
A. Red
B. Blue
C. Green
D. Black (default)

Solution

  1. Step 1: Understand the CSS selector and property

    The CSS targets all <p> elements and sets their color to blue.

  2. Step 2: Confirm the CSS file is linked correctly

    The HTML uses <link rel="stylesheet" href="styles.css">, so styles.css applies to the page.

  3. Final Answer:

    Blue -> Option B

  4. Quick Check:

    Linked CSS sets <p> color to blue [OK]
Hint: Linked CSS styles apply to matching HTML elements [OK]
Common Mistakes:
  • Assuming default black color without checking CSS
  • Confusing CSS file name or path
  • Ignoring the <link> tag in <head>
4. What is wrong with this HTML code if the CSS file "main.css" is not applying styles?
<head>
  <link rel="stylesheet" href="main.css">
</head>
<body>
  <h1>Welcome</h1>
</body>

Assuming the file "main.css" exists in the same folder.
medium
A. The <link> tag is correctly placed and written.
B. The <link> tag should be inside the <body> tag.
C. The href attribute value is incorrect.
D. The <link> tag is missing the 'rel' attribute.

Solution

  1. Step 1: Check the <link> tag attributes

    The <link> tag has rel="stylesheet" and href="main.css", which is correct.

  2. Step 2: Verify placement of the <link> tag

    The <link> tag is correctly placed inside the <head> section, which is standard practice.

  3. Final Answer:

    The <link> tag is correctly placed and written. -> Option A

  4. Quick Check:

    Correct <link> tag with rel and href in <head> [OK]
Hint: Place <link> in <head> with rel and correct href [OK]
Common Mistakes:
  • Putting <link> inside <body> instead of <head>
  • Forgetting rel="stylesheet" attribute
  • Incorrect file path in href
5. You want to link two CSS files, "base.css" and "theme.css", to your HTML page. "theme.css" should override some styles in "base.css". Which is the correct way to link them?
hard
A.
B.
C.
D.

Solution

  1. Step 1: Understand CSS loading order

    CSS files loaded later override earlier ones if selectors match.

  2. Step 2: Place base.css first, then theme.css

    Link base.css first, then theme.css so theme.css can override base styles.

  3. Step 3: Check options for correct syntax and order

    <link rel="stylesheet" href="base.css"> <link rel="stylesheet" href="theme.css"> links base.css first, then theme.css correctly. <link rel="stylesheet" href="theme.css"> <link rel="stylesheet" href="base.css"> reverses order. <style>@import url('theme.css'); @import url('base.css');</style> uses @import inside <style> tag but loads theme.css first then base.css, so base overrides theme incorrectly. <link rel="stylesheet" href="base.css" theme="theme.css"> is invalid syntax.

  4. Final Answer:

    <link rel="stylesheet" href="base.css"> <link rel="stylesheet" href="theme.css"> -> Option D

  5. Quick Check:

    Load base.css before theme.css for overrides [OK]
Hint: Link base.css first, then theme.css to override [OK]
Common Mistakes:
  • Reversing the order of CSS files
  • Using invalid attributes in <link>
  • Using @import inside <style> instead of <link>
