1. Q1(i): HTML Element vs Tag
• An HTML tag is a keyword surrounded by
angle brackets like <p>.
• An HTML element includes the tag, its
content, and closing tag, e.g., <p>Text</p>.

2. Q1(ii): Hyperlink (New Tab)
• <a href="https://example.com"
target="_blank">Visit Example</a>

3. Q1(iii): Purpose of alt Attribute
• The alt attribute provides alternative text for
images. It helps in SEO and is displayed if the
image fails to load.

4. Q1(iv): Semantic HTML Tags
• <article>: Defines independent, self-contained
content.
• <section>: Groups related content together.

5. Q1(v): Purpose of <div> and
<span>
• <div> is a block-level container used for layout.
• <span> is an inline container used for text
styling.

6. Q1(vi): Function of class Attribute
• The class attribute is used to apply CSS styles
to HTML elements.
• Example: .red { color: red; }

7. Q1(vii): Ordered List HTML
• <ol>
• <li>Item One</li>
• <li>Item Two</li>
• <li>Item Three</li>
• </ol>

8. Q1(viii): Padding vs Margin in CSS
• Padding is space between content and border.
• Margin is space outside the border, separating
elements.

9. Q1(ix): Code Interpretation
• The element has both .container and #box
styles.
• #box overrides class: text becomes red,
background lightgray.

10. Q1(x): Internal vs Inline CSS
• Internal CSS is defined in the <style> tag in the
head.
• Inline CSS is written directly in the HTML
element using the style attribute.

<section>, <footer>.

• <section>
• <div class='left'>Left Content</div>
• <div class='right'>Right Content</div>
• </section>

12. Q2: CSS Explanation
• Use Flexbox or Grid for layout. Example CSS:
• .container { display: flex; }
• .left, .right { width: 50%; padding: 10px; }
• Style header and footer with background and
text alignment.
• Explain each section's purpose: header for
branding, nav for links, section for main
content.

13. Q3: CSS Box Model
• The CSS box model includes:
• 1. Content – actual text or image
• 2. Padding – space around content
• 3. Border – line around padding
• 4. Margin – space outside border

• div {
• margin: 20px;
• border: 2px solid black;
