Solved Short Questions (Simple & Easy Language)

1. What is the purpose of the `<head>` tag in HTML?

The <head> tag contains important information about the web page that is not visible to users. It includes:

The title of the page (<title>)
Links to CSS files (<link>)
Meta information (<meta>)
JavaScript files (<script>)

2. Explain the difference between an ordered list and an unordered list in HTML.

Ordered List (<ol>): It shows items in a numbered format (1, 2, 3…).
Unordered List (<ul>): It shows items with bullet points (●, ■, ○).

Example:

<ol>
  <li>First Item</li>
  <li>Second Item</li>
</ol>

<ul>
  <li>First Item</li>
  <li>Second Item</li>
</ul>

3. How do you add a comment in CSS?

In CSS, we use /* */ for comments.
Example:

/* This is a comment */
p {
  color: blue; /* This line changes text color to blue */
}

Comments are ignored by the browser and are used to explain code.

4. What are the different ways to apply CSS to an HTML document?

There are three ways to apply CSS:

Inline CSS – Written inside the HTML tag using the style attribute. <p style="color: red;">Hello</p>
Internal CSS – Written inside the <style> tag in the <head> section. <style> p { color: blue; } </style>
External CSS – Written in a separate .css file and linked using <link>. <link rel="stylesheet" href="style.css">

5. How can you include JavaScript in an HTML file?

We can include JavaScript in two ways:

Inline JavaScript: Inside the <script> tag in the HTML file. <script> alert("Hello World!"); </script>
External JavaScript: Linking a separate JavaScript file (.js). <script src="script.js"></script>

6. Describe the syntax for creating a hyperlink in HTML.

A hyperlink is created using the <a> tag with the href attribute.
Example:

<a href="https://www.google.com">Visit Google</a>

This will create a clickable link that opens Google.

7. What is the function of the `<div>` tag in HTML?

The <div> tag is used to group other HTML elements together. It helps in styling and layout design.

Example:

<div style="background-color: lightgray; padding: 10px;">
  <p>This is inside a div.</p>
</div>

It is like a container for other elements.

8. How do you link an external CSS file to an HTML document?

We use the <link> tag inside the <head> section.

Example:

<link rel="stylesheet" href="style.css">

This connects an external style.css file to the HTML page.

9. What is the use of the `<table>` tag in HTML?

The <table> tag is used to create tables to display data in rows and columns.

Example:

<table border="1">
  <tr>
    <th>Name</th>
    <th>Age</th>
  </tr>
  <tr>
    <td>Ali</td>
    <td>15</td>
  </tr>
</table>

This will create a simple table with a border.

10. Explain the box model in CSS.

The CSS box model explains how elements are displayed on a webpage. It includes:

Content – The main text or image inside the box.
Padding – Space inside the box, around the content.
Border – The outer edge of the box.
Margin – Space outside the box, separating it from other elements.

Example:

div {
  width: 200px;
  padding: 10px;
  border: 5px solid black;
  margin: 20px;
}

This defines a box with content, padding, border, and margin.

💡 Tip for Students: Keep practicing with small HTML and CSS examples to understand better. 🚀

Solved Long Questions (Simple & Easy for Class 9)

1. Discuss the fundamental differences between HTML, CSS, and JavaScript in the context of web development.

In web development, HTML, CSS, and JavaScript work together to create a complete website. Here’s how they differ:

Feature	HTML	CSS	JavaScript
Purpose	Structure of a webpage	Styling and design	Makes the webpage interactive
What it does	Defines headings, paragraphs, images, tables, etc.	Changes colors, fonts, layout, and animations	Adds buttons, forms, and real-time interactions
Example	`<h1>Heading</h1>`	`h1 { color: red; }`	`document.write("Hello!");`

🔹 Simple Example:

<!DOCTYPE html>
<html>
<head>
    <style>
        h1 { color: blue; }
    </style>
    <script>
        function showMessage() {
            alert("Hello, this is JavaScript!");
        }
    </script>
</head>
<body>
    <h1>Welcome to Web Development</h1>
    <button onclick="showMessage()">Click Me</button>
</body>
</html>

✅ HTML creates the heading and button.
✅ CSS makes the heading blue.
✅ JavaScript makes the button show an alert when clicked.

2. Explain the process of setting up a development environment for web development.

To start web development, you need some basic software and tools:

1. Text Editor (for writing code)

Notepad++ (Simple and easy)
VS Code (Popular among developers)

2. Web Browser (for testing webpages)

Google Chrome (Best for development)
Mozilla Firefox

3. Local Web Server (for testing advanced web pages)

XAMPP (For PHP and databases)

4. Steps to Set Up

Install VS Code and a web browser.
Open VS Code and create an index.html file.
Write a basic HTML page and save it.
Open the file in a web browser to see your webpage.

💡 Tip: Always save your file with .html extension before testing.

3. Create a basic HTML page that includes a header, a paragraph, an image, and a hyperlink.

✅ Code for a simple webpage:

<!DOCTYPE html>
<html>
<head>
    <title>My First Webpage</title>
</head>
<body>
    <h1>Welcome to My Website</h1>
    <p>This is my first webpage. I am learning HTML!</p>
    <img src="image.jpg" alt="A beautiful scenery" width="300">
    <br>
    <a href="https://www.google.com">Click here to visit Google</a>
</body>
</html>

💡 Save this as index.html and open it in a browser.

4. How do you style a table using CSS? Create a sample table and apply styles to it.

✅ HTML Table with CSS Styling

<!DOCTYPE html>
<html>
<head>
    <style>
        table {
            width: 50%;
            border-collapse: collapse;
        }
        th, td {
            border: 1px solid black;
            padding: 10px;
            text-align: center;
        }
        th {
            background-color: lightblue;
        }
        tr:nth-child(even) {
            background-color: lightgray;
        }
    </style>
</head>
<body>
    <h2>Student Marks</h2>
    <table>
        <tr>
            <th>Name</th>
            <th>Marks</th>
        </tr>
        <tr>
            <td>Ali</td>
            <td>85</td>
        </tr>
        <tr>
            <td>Sara</td>
            <td>90</td>
        </tr>
    </table>
</body>
</html>

💡 Tip: Use border-collapse: collapse; to remove space between table borders.

5. Describe the different CSS selectors and provide examples of each.

Selector Type	Example	Description
Element Selector	`p { color: red; }`	Styles all `<p>` tags.
Class Selector	`.highlight { color: blue; }`	Styles elements with `class="highlight"`.
ID Selector	`#title { font-size: 20px; }`	Styles an element with `id="title"`.
Group Selector	`h1, h2 { text-align: center; }`	Styles multiple elements together.

✅ Example:

#main {
    color: green;
}
.highlight {
    background-color: yellow;
}

💡 Tip: Use classes when styling multiple elements and IDs for unique elements.

6. Explain the process of creating a responsive web page using CSS.

A responsive webpage adjusts its layout for different screen sizes.

✅ Example using Media Queries:

body {
    font-size: 16px;
}
@media (max-width: 600px) {
    body {
        font-size: 12px;
    }
}

🔹 Explanation:

The font size is 16px by default.
When the screen width is 600px or smaller, the font size reduces to 12px.

💡 Tip: Use flexbox and grid for better responsive design.

7. Write a JavaScript function that changes the background color of a web page when a button is clicked.

✅ HTML + JavaScript Code:

<!DOCTYPE html>
<html>
<head>
    <script>
        function changeColor() {
            document.body.style.backgroundColor = "lightblue";
        }
    </script>
</head>
<body>
    <button onclick="changeColor()">Click to Change Color</button>
</body>
</html>

🔹 Explanation:

The onclick event runs the changeColor() function when the button is clicked.
document.body.style.backgroundColor = "lightblue"; changes the background color.

💡 Tip: You can use "random" colors using Math.random().

8. How do you add animations and transitions using CSS?

✅ Example of a simple animation:

@keyframes move {
    from { left: 0px; }
    to { left: 200px; }
}

.box {
    position: relative;
    width: 100px;
    height: 100px;
    background-color: red;
    animation: move 2s linear infinite;
}

✅ Example of a button with transition:

button {
    background-color: blue;
    color: white;
    padding: 10px;
    transition: background-color 0.5s;
}
button:hover {
    background-color: green;
}

🔹 Explanation:

Animation moves a box from left to right.
Transition smoothly changes button color when hovered.

💡 Tip: Use ease-in-out for smoother effects.

🔥 Conclusion: Learning HTML, CSS, and JavaScript step by step helps in building amazing websites. Keep practicing and experimenting with code! 🚀
