## **Basic Structure of an HTML Document**
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>My First HTML Page</title>
</head>
<body>
<h1>Hello, World!</h1>
<p>This is my first HTML webpage.</p>
</body>
</html>
```
---
## **Key Components**
1. **DOCTYPE Declaration:**
Declares the document type and HTML version.
Example: `<!DOCTYPE html>`
2. **HTML Tag (`<html>`):**
The root element that contains all other elements.
3. **Head Section (`<head>`):**
Contains metadata, links to stylesheets, and scripts.
4. **Body Section (`<body>`):**
Contains the visible content of the webpage.
---
## **Common HTML Tags**
### **Headings:**
```html
<h1>Main Heading</h1>
<h2>Subheading</h2>
<h3>Section Title</h3>
```
### **Paragraphs and Text Formatting:**
```html
<p>This is a paragraph.</p>
<b>Bold Text</b>
<i>Italic Text</i>
<u>Underlined Text</u>
```
### **Links and Images:**
```html
<a href="https://www.example.com">Visit Example</a>
<img src="image.jpg" alt="Sample Image">
```

To **change text color in HTML**, you can use the following methods:
---
### **1. Using the `style` Attribute (Inline CSS)**
```html
<p style="color: red;">This text is red.</p>
```
---
### **2. Using `<style>` Tag (Internal CSS)**
```html
<!DOCTYPE html>
<html lang="en">
<head>
<title>Change Text Color</title>
<style>
p {
color: blue; /* Text color */
}
</style>
</head>
<body>
<p>This text is blue.</p>
</body>
</html>
```
---
### **3. Using External CSS File**
1. Create an external CSS file, e.g., `style.css`:
```css
p {
color: green;
}
```
2. Link it to your HTML file:
```html
<!DOCTYPE html>
<html lang="en">
<head>
<link rel="stylesheet" href="style.css">
</head>
<body>
<p>This text is green.</p>
</body>
</html>
```
---
### **4. Using `<font>` Tag (Deprecated)**
```html
<font color="purple">This text is purple.</font>
```
> **Note:** The `<font>` tag is **deprecated** in HTML5, so it's better to use **CSS** instead.
---
### **5. Using Hex Codes or RGB Values**
- **Hexadecimal:**
```html
<p style="color: #ff6347;">This text is tomato color.</p>
```
- **RGB Values:**
```html
<p style="color: rgb(255, 99, 71);">This text is tomato color.</p>
```
- **RGBA for Transparency:**
```html
<p style="color: rgba(255, 99, 71, 0.5);">This text is semi-transparent.</p>
```

### **Which method do you want to explore further?**
Let me know if you'd like examples with gradients, shadows, or animations!
===
Here are examples of **gradients**, **shadows**, and **animations** in HTML and CSS:
---
## **1. Text with Gradient Color**
**Example: Linear Gradient Text**
```html
<!DOCTYPE html>
<html lang="en">
<head>
<title>Gradient Text</title>
<style>
h1 {
background: linear-gradient(to right, red, blue);
-webkit-background-clip: text;
-webkit-text-fill-color: transparent;
font-size: 50px;
}
</style>
</head>
<body>
<h1>Gradient Text</h1>
</body>
</html>
```
**Key Points:**
- **`linear-gradient()`** applies a gradient background.
- **`-webkit-background-clip: text;`** clips the background to the text only.
- **`-webkit-text-fill-color: transparent;`** makes the text transparent, showing the gradient.
---
## **2. Text with Shadow**
**Example: Simple Shadow**
```html
<!DOCTYPE html>
<html lang="en">
<head>
<title>Text Shadow</title>
<style>
h1 {
font-size: 50px;
color: darkblue;
text-shadow: 3px 3px 5px gray; /* Horizontal, Vertical, Blur, Color */
}
</style>
</head>
<body>
<h1>Text Shadow</h1>
</body>
</html>
```
**Example: Glowing Shadow Effect**
```html
<h1 style="color: white; text-shadow: 0 0 10px cyan;">Glowing Text</h1>
```
---
## **3. Text with Animation**
**Example: Color Changing Text Animation**
```html
<!DOCTYPE html>
<html lang="en">
<head>
<title>Color Animation</title>
<style>
h1 {
font-size: 50px;
animation: colorChange 3s infinite; /* Apply animation */
}
@keyframes colorChange {
0% { color: red; }
50% { color: blue; }
100% { color: green; }
}
</style>
</head>
<body>
<h1>Animated Text</h1>
</body>
</html>
```
**Key Points:**
- **`@keyframes`** defines the steps for animation.
- **`animation:`** specifies the name, duration, and repetition.
---
## **4. Moving Gradient Text Animation**
**Example: Gradient Animation**
```html
<!DOCTYPE html>
<html lang="en">
<head>
<title>Gradient Animation</title>
<style>
h1 {
font-size: 50px;
background: linear-gradient(45deg, red, yellow, green, blue);
background-size: 300% 300%;
-webkit-background-clip: text;
-webkit-text-fill-color: transparent;
animation: moveGradient 3s infinite;
}
@keyframes moveGradient {
0% { background-position: 0% 50%; }
50% { background-position: 100% 50%; }
100% { background-position: 0% 50%; }
}
</style>
</head>
<body>
<h1>Moving Gradient</h1>
</body>
</html>
```
---
## **5. Bouncing Text Animation**
**Example: Bounce Effect**
```html
<!DOCTYPE html>
<html lang="en">
<head>
<title>Bouncing Text</title>
<style>
h1 {
font-size: 50px;
animation: bounce 1s infinite alternate;
}
@keyframes bounce {
0% { transform: translateY(0); }
100% { transform: translateY(-20px); }
}
</style>
</head>
<body>
<h1>Bouncing Text</h1>
</body>
</html>
```
---
## **6. Rotating Text Animation**
**Example: Rotation Effect**
```html
<!DOCTYPE html>
<html lang="en">
<head>
<title>Rotating Text</title>
<style>
h1 {
font-size: 50px;
animation: rotate 2s linear infinite;
}
@keyframes rotate {
0% { transform: rotate(0deg); }
100% { transform: rotate(360deg); }
}
</style>
</head>
<body>
<h1>Rotating Text</h1>
</body>
</html>
```
