🟢 Inline, Internal, External CSS
CSS can be applied to HTML in three main ways: Inline, Internal, and External. Each method has its own use case and importance depending on the situation.1.Inline CSS
Definition: Styles are applied directly to an individual HTML element using the style attribute.
🔧 Example:
<p style="color: red; font-size: 18px;">This is an inline styled paragraph.</p>
🖼️ Output Behavior:
The paragraph text will be red and sized at 18px.
🔎 Use Case:
Useful for quick changes or overriding other styles.
Not recommended for large-scale styling or maintainability.
2. Internal CSS
Definition: Styles are written within a <style> tag inside the <head> section of an HTML document.🔧 Example:
<!DOCTYPE html>
<html>
<head>
<style>
h1 {
color: blue;
}
p {
font-size: 16px;
}
</style>
</head>
<body>
<h1>This is a heading</h1>
<p>This is a paragraph with internal styling.</p>
</body>
</html>
🖼️ Output Behavior:
The heading becomes blue.
The paragraph has a 16px font size.
🔎 Use Case:
Good for single-page websites or testing styles quickly.
3. External CSS
Definition: Styles are written in a separate .css file and linked using the tag in the HTML .
🔧 Example:
CSS file (styles.css):
body {
background-color: #f0f0f0;
font-family: Arial, sans-serif;
}
h2 {
color: green;
}
HTML file:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="styles.css">
</head>
<body>
<h2>This is a styled heading</h2>
</body>
</html>
🖼️ Output Behavior:
Background becomes light gray.
Font changes to Arial.
Heading is green.
🔎 Use Case:
Best practice for styling modern websites.
Allows reuse of styles across multiple pages.
Makes styles easier to maintain and update.
| Method | Placement | Best for |
|---|---|---|
| Inline | In the tag (style="...") | Quick, one-off styles |
| Internal | In <style> in the <head> | Small or single-page sites |
| External | In a .css file | Large projects, reusability & maintainability |
🔐 External CSS is the most recommended method for scalability and clean code.
