Inline CSS applies styles directly to HTML elements using the style attribute, allowing for quick, unique styling without external stylesheets.
- Quick Application: Ideal for rapid, one-off style adjustments.
- High Specificity: Overrides other CSS rules due to its specificity.
- Limited Reusability: Not suitable for applying the same styles to multiple elements.
Syntax:
<tag style = " "></tag>
HTML
<html>
<body>
<p style="color: blue; font-size: 18px;">
This is a paragraph styled with inline CSS.
</p>
</body>
</html>
- Inline Styling: The style attribute within the <p> tag applies CSS directly to the paragraph, setting the text color to blue and font size to 18 pixels.
- Immediate Effect: This method allows for quick, element-specific styling without the need for external or internal CSS.
When to Use Inline CSS?
- Applying Unique Styles: Ideal for styling individual elements without affecting global styles.
- Testing or Debugging: Useful for quick style adjustments during development.
- Email Templates: Ensures consistent styling across various email clients.
- Dynamic Styling with JavaScript: Allows for programmatically changing styles based on user interactions.

Best Practices for Using Inline CSS
- Use Sparingly: Reserve inline styles for unique, one-time adjustments to individual elements.

- Prioritize External Stylesheets: For consistent and maintainable styling, define common styles in external CSS files rather than inline.
