Internal CSS Last Updated : 24 Jun, 2024 Comments Improve Suggest changes Like Article Like Report Internal CSS is a method for defining CSS styles directly within an HTML document. It's particularly useful for applying unique styles to a single web page, and it's embedded within the <style> element located in the <head> section of the HTML file. How to Use Internal CSS ?To use internal CSS, you need to include CSS rules within a <style> tag inside the HTML document's <head>. This allows you to define styles by selecting HTML elements or classes and applying styling rules within the tag. The styles defined by internal CSS apply only to the specific web page where they are included. Syntax: <style> /* Internal CSS starts here */ </style>Example: Here is the basic example of using internal CSS. HTML <!DOCTYPE html> <html> <head> <title>Internal CSS</title> <style> /* Internal CSS */ h1 { color: green; font-size: 50px; text-align: center; } p { color: blue; font-size: 25px; line-height: 1.5; text-align: center; } </style> </head> <body> <h1>GeeksforGeeks</h1> <p>A Computer Science Portal..!</p> </body> </html> Output: Example 2: In this example, we are using internal CSS to style a page with a green heading, a blue paragraph, and a centered red button that changes color on hover. The button also includes a link to the GeeksforGeeks website. HTML <!DOCTYPE html> <html> <head> <title>Internal CSS</title> <style> /* Internal CSS starts here */ h1 { color: green; text-align: center; font-size: 50px; } p { font-size: 25px; color: blue; text-align: center; } .container { text-align: center; } .btn { background-color: red; color: white; border-radius: 5px; padding: 10px 20px; text-decoration: none; } .btn:hover { background-color: #0056b3; } </style> </head> <body> <h1>GeeksforGeeks</h1> <p>A Computer Science Portal..!</p> <div class="container"> <a href="https://www.geeksforgeeks.org/" class="btn">Click Me</a> </div> </body> </html> Output: Advantages of Internal CSSLocalized Styling: Keeps styles within the HTML file, avoiding conflicts with other pages and making it easier to manage styles at the local level.Higher Specificity: Internal CSS has higher specificity than external CSS, allowing easier overriding of external styles within the same HTML file.Performance: Reduces HTTP requests, potentially enhancing performance as no additional CSS files need to be loaded.Ease of Implementation: Simple to use and implement, making it easy to quickly apply styles to a single page.Disadvantages of Internal CSSRepetition: Styles must be repeated in multiple HTML files if the same styles are needed across different pages.Increased File Size: Embedding CSS in HTML increases the file size of the HTML document.Reduced Reusability: Limited code reusability across different web pages.Limited Management: Managing styles across multiple pages can become difficult without a centralized stylesheet.By understanding the strengths and limitations of internal CSS, you can make informed decisions about when and how to use it effectively in your web projects.
