Types of CSS
Welcome to the first section of CSS Mastery! Understanding how CSS is applied to HTML documents is your gateway to mastering styling. In this section, we’ll demystify the three core approaches to CSS implementation—Inline CSS, Internal CSS, and External CSS—with practical examples and clear guidance on when to use each method.
