• HTML is like the content of a book. It provides chapters, headings, and paragraphs. Without this content, there’s no story or information.
• CSS is the book’s formatting: the cover design, font choices, margins, and spacing. It makes the book pleasant to read, but it doesn’t change the actual content.

Example:

HTML (Book Content):

htmlCopy code<h1>Chapter 1: Introduction</h1>
<p>This is the first chapter of the book.</p>

CSS (Book Formatting):

h1 {
  font-size: 36px;
  color: darkred;
}
p {
  font-family: 'Arial', sans-serif;
  line-height: 1.5;
}

In this case:

• HTML gives the book its chapters and paragraphs.
• CSS determines the typeface, font size, and line spacing to enhance readability.
