🎯 The CSS Property: `font-family`

The font-family property in CSS is used to specify the typeface (font) of an HTML element.

✅ Basic Syntax:

selector {
  font-family: "Font Name", fallback-font, generic-family;
}

selector: The element to which the style applies (e.g., p, h1, .title)
"Font Name": The preferred font
fallback-font: Optional secondary fonts
generic-family: A generic fallback like serif, sans-serif, or monospace

🧾 Example:

HTML:

<p class="custom-text">This text uses a custom font.</p>

CSS:

.custom-text {
  font-family: "Georgia", "Times New Roman", serif;
}

In this example:

The browser first tries Georgia.
If unavailable, it tries Times New Roman.
If both fail, it defaults to a generic serif font.

🌐 Using Web Fonts (e.g., Google Fonts)

To use a custom web font like Roboto, you can import it from Google Fonts:

Step 1: Add the font link in `<head>`:

<link href="https://fonts.googleapis.com/css2?family=Roboto&display=swap" rel="stylesheet">

Step 2: Apply it with CSS:

body {
  font-family: 'Roboto', sans-serif;
}

💡 Common Generic Font Families

Generic Family	Description
`serif`	Fonts with decorative strokes (e.g., Times New Roman)
`sans-serif`	Clean, modern fonts without strokes (e.g., Arial)
`monospace`	Each letter takes equal space (e.g., Courier)
`cursive`	Script-style fonts
`fantasy`	Decorative or playful fonts

🧠 Tips for Using `font-family`

Always specify fallback fonts to ensure consistent appearance across devices.
Use quotation marks if the font name has spaces (e.g., "Open Sans").
Pair fonts with care — balance readability and aesthetics.

<!DOCTYPE html>
<html lang="en">

      font-family: 'Open Sans', Arial, sans-serif;
    }
  </style>
