💡 Example: Using Web Safe Fonts in CSS

Here’s how you can apply a web-safe font stack in your CSS styles:

body {
  font-family: "Verdana", "Geneva", sans-serif;
  font-size: 16px;
  line-height: 1.6;
}

🔍 Explanation:

• "Verdana": Primary font
• "Geneva": Fallback if Verdana is unavailable
• sans-serif: Generic fallback if neither is available

📏 Best Practices for Using Web Safe Fonts

✔️ Always include a fallback: Don’t just rely on one font — use at least two named fonts + a generic type.
✔️ Consistent sizing: Some fonts are naturally smaller/larger — test cross-device.
✔️ Avoid too many font stacks: Stick to 2–3 across your site for consistency and load speed.
✔️ Consider accessibility: Use fonts that are easy to read, especially for users with visual impairments.
