How do you legally obtain and use custom fonts on a website?

To legally obtain and use custom fonts on a website, follow these steps:

1. **Choose Reputable Sources**: Obtain custom fonts from reputable sources such as font foundries, designers, or web font services. Ensure they provide fonts with proper licensing options.

2. **Review Licensing Terms**: Carefully read and understand the licensing terms provided by the font provider. Pay attention to usage rights, restrictions, and any specific requirements outlined in the font license agreement.

3. **Select Suitable License**: Choose the appropriate license for your needs, considering factors like the number of users, domains, or projects, and whether it's for personal or commercial use. Purchase or obtain the necessary license accordingly.

4. **Download Font Files**: Once you've acquired the appropriate license, download the font files provided by the font provider. Make sure to keep a copy of the license agreement for your records.

5. **Implement Fonts**: Use the `@font-face` rule in your CSS stylesheet to import the custom font files and specify font-family declarations for HTML elements. Ensure compliance with font license terms regarding font embedding and usage restrictions.

   ```css
   @font-face {
       font-family: 'CustomFont';
       src: url('path/to/font.woff2') format('woff2'),
            url('path/to/font.woff') format('woff');
   }

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

6. **Display License Information**: Some font licenses require you to display license information or attribution on your website. Follow the font license terms regarding the inclusion of copyright notices or attribution.

7. **Monitor Compliance**: Regularly review your website to ensure continued compliance with the font license terms. Update licenses as necessary if your website's usage changes or expands.

By following these steps and adhering to font license agreements, you can legally obtain and use custom fonts on your website while respecting font creators' rights and intellectual property.
