How can CSS be used to achieve scrolling content on a website instead of frames or iframes?

To achieve scrolling content on a website without using frames or iframes, you can use CSS to create a scrollable container for the content. This can be done by setting the `overflow` property of a container element to `auto` or `scroll`. This will allow the content within the container to overflow and be scrolled through by the user. ```html <!DOCTYPE html> <html> <head> <style> .scroll-container { width: 300px; height: 200px; overflow: auto; border: 1px solid #ccc; } </style> </head> <body> <div class="scroll-container"> <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec auctor sapien ac nisi venenatis, vel luctus justo ultricies. Nullam nec elit eget nulla luctus tristique. Proin sed leo id ex tempus malesuada. Sed nec tortor ac ante ultrices ultricies.</p> </div> </body> </html> ```
