How can the use of iframes affect scrolling behavior within a webpage?

When using iframes within a webpage, it can affect scrolling behavior by creating separate scroll bars within the iframe itself, making it difficult for users to scroll the entire page. To solve this issue, you can set the scrolling attribute of the iframe to "no" to disable the scroll bars within the iframe and allow the main webpage to scroll smoothly.

<iframe src="https://www.example.com" width="100%" height="400" scrolling="no"></iframe>
