What best practices should be followed when using iframes to integrate external content into a web page?

When using iframes to integrate external content into a web page, it is important to ensure that the source of the iframe is secure and trustworthy to prevent security vulnerabilities such as clickjacking or cross-site scripting attacks. It is also recommended to set the height and width attributes of the iframe to prevent layout shifts and maintain a consistent user experience. Additionally, consider using the sandbox attribute to restrict the capabilities of the content within the iframe for added security.

&lt;iframe src=&quot;https://www.example.com&quot; width=&quot;100%&quot; height=&quot;500&quot; sandbox=&quot;allow-same-origin allow-scripts&quot;&gt;&lt;/iframe&gt;
