What causes an iframe to have no scrolling?

An iframe is commonly used on web pages to embed content from other sources, such as videos and images. When used properly, an iframe can help make webpages more interactive and user-friendly. However, users may experience issues with an iframe when it does not have scrolling capability. Without scrolling capabilities, an iframe can be difficult to navigate or read the content inside of it.

There are a few main causes for why an iframe might have no scrolling. One cause could be that the webpage is not properly configured to support scrolling. For instance, some browsers may not support some HTML coding needed for scrolling in an iframe. In other cases, the page layout could be such that improper scaling has caused the content in the frame not to fit correctly on the page.

Another common cause of having no-scrolling in an iframe is the use of overflow: hidden CSS attribute code within the iFrame tags or within the styling of any element within or outside of the iFrame itself. When this attribute is added to elements outside or inside of an iFrame (such as a div container) it will override any attempt at making an iFrame scrollable, because it specifies that all overflow (in this case scrollbars) must be hidden from view.

Finally, another possible cause is using fixed sizes for your iFrames instead of setting them at 100% width and height values so they can scale appropriately with its parent container size; without allowing them to scale automatically with its parent element length, you may find that you're always dealing with a cut off frame with no way to scroll around inside of it and explore whatever lies beyond your viewport's edges.
