Upon direct access, the website below demonstrates full responsiveness:
However, when embedded within an iframe, its responsiveness falters and fails to adapt to the browser width:
iframe {
display: block; /* iframes are inline by default */
border: none; /* Reset default border */
height: 100vh; /* Viewport-relative units */
width: 100vw; /* Viewport-relative units */
}
<div class="iframeContainer">
<iframe src="https://sherpasoftware.com/">
</iframe>
</div>

Various responsive iframe solutions were attempted without success on this specific site. It was observed that the target site applies a fixed width of 1093px when accessed through an iframe, contrary to its behavior when directly accessed and resized. This unique behavior hinders the implementation of standard responsive methods, indicating a discrepancy in how the site responds based on the method of access - directly or via an iframe.
The target site appears to detect differences when accessed through an iframe as opposed to direct access, although the exact reason remains unclear.
How can this issue be resolved to ensure the iframe behaves responsively like a traditional browser, adapting smoothly to changes in size?
Contrast the above unresponsive JSFiddle example, accessible both directly and via an iframe, with the following example which maintains responsiveness regardless of access method. The sole distinction lies in the URL.
iframe {
display: block; /* iframes are inline by default */
border: none; /* Reset default border */
height: 100vh; /* Viewport-relative units */
width: 100vw; /* Viewport-relative units */
}
