This CSS code defines the styling for two elements, #outerdiv and #innerIframe, which likely work together to position an iframe within a container (#outerdiv).
#outerdiv { width:756px; height:496px; overflow:hidden; position:relative; }
#innerIframe { position:absolute; top:-116px; left:-430px; width:1280px; height:1200px; }
HTML code
<div id="outerdiv">
<iframe src="https://mail.google.com" id="innerIframe" scrolling="no" sandbox=""></iframe>
</div>
The iframe (#innerIframe) is positioned outside of the visible bounds of the container (#outerdiv) by using negative values for top and left. The large dimensions of the iframe (1280x1200px) exceed the size of #outerdiv (756x496px), and overflow: hidden in #outerdiv ensures that only a portion of the iframe is visible within the container. The positioning of the iframe within the container allows you to control which part of the iframe’s content is displayed in the visible area.
In essence, this setup is likely being used to show a specific portion of a larger content, such as zooming into a section of an embedded page or media.
