We set a global `min-height: 100%` for the body element (a common strategy to allow for background images to fill the viewport), but this is undesirable for iframes where the `window.onresize` is used to programmatically adjust the iframe height. Because `onresize` will fire when the body adjusts itself as per its `min-height: 100%`, in certain situations this will lead to an infinite resizing loop. This is notably visible when: * Rendering the video block when using Firefox: this causes the iframe size to jiggle indefinitely. * Rendering the HTML block when there are empty block elements (such as `<p></p>`) that have a vertical margin set (which happens to be the default to HTML blocks): this will cause the iframe to increase in height infinitely. By adding an inline `min-height: auto` on the wrapping body element, this overrides the Studio-served CSS, and thus fixes the problem.
CMS
===
This directory contains code relating to the Open edX Content Management System ("CMS"). It allows learning content to be created, edited, versioned, and eventually published to the `Open edX Learning Mangement System <../lms>`_ ("LMS"). The main user-facing application that CMS powers is the `Open edX Studio <https://edx.readthedocs.io/projects/open-edx-building-and-running-a-course/en/latest/getting_started/CA_get_started_Studio.html#>`_
