This behaviour is arguably not always appropriate - generally, only interactive controls/content should be focusable. If the list element or any of its children are not "tabbable" (accessible by keyboard keys such as the a and button elements or any elements with a positive tabindex), a tabindex of 0 will be added by default to the list item. Accessibility considerations for amp-listīy default, adds a list ARIA role to the list element and a listitem role to item elements rendered via the template. Notice however, that the typical placement of elements at the bottom of the document almost always guarantees that the AMP runtime can resize them. If the AMP runtime cannot satisfy the request for the new height, it will display the overflow element when available. If needs more space after loading, it requests the AMP runtime to update its height using the normal AMP flow. ![]() Loading is triggered using normal AMP rules depending on how far the element is from the current viewport. ![]() The request is always made from the client, even if the document was served from the AMP Cache.
