I am trying to access the elements of Google Sheets sidebar I developed, using Chrome console. for example - getting width of an element:
$("#elemID").css("width");
where
elemID is the dom element ID of a certain element in the page.
However, the element is not found and $("#elemID") returns null.
This is happening for all sidebar elements, none of them is found in the console. see image.
Why is that? is there a way to achieve it?
