If content is hidden on a web page using a CSS hidden directive (consider this example of hiding the Sharepoint 2013 Share button with CSS).
What techniques allow the user to circumvent that and access the function being hidden? In other words, in essence click the "forbidden" button anyway.
In this case I am particularly interested in content which is made possible on the website via javascript in some way, rather than simply hiding a link or form submission which seems trivial to reveal.
