how to hide content in html?
I have a website that is primarily used in K-12 schools. I have some social media buttons on it like Facebook 'like' and Pinterest 'pin it'. However, I'd like to have these buttons be hidden....where you have to click once on something (like an image that is covering them up but disappears when clicked....or a tab that just sort of scrolls away to reveal the buttons behind it). The reason for this is because these sites are usually blocked in schools (I realize there's probably nothing I can do about this) and these buttons look kind of ugly when they're blocked (it'll show a question mark or or something in place of the button in these cases). However, I do want the people who do not have them blocked to be able to access and see them easily.
I am in search of a simple solution to this where the buttons wouldn't be immediately visible until you click on something.
