From what I understand, the Tumblr buttons at the top right of any Tumblr site are auto-inserted via iFrame. This means I cannot directly delete these buttons by editing the HTML. But I want them gone. I don't want my website to be an advertisement for the blogging platform.
How can I remove the "Follow" (or "Unfollow") and "Join Tumblr" (or "Dashboard" + Mail) buttons from my site?
