Make the "Powered by Bearblog" thing disappear.
IMPORTANT NOTE.
TO QUOTE THE OFFICIAL DOCUMENTATION:
It is considered very shitty to use CSS to hide the Made with Bear footer. If you have upgraded or are a contributor to the project it's okay (although it would be awesome if you left it in), however for free users this will be reset automatically (or manually).
The only reason why I'm doing it is so I can make my own link to bearblog in the footer or somewhere else, I love Bearblog and I want to credit it. Please, always do, in one way or another.
Making that "Powered by Bearblog" thing that appears at the bottom go away is kind of hard, but it's doable.
A friend helped me with this and here is what she came up with:
body > footer > span:last-of-type {
display: none;
It doesn't work with all base themes and it does have a tendency to randomly break but it tends to do the job.
