Hello mortals!

I have a question regarding Wordpress posts.

In my new theme, I have these new buttons as you see below. These buttons are awesome!

They add like a box around some text or link, to make it pop out more.

So I was just wondering, if anyone of you know: Is it possible to add more of these buttons, like a Wordpress Plug-in, or something (I do not care, if it is not free).
