Make a
Bzoink account (optional), take a survey on there, click "Get the Code" button, and then click the big blue link.
Press open the inspect element console (F12) and search for signup_box in the search bar. Right-click the signup_box node and click the "Edit as HTML" button. Press Ctrl+A to select all of the contents of it, then Ctrl+C to copy it.
Now, go to SpaceHey to make a blog post (this will only work in blogs I'm pretty sure?) Above the area where you can input text is a button that says "WYSIWYG", click this to switch it to HTML, paste what you just copied by pressing Ctrl+V.
Above what you just pasted, put this line of code:
<style>#signup_box{background-color:#dbf3fc;color:#000;}</style>
Then post your blog post and it should work just fine! :D
