I decided to make a tutorial for my music and stats tabs. You may have to adjust the positioning based on the size of your sidebar, but it's not that hard. I did the codes separately in case you only want one tab.
(For the music tab)
First, paste this html code below <body> in your theme and replace 'PLACE YOUR MUSIC PLAYER HERE' with your music code.
Then, paste this css code below <style type="text/css"> in your theme.
If you notice <ay></ay> on either side of the word 'Music!' it changes the font. And you'll need this code here and under <head>, add this.
<link href='http://fonts.googleapis.com/css?family=Satisfy' rel='stylesheet' type='text/css'>
Ignore and delete <ay> around it if otherwise.
(For the stats tab)
You'll need to paste this html code under <body> and replace 'PUT YOUR ONLINE/HITS/FOLLOWER COUNTERS HERE' with your stat codes.
Finally, paste this css code under <style type="text/css">, remember the same instructions for the font.
If you need any help with coding, message me and i'll help you.
