The code that i found is also editable and equal what i found with the editor in WordPress (Appearance – editor), or am I wrong?

I paste your code in the end of this code shown above, but it didn’t change a thing. What should i do?

@andrew Nevins
Also thank you for helping me.
I was reading it and found out if i change anything my saves will lost when there is an update. But would it keep my changes if i use the editor in WordPress? Or should i download a specific plug-in?
