How do I align Font Awesome icons to the right?

Question

I'm trying text-align: right in my CSS, but text-align is not moving it for some reason. I want the website title left aligned and the icon right aligned on the same line. Here's what I am trying.

Answer 1

text-align will align the text within the element which you are assigning it to, which doesn't do anything in an inline-block element like this (since that's just as wide as its contents). Use float: right; instead of text-align: right

Answer 2

If text-align: right is not working, try float: right.
