Adding css stylesheet

Hello!

I  am using a timeline by Knightlab with several 1000 lines of css code. The code is so long, it takes up all the css space in SS, so I wanted to add a .css stylesheet. This is what I did:

1) add a blank page to a folder (my code folder)

2) add text "timeline.css and then link it to the uploaded .css file

3) change the .css link in the original script so that it is the new stylesheet.

Am I missing anything? Will it take a little while to show up? Right now the page looks like it has no css. 

2) add text "timeline.css and then link it to the uploaded .css file

3) change the .css link in the original script so that it is the new stylesheet.

CSS need rel tag, not <script> tag.
