Do I need to use Safari for this? A lot of what we added in the CSS tab in the work space did nothing in my preview. Is there a away I can post what I have? I am passing all the test but my workspace preview is coming out completely different than in the video.

You can use any browser you wish.

As a word of advice... download every single browser available, as it helps to break your own code by testing in multiple browsers.

If you wish to show your code you can share your workspace, or check the Markdown Cheatsheet for examples on how to post your code.
