Loading Spinner Styling Update Suggestions

[jasjs1]

Hey AverageTechBro! I noticed that the loading animation was touching the top of the webpage. I have a few suggestions for that:

1. Make it centered
2. Make it bigger, so that the user can easily see that it's loading.

I provided the loading animation 2 times :)

Keep up the great work with SWEProjects, and the YouTube channel!
