Need Css help

I have spent about 8 hours over here https://www.w3schools.com/default.asp
I still have yet to figure how to get my Welcome Php floating in the top right hand corner of my Blog. I lost it or it was scattered with the last update. I believe my problem lies within my CSS yet I have added some code to no help. If you know CSS and can check my site and give me an idea if it is in the CSS or Welcome PHP or ?? I would appreciate it. I am going round and round with no fix at all! My page is https://www.netcommercial.net/blog and all my welcome Php is stuffed at the bottom of the page? Thanks in advance.
