I'm hoping someone could give me some advice on problems I'm constantly having with this program. For starters, I don't know anything about web design. I just picked this software because it came up as recommended in a Google search. I use it to keep a friend's website updated as a favor to him.

A lot of times when I make changes and save them, the different font sizes look OK when I use the preview feature in the software. I also open the changed pages in my web browser directly from the html file on my hard drive. Everything looks fine and is laid out correctly. But when I upload the page with the FTP program and then go to look at the changed pages online, the different font sizes are missing. Also, sometmes some of the text I added simply isn't there.

For the font size problem, I'm attaching screenshots of what I'm talking about. The top image is what it looks like when I view the copy on my hard drive, and the second image is what it looks like when I upload the page and view it online.

Any advice would be greatly appreciated. Thank you!
