Difference in character styles?

I'm still familiarizing myself with the basics of Japanese, but it doesn't seem like the Hiragana lessons match up with some Hiragana tables I have for reference. Are there different ways of writing characters? I noticed a big difference between the lessons 'Ki' and the Hiragana tables. Is there a formal and informal way of writing these characters? Thank you in advance.

There may just be a difference in font used by your computer to draw those characters. This might help you :) http://www.firegrubs.com/images/chokochoko/hiraganahandwriting.pdf

That's very helpful, thank you! I'll bookmark this! The link also shows my issue, too. For Ki and Sa, the print example shows a full semi-circle for the last stroke, but the written area shows an example of just a line; if that makes sense? The same goes for Ko: the video example given in the lesson looks like two arced lines, but the print shows something different. Maybe i'm over complicating this. Is there just a difference between print and hand written and they both mean the same thing?

Both the videos here and the link that I gave you are correct. I'd incline to say that those in the video are a bit more precise, however, it all depends on the handwriting that the person has "adopted" :). Don't sweat it, either one is ok. Just go with the ones that are easier for you to write :D.
