WTF!!

Ok, so yesterday I tried to do some new things to my blog and just about none of them worked, I am getting frustrated!!!!! I found the code to make it "snow" on my site...actually I changed the snow flake to leaves...and it looks great in the preview and I saved the changes and republihed the damn post, but it won't show up on the site. Has anyone else had this problem? I also have a code to change the curser.....so that it is trailed by an image..and again it showed on the preview but not on the site. WTF???? Any suggestions are welcome!!
p.s. thank goodness I am going to get my massage today!
