This is so crazy!

This is so crazy! I changed my blog style the other day, and I am pretty much satisfied with it. The crazy thing is -when I click on the Name of the blog, everything looks correct (all titles in pink). When I click on the name of a post, the titles are all in black! I keep checking my settings and designs over and over, and they all show up PINK! What in the world is going on? Also, I cannot make any of my writing divide into paragraphs. It works just fine in the text mode of writing, but then on the blog - everything is all jammed together! When I just did a 'preview' of this post, all of the titles are in black. They are supposed to be pink. I just do not know what is going on. Like I said, this is so crazy!!!!!!
