The "Submit Comment" button for me looks very much different from how a normal button is supposed to look. It's square and has an ugly shade of color to it and seems to not really have any style associated with it. And for the life of me I cannot figure why it doesn't look like a normal button and I can't figure out what is telling the button to look like this. There is absolutely nothing in my stylesheet telling the button to do this.
Here is a picture of said button:
I am using the minimalistic1.5 1.0 theme by the way.
