Custom CSS issue

I have some trouble when using the Custom CSS in Attitude Themes options.

I added just this code to change the color of certain texts but nothing happen:

body, input, textarea {
	color: #400A06;
}

h1, h2, h3, h4, h5, h6 {
	color: #BF1F12;
}

more-link {
	color: #18FF7C;
}

It was working before so I tried to desactivate all other plugins I installed but I still have the same problem… An idea?
