Change custom front page font in responsive theme

Hi there,

I have changed the type of font and the font colour of my site with the following code in my > CSS styles

body, div, p, h1, h2, h3, h4, h5, h6 {
  font-family: georgia;
  color: #7a4900;
}

But this hasn’t changed the body font on my custom homepage, though it changed the title. Not sure how to change this- I’ve had a few tries but as a newbie can’t firgure it out.

Any help much appreciated
