So some people tell me "the titles there's no difference between them"; I recently upgraded to Atahualpa 3.4.4. But I think what font size <h1> <h2> <h3> <h4> <h5> <h6> are too big. How to Change it?

I look A.T.O. but i dont find a option to change.
I look Css.php, both old and new Athahualpa version, but I dont khow php. I whant aprox
<h1> <h2> <h3> <h4> <h5> <h6> arer elatively more small.

Old Version

PHP Code:

 {font-size: 2.15em; font-weight: bold;}
h2 {font-size: 1.85em; font-weight: bold;}
h3 {font-size: 1.6em; font-weight: bold; }
h4 {font-size: 1.4em;}
h5 {font-size: 1.2em;}
h6 {font-size: 1em;} 


New Version

PHP Code:

/*
h1 {font-size: 2.15em; font-weight: bold;}
h2 {font-size: 1.85em; font-weight: bold;}
h3 {font-size: 1.6em; font-weight: bold; }
h4 {font-size: 1.4em;}
h5 {font-size: 1.2em;}
h6 {font-size: 1em;}
*/

h1, h2, h3, h4, h5, h6 {
  color: #000;
  display: block;
  /* fixed for Non-PCs without Photoshop CS2+ */
    font-smooth: always;
}

h1 { font-size: 34px; line-height: 1.2; margin: 0.3em 0 10px; }
h2 { font-size: 28px; line-height: 1.3; margin: 1em 0 .2em; }
h3 { font-size: 24px; line-height: 1.3; margin: 1em 0 .2em; }
h4 { font-size: 19px; margin: 1.33em 0 .2em; }
h5 { font-size: 1.3em; margin: 1.67em 0; font-weight: bold; }
h6 { font-size: 1.15em; margin: 1.67em 0; font-weight: bold; } 


you could change them there or use a CSS Insert to override them

h1 { font-size: 34px; line-height: 1.2; margin: 0.3em 0 10px; } 
h2 { font-size: 28px; line-height: 1.3; margin: 1em 0 .2em; } 
h3 { font-size: 24px; line-height: 1.3; margin: 1em 0 .2em; } 
h4 { font-size: 19px; margin: 1.33em 0 .2em; } 
h5 { font-size: 1.3em; margin: 1.67em 0; font-weight: bold; } 
h6 { font-size: 1.15em; margin: 1.67em 0; font-weight: bold; }

just change the font-size to what ever you want

Thankyou, very much.
