If you open one of your HTML pages with a suitable text editor, and search for "new NavBar" you will find the section of the page which generates the navbar on-the-fly. It calls a javascript function NavBar with a load of parameters, which look largely like gobbledegook, and determine what the navbar will look like.
If you are at all familiar with CSS you will notice that if you replace all instances of "\n\t" with a line break and a tab, you will be looking at standard CSS information. The "\n\t" is there because you can't pass a literal carriage return / tab pair to a javascript function, you have to use the escape characters \n and \t.
In other words, if you expand:
.navbar {\n\tfont-family: 'Courier New', Courier, monospace, serif;\n\tfont-size: 1.1em;\n\tcolor: #AFAA9F;\n\tmargin: -2px 0 0 0px;\n\tline-height: 20px;\n\tpadding: 5px 0 12px 0;\n\tfont-weight: bold;\n\tbackground-image: url(home
files/navfill-v2-21.jpg);\n}
it looks something like this:
.navbar {
font-family: 'Courier New', Courier, monospace, serif;
font-size: 1.1em;
color: #AFAA9F;
margin: -2px 0 0 0px;
line-height: 20px;
padding: 5px 0 12px 0;
font-weight: bold;
background-image: url(home
files/navfill-v2-21.jpg);
}
So to change the font size, just find the font-size bit and change it:
.navbar {\n\tfont-family: 'Courier New', Courier, monospace, serif;\n\tfont-size:
0.9em;\n\tcolor: #AFAA9F;\n\tmargin: -2px 0 0 0px;\n\tline-height: 20px;\n\tpadding: 5px 0 12px 0;\n\tfont-weight: bold;\n\tbackground-image: url(home
files/navfill-v2-21.jpg);\n}
Likewise any of the other properties.
I can't believe Apple didn't spend the few hours required to present the user with the options to change this stuff. The fact that it would have been SO easy makes me believe there has to be more to it than that; some sort of policy. Upgrade carrot? Who knows.
Sorry if this is less than 100% clear. I'm the wrong side of a fine cabernet.
