Do you want to change it from the app (objective-c) or the html?

You could create a javascript function inside your html file which changes the font (by changing a class on the body tag for example).

If you want to change it from the app you can call the function with:

[webView stringByEvaluatingJavaScriptFromString:@"changeColor('red')"];

something like this should work.

CSS

.red{
   color:#f00;
}
.green{
   color:#0f0;
}
.blue{
   color:#00f;
}

JS

function changeColor(colorClass){ // red, green or blue
    document.body.className = colorClass; 
}
