Change the font of a Page tab

[lewis200]

I have the need to change the color of a Page tab, as well as reformat the text (or change the text?)
This is the Javascript I use in the onLoad:
?>

#id_StyleViewNew_form6 { Background-color: yellow; } <?php This works well for the color  I can not however get the syntax for changing the font, or font size or text value. Here by the way id what I get when I do an inspect of the HTML

TimeLine Any guidance is appreciated. TY Lew
