Nav bar font size

[AmirF194]

How can I change the Nav bar size?
Is it not possible to override it in CSS?
I can not access it with the following :
font_fmt = {'font-class':'h2','font-size':'150%'}

I was able to access the iframe
[data-stale="false"] > iframe[title="hydralit_components.NavBar.nav_bar"] {
/** CSS **/
}
