CSS - Bootstrap Scrollspy - how to change color according section background
<p>I had a bootstrap nav with scrollspy - fixed and without background color.</p>

<p>When I scroll down I have different sections, with different backgrounds colors.</p>

<p>Then I need a solution to change de font color of nav to contrast with the section background.</p>

<p>I not so expert in CSS - then, sorry if its a dummy question - but there is a way to do this?</p>

<p>Change the font of nav for each section?</p>

<p>AND, its possible to hide navbar in some sections (like home section, where I have another navigation menu)</p>

<p>tks!</p>
