How to change background colour of left menu in Inspinia
<p>The <a href="https://wrapbootstrap.com/theme/inspinia-responsive-admin-theme-WB0R5L90S" rel="nofollow">Inspinia</a> AngularJS framework has a demo <a href="http://wrapbootstrap.com/preview/WB0R5L90S" rel="nofollow">here</a> for those who don't use it.</p>

<p>For the life of me, I cannot see how to change the background colour of the navigation menu on the left. It should be simple, but I just can't find it, even using the Chrome developer console.</p>

<p>[Update] I want to change the color programmatically from AngularJS, what's the best way to do that? Maybe add an Id to the <code>background div</code>?</p>
