Hi
Don’t change css files, just put the following CSS into “OldCar options > Custom code > Custom CSS”
#sidebar,
#sidebar h1,
#sidebar h2,
#sidebar h3,
#sidebar h4,
#sidebar h5,
#sidebar h6,
.media .bd h4 a,
.media .bd h3 a,
.primary-navigation > ul > li > a,
.sidebar-widget ul li.menu-item a,
#sidebar footer,
.sidebar-widget li a {color:#000;}
.sidebar-widget #s{border:1px solid #ddd;}
And add the following javascript code into “OldCar options > Custom code > Custom javascript”
jQuery(document).ready(function($){
$('#sidebar .social-icons').addClass('social-icon-inverse');
});
