@nicolej: Go to => Appearance => Customize => Additional CSS and add the following CSS Code.
/* To change color of menu links */
.site-navigation a {
color:#123456;
}
/* To change color of menu links */
.site-navigation a:hover {
color:#123456;
}
/* To change the thickness of border of menu items */
.site-navigation .current_page_item > a, .site-navigation .current-menu-item > a, .site-navigation .current_page_ancestor > a, .site-navigation .current-menu-ancestor > a {
border-bottom:6px solid;
}
/* To change background of Featured Content section */
#featured-content-section {
background-color:#123456;
}
You can change the color and border size according to your choice.
And let me know which paragraphs you want to be highlighted.
Let me know if this works out!
Kind Regards,
