Ah, thanks for the clarification. For the nav menu hover, add this and then edit the color code as desired.
.site-header .nav-menu a:hover, .site-header .nav-menu a:focus {
color: #cc0000 !important;
}
On the Resonar demo site, I’m not seeing a scroll down arrow.
Resonar does not have a footer widget area, and adding one to the theme would be a considerable amount of work and require the creation of a Child Theme and a good working knowledge of php scripting.
If you have not hidden the footer credits, you could use the following, which will place text right above the existing footer credits. I’ve included some styling declarations as well that you can use, or delete if you do not use them. This method is best for shorter text additions rather than long ones.
If you need to add more, it would be best to create a Child Theme and then copy over the original footer.php file to the child theme directory and then add that disclaimer directly into the footer html section as a paragraph or div.
