Hello @mlevine3@esu.edu

Since the theme itself provides the option for Custom CSS we would like you to remove the Custom CSS plugin that you are currently using.

Whatever Custom CSS you want to add you can add it thorough Custom CSS that the theme provides.

And for the white spacing we need to see your backend credentials cause we need to check by adding custom CSS. It seems that you have lot of custom CSS added. So we are finding it difficult to find the exact solution.

So, if possible send your credential at support[at]wensolutions.com

Hope you understand.

Best Regards!!!

Hello @mlevine3@esu.edu

Ok, to increase height of the header image in mobile version try adding below Custom CSS.

@media only screen and (min-width : 320px) and (max-width : 736px) { 
	#masthead {
    	min-height: 160px !important;
	}

}

Hope this will help to resolve your issue.

Best Regards!!!
