Color on post for single post

The headline on my posts page looks great. (https://globalz.com/blog/)
But, on the single post page, I have white on white. (https://globalz.com/2018/08/19/crazy-rich-asians-luxury-goods/)
I need to either have the post title on single post pages become blue. Or, I need to put a blue bar behind the white text. Can you help me to solve either one? I have tried all of the below in my CSS.

I would also love to get rid of that vertical line on the page! THANK YOU

(BTW, I would be perfectly happy to design a page for the single blog posts. But, I do not see where in the Enfold menu I would name that page and indicate where the single blogs would go.)

#top.single .post .post-title h1 a {
text-align: left;
width: 100%;
color: rgb(45, 92, 136);;
outline-color: none;
}

#top .post-title h1 a {
color: #2d5c88;
text-shadow:none;
}

#top .alternate_color.title_container .main-title a {
color: #2d5c88;
text-shadow:none;
}

#top.single .post-title h1 a {
color: #2d5c88;
text-shadow:none;
}
