Change Horizontal Line Color entire site

I want to change the color of all the horizontal lines on the site I'm designing in 7.1. 

I used this code:

.sqs-block-horizontalrule hr {
  background-color: #1999ce;
}

It worked on the home page, but not on the other pages.

Let us see your current site

As far as I can tell your code is working across your site.

If it still is not can you give us a specific page where the effect is not working?

Are you referring to this

You don't necessarily have to use custom CSS to solve this issue. You can customize Section Themes and change the Line Block Line Color.

In the color editor you can enter #1999ce or hex(#1999ce).

Thanks all!
