Line blocks not showing up

I had put in some custom css to make line blocks disappear so I could have certain text background filled and other not on a blog post. Now, I am trying to redesign the blog posts to just have a line separating content but when I put the line in, nothing shows up. When I put a line on a page that doesn't have a white background, then it shows up. I don't know how to change the color. Is there custom css to change line color? TIA!

Can you share your website URL and an example page where the line is added but not visible? What do you currently have in Custom CSS? Have you tried temporarily removing it?

The site is https://friendsofminnesotaorchestra.org/. The lines don't show up under the November Newsletter blog post. I don't remember what CSS I added that removed line blocks, so I'm not sure how to remove it.

If you go in the dashboard under design and Custom CSS you should be able to find the code that's added to your website. If you can copy that all in this chat we can try and find the problem and help you remove it.

I can't find any line blocks on the page or blog, I also can't see any reference to line blocks in the Custom CSS. Can you share a screen recording of this not working or something else that might help me understand what's happening?

Sorry, wrong website css. Here is the correct one:

#myBtn {

   height: 50px;
   display: none;
   position: fixed;

   padding: 10px 10px 10px 11px;
   border-radius: 50%;
   box-shadow: 1px 1px 5px #000;
   /* Change the hex code in the next line to change background color */
   background-color: #a4a4a4;

I can't see any CSS there that would remove the line block.
