Change color of the stipes on website

So I’ll be happy to take a closer look at what options are available. When I open the site, I only see two small horizontal dashes on the left side. At the top and bottom of your sidebar. Are these the lines in question? If not, please take a screen shot of what you’re seeing so I can have a better understanding. That can be linked here with something like https://snipboard.io/

I also noticed that there are 2 “home” links in the site menu.

Hi,

Thank you for your reply.
Those lines are the ones I mean indeed.
You can see them on other pages as well.

Is there an option to make them white?

Adding this piece of code should do it:

.site-footer::before {
    background: white;
}

.page-header::after {
    background: white;
}

That worked great, thank you so much!

You’re very welcome!
