Adding tag line to header

Good day,

I would like to use the blank space below the menu to add an image or text, how would I go about doing this? I tried using the Tag Line but I am guessing that when one uses the logo it will not allow the tag line to work? Maybe move the tag line so it shows up beside the logo?
site is www.stopitmn.org

Thanks for you help

Hi,
Also when scrolling down by one click the site header jumps or glitches

Hello,

That wouldn’t be really possible without using a child theme and making some changes. Because the space is limited, using a logo won’t allow displaying a tagline also.

I’m not seeing any glitches and I’m not sure I understand what you mean by one click.
