Header Image AND Title

You can set the logo as a background image with css.

If your theme does not have an area for custom css you need to install a css plugin or create a child-theme.
Change the URL to point at your logo.

.site-branding {
    background: url("https://s.w.org/about/images/logos/wordpress-logo-notext-rgb.png");
    background-repeat: no-repeat;
    background-size: contain;
    background-position: 15% 20%;
}

The other way would mean hacking a core php file and would require a child-theme.

Great, thanks! I’ll give it a try.

Hello!

With Sugar & Spice it’s either the logo OR Website name and tagline. CSS is one way to go, but I think it would be easier to simply create an image that contains both your logo and tagline.
If you decide to go the CSS route please remember that you should never edit theme files directly, only through some CSS Manager plugin or child theme.

Thanks, Alex! I created a new image/logo combo and love it.
Thanks again!
