Site title/tag line how to center change font

this will center the logo. I’m not sure about the tagline.
.site-branding {
float: none;
text-align: center;
}

.site-title a {
color: transparent;
}

Hi greg_res,

Yes you can make the site title and tagline centre by the solution given by Sophia above.

Add the code in your theme’s style.css file.

You can do it by adding the below code in your Child Theme‘s style.css file or by using the My Custom Css Plugin to add the below custom code

.site-branding {
    float: none;
    text-align: center;
}

But I am not sure what do you mean by center aligning the categories, may be a screenshot or a link to the website will help.

You can change the fonts in Appearance > Customize >Fonts

Hope it helps!

Thanks
