Title font

I want a different font for title.
I try edit this css, but doesnt work:
.col-md-4 col-sm-8 col-xs-12

Do you can help me?

Hello there,

Just for information, customizing the site’s look by editing the theme’s core stylesheet isn’t recommended to do. Because once the theme is updated, all files will be overwritten, so modifications will be lost. You have to apply custom CSS via the customizer, go to Appearance > Customize > Additional CSS. Then insert this code:

.site-title {
  font-family: Futura, sans-serif;

Adjust the font family value to meet your requirement. You might be interested to check this CSS font stack for your reference.
