How to change the title font?

[mibzman]

I would like to change the title font, where is that modifiable?

Which title do you want to change, blog title, or post title? You can add the style in the file arsnippet.css

This is the title I'm referring to, sorry if I wasn't clear!

Referring to arsnippet.css, where is that file located?

Please see this. The final folder structure is as follows:

your_site_folder
| -- source
| -- css
        | -- arsnippet.css
| -- js
        | -- arsnippet.js

An example code in the arsnippet.css

.brand-logo {
	font-family: "Times New Roman", Times, serif;
}
