First you need to add font to site:

Then you define this font for your element.
Check css docs for this.

You can google it, nothing to do with theme or osclass.
If you do not know what to do with css basics, please, do not modify theme.

Custom modifications are in your hands. You should know what you do, not to ask others to do it. You can find ton of helpful topics on google regarding CSS, you should do some effort to achieve your goals.

You should think about what support means and what is custom development. We have provided support to you and told you where to look and what you need, I hope you do not expect we will do it for you. This is your work. You are not developing products for us as well. You have not paid for custom development, you have paid for product and support.
