I will add to the answer of Sasha Omelchenko a little bit of information that will make your life easier when working with custom fonts:
A). Look closely optional. There are tools for debugging.
For example in chrome dev tools (F12 in chrome):
one). Inspect the item (Ctrl + Shift + C or the corresponding button).

2). We watch it computed styles
3). Scroll to the bottom and see what font the browser has rendered in fact and where it was taken. And do not measure "by eye".

B). First you need to connect a googlofont for a quick copy-paste, and then experiment.
To do this in google phone right above the plus sign "select this font".

A dropout will appear on the bottom right,
you need to click on it, there will be a connection address and default style, you can make ctrl + c / ctrl + v and not make mistakes in the font name or font connection address.
