Let's say you want all the text on your web site to be in the Open Sans font. Is it enough to write,
html, body { font-family: "Open Sans"; font-size: 16px }
Or do I have to (in addition to the above) import Open Sans from google fonts?
In other words, do I really need to add a stylesheet from google fonts, e.g.
<link rel="stylesheet" href="https://fonts.googleapis.com/css?family=Open+Sans" type="text/css">
Summary
What I'm really asking is, do I need to include the google fonts Open Sans stylesheet to format text in Open Sans? Or does Open Sans already come with most web browsers?
I would think that Open Sans comes with most web browsers. I would think that most web browsers have all the font files for standard fonts like Open Sans.
