Do more formats in @font-face determine more http requests?

问题

Consider a similar css code:

@font-face {
    font-family: 'MyFont';
    src: url('../fonts/MyFont.eot');
    src: local('Proxima'), url('../fonts/MyFont.woff') format('woff'), url('../fonts/MyFont.ttf') format('truetype'), url('../fonts/MyFont.svg') format('svg');
    font-weight: normal;
    font-style: normal;
}

Does this code determine more HTTP requests to download all the formats or does the browser choose the best supported format?

回答1:

Nope, browser will choose one compatible format. Feel free to add as many sources as you like :)

回答2:

No, only one will be used. You can test it for example with firebug or google console and check the list of all requests that has been made (network tab)
