CSS CSS Basics (2014) Enhancing the Design With CSS Web Fonts with @font-face

Why we have included 'src:' in first two fonts only not other two?

font-family: 'Abolition Regular';
  src: url('../fonts/abolition-regular-webfont.eot');
  src: url('../fonts/abolition-regular-webfont.eot?#iefix') format('embedded-opentype'),
       url('../fonts/abolition-regular-webfont.woff') format('woff'),
       url('../fonts/abolition-regular-webfont.ttf') format('truetype');

why we didn't write src: in front of wolf and truetype?

Look at the ends of the lines: while the first src line ends in a semicolon (meaning it's the end of the declaration), the file paths in the second src: are separated by commas, which means they are all part of a single declaration -- so they're all part of a single "src". The reason you need 2 srcs at all is because Internet Explorer 9 breaks if you add all those extra fonts to the declaration -- so the first src acts like a fallback declaration for the second one. The second one will be used by all newer browsers. Here is a popular go-to for some more info about the @font-face rule.

Thank-you for you answer.
