    src: url('../fonts/glyphicons-halflings-regular.eot');
    src: url('../fonts/glyphicons-halflings-regular.eot?#iefix') format('embedded-opentype'),
          url('../fonts/glyphicons-halflings-regular.woff') format('woff'), 
          url('../fonts/glyphicons-halflings-regular.ttf') format('truetype'),
          url('../fonts/glyphicons-halflings-regular.svg#glyphicons_halflingsregular') format('svg');
}
