How to include a font .ttf using CSS?

I have a problem with my code. Because I want to include a global font for my page and I downloaded a .ttf file. And I include it in my main CSS but my font wont change.

Here's my simple code:

@font-face {
    font-family: 'oswald';
    src: url('/font/oswald.regular.ttf');
}

html, body, div, span, applet, object, iframe, h1, h2, h3, h4, h5, h6, p, blockquote, pre, a, abbr, acronym, address, big, cite, code, del, dfn, em, img, ins, kbd, q, s, samp, small, strike, strong, sub, sup, tt, var, b, u, i, center, dl, dt, dd, ol, ul, li, fieldset, form, label, legend, table, caption, tbody, tfoot, thead, tr, th, td, article, aside, canvas, details, embed, figure, figcaption, footer, header, hgroup, menu, nav, output, ruby, section, summary, time, mark, audio, video {
    margin:0;
    padding:0;
    border:0;
    font-size:100%;
    font:inherit;
    font-family: oswald;
    vertical-align:baseline
} 

I don't know where did I go wrong. Can you help me with this? Thanks.

Only providing .ttf file for webfont won't be good enough for cross-browser support. The best possible combination at present is using the combination as :

@font-face {
  font-family: 'MyWebFont';
  src: url('webfont.eot'); /* IE9 Compat Modes */
  src: url('webfont.eot?#iefix') format('embedded-opentype'), /* IE6-IE8 */
       url('webfont.woff') format('woff'), /* Modern Browsers */
       url('webfont.ttf')  format('truetype'), /* Safari, Android, iOS */
       url('webfont.svg#svgFontName') format('svg'); /* Legacy iOS */
}

This code assumes you have .eot , .woff , .ttf and svg format for you webfont. To automate all this process , you can use : Transfonter.org.

Also , modern browsers are shifting towards .woff font , so you can probably do this too : :

@font-face {
  font-family: 'MyWebFont';
  src: url('myfont.woff') format('woff'), /* Chrome 6+, Firefox 3.6+, IE 9+, Safari 5.1+ */
   url('myfont.ttf') format('truetype'); /* Chrome 4+, Firefox 3.5, Opera 10+, Safari 3—5 */
}

Look for browser support : Can I Use fontface

Did you try format?

@font-face {
  font-family: 'The name of the Font Family Here';
  src: URL('font.ttf') format('truetype');
}

Read this article: http://css-tricks.com/snippets/css/using-font-face/

Also, might depend on browser as well.

You can use font face like this:

@font-face {
  font-family:"Name-Of-Font";
  src: url("yourfont.ttf") format("truetype");
}

I know this is an old post but this solved my problem.

@font-face{
  font-family: "Font Name";
  src: url("../fonts/font-name.ttf") format("truetype");
}

notice src:url("../fonts/font-name.ttf"); we use two periods to go back to the root directory and then into the fonts folder or wherever your file is located.

hope this helps someone down the line:) happy coding
