What is web font face?

With the introduction of css3, we are able to use custom fonts in our web pages. Before CSS3, our web development was limited with the use of very few number of font family. With the @font-face rule, web/UI developers do no longer have to use one of the “web-safe” fonts. What helps to use custom fonts in our web applications is the ‘@font-face’ css rule.

What is @font-face rule in css?

The @font-face rule in css3 allows custom fonts to be loaded on a webpage. Once the font family is added to a style sheet, the rule instructs the browser to download the font from where it is hosted, then display it as specified in the CSS.

How to add the @font-face rule in css?

Following css snippet is an example for @font-face rule usage.

@font-face {
    font-family: 'open_sansregular';
    src: url('opensans-regular-webfont.eot');
    src: url('opensans-regular-webfont.eot?#iefix') format('embedded-opentype'),
         url('opensans-regular-webfont.woff2') format('woff2'),
         url('opensans-regular-webfont.woff') format('woff'),
         url('opensans-regular-webfont.ttf') format('truetype'),
         url('opensans-regular-webfont.svg#open_sansregular') format('svg');
    font-weight: normal;
    font-style: normal;
}

Explanation for the css web font face

For demonstration purpose I am using open_sansregular font.
In the new @font-face rule, the first line define the name of the font (e.g. open_sansregular). Then the following lines point to the font file. Here, we can see different formats of fonts, like eot, woff2, woff, ttf and svg. These different formats are used, based on the browser support. ‘eot’ for internet explorer, ‘woff2’ for super modern browsers, ‘woff’ for modern browsers, ‘ttf’ for Safari, Android and iOS, and the last ‘svg’ for legacy iOS.

/*Adding with @ import css rule* /
@import url(fonts.css);
/*adding to main stylesheet*/

@font-face {
    font-family: 'open_sansregular';
    src: url('fonts/opensans-regular-webfont.eot');
    src: url('fonts/opensans-regular-webfont.eot?#iefix') format('embedded-opentype'),
         url('fonts/opensans-regular-webfont.woff2') format('woff2'),
         url('fonts/opensans-regular-webfont.woff') format('woff'),
         url('fonts/opensans-regular-webfont.ttf') format('truetype'),
         url('fonts/opensans-regular-webfont.svg#open_sansregular') format('svg');
    font-weight: normal;
    font-style: normal;
}

Note that you have added the path properly.

When ever you want to use a particular font for particular element, you can use the font family in the following way.

.myElement {
    font-family: 'open_sansregular';
}
/*fall backs*/
.myElement {
    font-family: 'open_sansregular', arial;
}

It is always preferable to use fall backs. In any case, if the custom font is not loading or not found, browser will render with the fall back font. So, that the UI does not break.
