## mj-font

This tag imports fonts.
The tag has effect only if the template uses the font, too. 
The `href` attribute points to a hosted css file; that file contains a `@font-face` declaration.
Example: [https://fonts
.googleapis.com/css?family=Raleway](https://fonts.googleapis.com/css?family=Raleway)

```xml
 <mjml>
   <mj-head>
     <mj-font name="Raleway"
       href="https://fonts.googleapis.com/css?family=Raleway" />
   </mj-head>
   <mj-body>
     <mj-section>
       <mj-column>
         <mj-text font-family="Raleway, Arial">
           Hello World!
         </mj-text>
       </mj-column>
      </mj-section>
   </mj-body>
 </mjml>
 ```
