 ####  How Hartija works?
 
 Just use it like normal CSS:
-```sh
+```html
 <link rel="stylesheet" href="print.css" type="text/css" media="print">
 ```
 The "magic" is in  media="print", this CSS file will be used by the browser only when you print. You can also use it inside CSS like: **@media print** { .. }.
 
 Only work you need to do is **hide** the stuff you don't need in the final print. Basically you hide some id and class in the CSS like:
-```sh
+```css
 #navbar, #footer, #someOtherID, .someClass, .otherClass { display : none; }
 ```
