<p>I'm using netbeans on ubuntu, I would like to add some fonts to it. Could anyone tell me how this is done ?</p>

If you put it at the bottom, it loads last, hence speeding up the speed that the user can see the page. It does need to be before the final
```
</html>
```
though otherwise it won't be part of the DOM.
If the code is needed instantly though, then put it in the head.
It's best to put things like blog widgets at the bottom so that if they don't load, it doesn't affect the usability of the page.
