## Notes
### Performance
Moving the `href` attribute to the beginning of an element improves compression when GZIP is enabled, because the `href` attribute is used in `a`, `base` and `link` tags.
Example:
``` html
<link href="https://fonts.googleapis.com/css?family=Open+Sans:400,700" rel="stylesheet">
```
