I'm trying to export a page in PDF format with Snappy Laravel. I have the page with all the CSS and it works great and looks great, but when I try to export it, my page is downloaded in pdf format but without any CSS. Here is the code and what I have already tried:

**Controller:**

```
$pdf = PDF::loadView('admin.userReport');
$pdf->setOption('enable-javascript', true);
$pdf->download('myFileName.pdf');

```

**Head:**

```
<link href="{{ asset('/css/app.css') }}" rel="stylesheet"/>

```

**PS:** I tried to put the absolute path to the CSS file, but it doesn't work either.
