Question: This is the content of my base.html.twig file:

```
<html lang="en" class="no-js">
<head>
    <title>{% block title %}Welcome!{% endblock %}</title>
    <link rel="icon" type="image/x-icon" href="{{ asset('favicon.ico') }}" />
    <meta charset="utf-8">

    <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
    <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1">

    {% block stylesheets %}
        <link href="{{ asset('css/bootstrap.css') }}" rel="stylesheet" type="text/css">
    {% endblock %}

</head>

```

This is the path of my file: `C:\xampp\htdocs\myproject\app\Resources\assets\css\bootstrap.css`.

I am note sure if my path is correct I am a totally newbie to this. Can someone point me and explained step by step how can include a css file ? thx in advance

[UPDATE] Here is my structure of my project[![enter image description here](https://i.stack.imgur.com/23TZv.png)](https://i.stack.imgur.com/23TZv.png)

Answer: 
In project folder add to 
`src/AppBundle(or name of your bundle)/Resources/public/css/bootstrap.css`

and then in twig template do this:

```
{{asset('bundles/name_of_your_bundle/css/bootstrap.css')}}

```

This will generate url for your file in `src/your_bundle/Resources/public/css/bootstrap.css`

I suggest you to read this blog: <http://tutorial.symblog.co.uk/index.html> 
There is series how to create blog in symfony2.
firstly, including a css file has got nothing to do with php or symphony

```
 <link href="css\bootstrap.css" rel="stylesheet" type="text/css">

```

if you are using this to include the css file then your php file must be in the assets folder, if its outside any other folder, just say its in the app folder then you need to include those folders as well in the path.

```
<link href="Resources\assets\css\bootstrap.css" rel="stylesheet" type="text/css">

```

as you said you are totally newbie, and i see you are trying symphony. i would like to advice you to start with HTML and CSS, then PHP and and move to symphony after that. If you do not want to face any problem in the future.
