How to access images in css file in symfony template

Question

In the html file i can access the images folder using asset function but in my css i am not able to us e images

background-image:url(../images/back.png)

{% stylesheets 'css/*' %}
<link href="{{ asset_url }}" rel="stylesheet" media="screen" />
{% endstylesheets %}

How to fix that

Answer 1

This is something that always puzzles me as well! Anyway there is a cssrewrite assetic filter that should help you to solve this problem detecting and rewriting urls in css scripts (anyway, even using this, you may need to change urls in your css).

Answer 2

I use this:

background-image: url(/bundles/yourbundle/images/pic.png)

Works without cssrewrite filter.
