How to add jquery.css file in Twig? I am working on a project and the plug in I installed won't work because I don't know how to add the jquery.css file needed. 

What I did is to add the file with a &lt;link&gt; command but it's still not working.

Any help would be great. 

    {% block body %}
&lt;link type="text/css"  href="{{ asset('home/workspace/fermate/src/CtrlBln/HomepageBundle/Resources/public/js/Minimal-jQuery-Image-Viewer-with-Image-Preloading-ABigImage/bigimage.jquery.css')}}" &gt; 
&lt;div class="page-sidebar"&gt;
    {% for link in entity.getSidebarImages() %}
        {% if link.image.isFoto() %}            
            &lt;a href="{{ app.request.basepath }}/{{ link.image.getWebPath() }}"&gt;         
                &lt;img src="{{ app.request.basepath }}/{{ link.image.getWebPath("thumbnail_250") }}" alt="{{ link.image.title }}"&gt;                        
                &lt;div class="sidebar-description"&gt;
                    {{ link.image.description|raw }}
                &lt;/div&gt;  
            &lt;/a&gt;        
        {% else %}
            &lt;div class="sidebar-item sidebar-link-item"&gt;
                &lt;a href="{{ app.request.basepath }}/{{ link.image.webpath }}"&gt;

                 &lt;img src="{{ app.request.basepath }}/{{ link.image.getPreview() }}" /&gt;
                &lt;/a&gt;
                &lt;div class="sidebar-title"&gt;
                    &lt;a href="{{ app.request.basepath }}/{{ link.image.webpath }}"&gt;
                      {{ link.image.title|raw }}
                    &lt;/a&gt;
                &lt;/div&gt;
            &lt;/div&gt;
        {% endif %}
    {% endfor %}    
&lt;script&gt;
$(function(){
    $(this).abigimage();
});   
&lt;/script&gt;
&lt;/div&gt;
{% endblock %}

    {% block body_javascripts %}
        {% javascripts output='aBigImage.js'
        '@CtrlBlnHomepageBundle/Resources/public/js/Minimal-jQuery-Image-Viewer-with-Image-Preloading-ABigImage/abigimage.jquery.min.js'    
        %}
        &lt;script type="text/javascript" src="{{ asset_url }}"&gt;&lt;/script&gt;
        {% endjavascripts %}
    {% endblock %}
Is asset() a Twig macro you've defined?

Are you sure you're just not looking for the global url() method instead?
