css - Is it possible to style posts in octopress according to its tags? -

i need style posts in octopress have tag 'old' differently. like, show title , no image in archives , keep them separated! how can this? (note : there 1,500 posts old tag)

you use tags css classes:

<ul>   {% post in site.posts %}             <li><a href="{{ post.url }}" class="tags {{ post.tags | join:' ' }}">{{ post.title }}</a></li>        {% endfor %} </ul> 

that way can style link via css tag.
