Making child-stylesheet work correctly

I have made a child-theme of Responsive.

Currently I have:
header.php
style.css

While my child styles.css is found and being used, I find that I can’t just change stuff like #wrapper{} – I have to use #container #wrapper{} before anything is changed. On the contrary, it’s no problem changing #container{} on its own. Same goes for example: #header. It needs #container #header.

Child theme: wp-content/responsive/responsive-child
Child css: wp-content/responsive/responsive-child/styles.css

In child header for the stylesheet it says:

<link rel=”stylesheet” href=”<?php bloginfo(‘template_url’); ?>/style.css” type=”text/css” media=”screen” title=”no title” charset=”utf-8″>

This loads the parent css file. Have tried fiddling with it, but no succes.

Here is my site: rubinreklame.dk

What am I missing?
