Switching a section to full width

Hi,

My content is wrapped within wrapper, content, content-wrap and finally container clearfix. What I'm trying to do is switch a part of the code out of these wrappers in order to have it full-width. The problem is that when I do this, it either doesn't work properly no matter how much I try to mess with css, or the top slider is being stretched down through all the content for some reason. (I used the index-wedding as a starting point for this page).

For example, I'm trying to make the container with images/lyon.jpg full-width as well as the google map, but not the rest.

Here's part of the code :

    <section id="content">

        <div class="content-wrap">

            <div class="container clearfix">

                <div id="section-location" class="heading-block center topmargin page-section">
                    <h2>Le Lieu</h2>
                </div>

                <blockquote class="quote">
                    <p class="quote-text">Capitale des Gaules...</p>
                </blockquote>

                <div class="container" style="padding-left: 0; padding-right: 0; margin-bottom: 40px">
                    <img src="images/lyon.jpg" style="max-width: 97%; margin-left:auto; margin-right:auto">
                    <div class="centeredover overtitle">LYON</div>
                </div>

                <blockquote class="quote blockquote-reverse nobottommargin">
                    <p class="quote-text">... Berceau de l'EDARA.</p>
                </blockquote>

                <div style="margin-top: 30px">
                    <div class="titlelocation">Complexe sportif de La Doua</div>
                    <div class="center"><em>18 Rue des sciences, 69100 Villeurbanne</em></div>
                    <div id="google-map1" style="height: 300px; margin-top: 30px" class="gmap"></div>
                </div>
