Answer 1

If you want the entire site to be full-width, add this CSS somewhere

<style>
    .container {
        width: 100%;
    }
</style>

But if you only want the content pane, you need to add your own class to the container div holding the main

<!-- Page Content -->
<div class="container containerMain">
    <main role="main">

<style>
    .containerMain {
        width: 100%;
    }
</style>

Or create/buy a skin and use that.
