I suggest you take a closer look at the code and strip out as much as you can to see what is actually necessary to get where you are going. Here is a fiddle with some cleaned up code that does what I think you are going for. Hopefully it helps.
HTML
<header class="container global-header">
<div class="inner-w">
<div class="large-logo-wrap">
<img src="http://placehold.it/400x300" />
</div>
</div>
</header>
<section class="container section01">
<div class="inner-w">
Middle - arbitrary set height - I suggest you let the content decide the height
</div>
</section>
<section class="container section02">
<div class="inner-w">
Other section - arbitrary set height
</div>
</section>
CSS
*, *:before, *:after { /* get your box model so that padding and margins go inside the box instead of outside, and add to the overall size of the box */
-moz-box-sizing: border-box;
-webkit-box-sizing: border-box;
box-sizing: border-box;
}
body {
margin: 0;
}
.container { /* things the sections have in common */
width: 100%;
float: left;
}
.inner-w {
max-width: 700px;
margin-right: auto;
margin-left: auto;
padding: 1em;
border: 1px solid rgba(0,0,0,.05); /* just so you can see */
/* by using an inner div in your container... you allow yourself to maintain a background-color across the whole page if you wish. If you don't want that, then you just style the inner div for each section with the background color */
}
.global-header {
background-color: lightblue;
text-align: center; /* centers inline, and inline-block elements (logo) */
}
.large-logo-wrap {
display: inline-block;
max-width: 8em; /* set max image size */
}
.large-logo-wrap img { /* responsive image */
display: block;
width: 100%; /* fits whatever you set the wrapper to */
height: auto;
}
.section01 { /* arbitray section */
background-color: rgb(229,225,209);
color: rgb(0,0,0);
min-height: 234px; /* if you absolutly must - choose a height... use min */
}
.section02 { /* arbitray section */
background-color: rgb(29,25,29);
