Advam registration 1, create markup, styles for- registration form, section headings and updated margins on header and footer templates.

Nice use of helpers :+1: 

The number should be part of the `h3` though as it's all **the** heading. So something like:

    <h3>
      <span class="panel__hdr__step__no txt-center inline-block align-middle">
        <span class="hide-visually">Step </span>1
      </span> 
      <span class="inline-block align-middle">Personal Details</span>
    </h3>
