Simple Price Grid Component

Hi,

This looks pretty good. There's just an issue with html headings. It's really important that headings go in order and don't jump levels. So a h3 belongs to a h2, a h4 belongs to h3 etc.

Also, headings must make sense as stand alone headings in a document outline, a d text cannot only be in a span/div.

So this should be changed from

<div class="price">
    <h2>$29</h2>
    <span class="pm">per month</span>
</div>

To this

<div class="price">
    <p>
        <span class="price-highlight" >$29</span>
        <span class="pm">per month</span>
    </p>
</div>
