CSS Selector for 1st blog post entry within blog page

Hey, I'm trying tweak the css of the 1st blog post on the blog page.

Trying the following:

.w-blog-list > w-blog-entry-h:first-child {
    background: red;
}

which isnt working

A blog entry looks like this

<div class="l-main"> <div class="l-submain"><div class="l-submain-h g-html i-cf"><div class="g-cols offset_default"><div class="three-quarters"><div class="w-blog columns_1 imgpos_atleft"> <div class="w-blog-list"><div class="post-744 post type-post status-publish format-standard hentry category-blog tag-content-marketing tag-storytelling w-blog-entry"> <div class="w-blog-entry-h"><a class="w-blog-entry-link" href="http://test.ingenuitydigital.co.uk/the-re-emergence-of-storytelling-in-content-marketing/"><span class="w-blog-entry-preview"><span class="w-blog-entry-preview-icon"><i class="fa fa-file-o"></i></span></span><h2 class="w-blog-entry-title"> <span class="w-blog-entry-title-h">The Re-emergence of Storytelling in Content Marketing</span> </h2></a> <div class="w-blog-entry-body"> <div class="w-blog-meta"><div class="w-blog-meta-date"> <i class="fa fa-clock-o"></i> <span>16th May 2014</span> </div></div><div class="w-blog-entry-short">As with any new channel, when the online world first appeared businesses rushed to get something, anything online....</div><a class="w-blog-entry-more g-btn color_default size_small outlined" href="http://test.ingenuitydigital.co.uk/the-re-emergence-of-storytelling-in-content-marketing/"><span>Read More</span></a></div></div></div><div class="post-201 post type-post status-publish format-standard has-post-thumbnail hentry category-blog tag-digital-marketing tag-display-advertising tag-ppc tag-remarketing w-blog-entry"> <div class="w-blog-entry-h"><a class="w-blog-entry-link" href="http://test.ingenuitydigital.co.uk/make-your-ppc-perform/"><span class="w-blog-entry-preview"><img width="350" height="334" src="http://test.ingenuitydigital.co.uk/wp-content/uploads/2014/02/Make-Your-PPC-Perform-350x334.jpg" class="attachment-blog-small wp-post-image" alt="Make Your PPC Perform" /></span><h2 class="w-blog-entry-title"> <span class="w-blog-entry-title-h">Make your PPC Perform</span> </h2></a> <div class="w-blog-entry-body"> <div class="w-blog-meta"><div class="w-blog-meta-date"> <i class="fa fa-clock-o"></i> <span>4th February 2014</span> </div></div><div class="w-blog-entry-short">If you’re not seeing ROI on your PPC campaigns – why not talk to ­us?
