vbcms css help

[edwinrcollins]

in vbcms.css can I add a class that will override the class below? I have to use the embed code below but in my primary content article preview I need to control the height to get my article content above the fold.

I am not the best in css and I figured someone in here would tell me if it is possible.

<div class="getty embed image" style="background-color:#fff;display:inline-block;font-family:'Helvetica Neue',Helvetica,Arial,sans-serif;color:#a7a7a7;font-size:11px;width:100%;max-width:594px;"><div style="padding:0;margin:0;text-align:left;"><a href="http://www.gettyimages.com/detail/466127890" target="_blank" style="color:#a7a7a7;text-decoration:none;font-weight:normal !important;border:none;display:inline-block;">Embed from Getty Images</a></div><div style="overflow:hidden;position:relative;height:0;padding  :79.966330% 0 0 0;width:100%;"><iframe src="//embed.gettyimages.com/embed/466127890?et=eK-IiJ_SSlRdfnC0dn8lDA&viewMoreLink=on&sig=CvWl3JDZlR41oKH_9vPTmL8lj0Vq-aJou_18LfFBblA=&caption=true" width="594" height="475" scrolling="no" frameborder="0" style="display:inline-block;position:absolute;top:0;left:0;width:100%;he  ight:100%;margin:0;"></iframe></div><p style="margin:0;"></p></div>
