Big Gap Above Embedded Videos

Hi there,

I’ve recently changed my theme to Gridiculous and it’s looking pretty good so far, except for one big problem. There’s a large gap that has suddenly appeared above every video that i’ve embedded in past posts. Nothing has changed in the “Edit” window, there’s the usual space between the text and the embed code, but now all videos have a pretty big space above the videos – not below. Here’s a link so that you can see what i’m talking about: https://www.thereelword.net/new-teaser-trailer-hbo-the-leftovers/

Any help would be greatly appreciated, since I post many videos on the site.
