Event List View Sizing?

Site URL: https://www.futuresoundgroup.com/shows

Hi 

Is there a way to make the list view on Events Page smaller so that it's easier to see more events on loading?  I'm using Brine and the event thumbnail is square, I've tried changing that to 16:9 but it hasn't really made an effective difference.  What I'd like to do is reduce the size of the square thumbnail and all the text on the event listing on that page but not on other pages on the site. 

Is there a way to do this with custom css?

Thanks

Try adding to Page Settings > Advanced > Header

<style>
div.summary-thumbnail {
    padding-bottom: 66.667% !important;
}
div.summary-thumbnail img {
    width: 100% !important;
    height: auto !important;
    top: 0 !important;
    left: 0 !important;
}
</style>

Then save & reload your site.
