Remove white space between thumbnail tiles (blog)

Basically I've been able to remove my blog title and reduce the horizontal spacing between each blog thumbnail (therefore, my images are touching horizontally). 

However, I want my thumbnails to also touch vertically. (See image for reference). As described In the squarespace tutorial, there is always some white space. 

How can I get rid of such white space?

Thank you.

yes sorry for the delay.

Thank you. Please try this custom CSS:

/* hide blog article spacers */
.blog-basic-grid .blog-article-spacer {
  display: none;
}
