Hi Bas,

I am sorry, but unfortunately, that's not possible to apply CSS to the specific image, you can only globally update the images styles. You can try either one to match your blog images.

[gist type="php"]
#eb .eb-blog-grid-image {
background-position: top center;
}
[/gist]
or
[gist type="php"]
#eb .eb-blog-grid-image {
background-size: contain;
background-color: #dedede;
}
[/gist]
