Space where tags used to be after blogs

Hello!

I need to remove the empty space after my blogs. It’s the space that contained tags until I added this to the custom css: “.post-tags {display: none;}”. Here is a link to a screenshot of what that empty space looks like now:

At the end of the blog I add the horizontal line. And then there is the empty space where tags were before. Just want to get rid of the space easily! A custom css would be great but please let me know: how can I do it?

Thanks!
