Is it possible to blur images on individual blog posts?

Hey, y'all! I'm new to Squarespace and am working on a photography blog. I have SFW and NSFW images and I was wondering if there is a way to assign blogs with an "NSFW" tag to blur until being clicked. I know this is probably a long shot. I'd also be happy if there's a way to do it manually by inserting a code block into the individual blog post, but I couldn't work that out either.   

Thanks for any help you can provide!

I actually figured it out on my own! Answering for folks who might find this in the future. this is the code I ended up using on my site's custom css to blur the tag "nude".
