Only display css-class to Administrator

I wanted to hide a css class from all users except for administrators. I'm using this as a workaround for editing the blog post title, since the ability to edit it from the post's settings was recently deprecated in Squarespace 7.1.  This will enable me to edit the blog post title in the administrator edit screen, but won't display the block to users.

This is the code I'm currently using to hide the title from the Blog Post:

.blog-item-wrapper .blog-item-top-wrapper{display:none}

body:not(.sqs-edit-mode) .blog-item-wrapper .blog-item-top-wrapper{display:none}
