Remove Name, Date, Category, No Comments Meta data from blog post

Replies: 0

I am trying to remove all meta data from my blog posts. I tried to use the following CSS code and it works on my customiser preview but doesn’t seem to save when I publish… Does anyone have advice for this?

.post__meta .post-categories {
	display:none;
}
.post-author.meta-wrapper,
.post-comment-link.meta-wrapper{
    display:none;
}
.post-date
{
  display: none;
}

Thanks!
