soleiltan on "How do I remove author, date tags from pages and posts?"

I am using the OXYGEN
Magazine WordPress Theme.

I copied the CSS file into the custom CSS and added the following code to the end:

.entry-author-link { display: none; }
.entry-permalink { display: none; }
.entry-date { display: none; }
.entry-meta { display: none; }

It is still not working!
