Small bug after removing headline

I’m using Thesis 1.8 as my theme and found a great thread for “removing” the headlines on each of the separate pages on my website with the exception of the headlines for individual posts. Only problem I’m having now is that in my headline for my posts in the before and after headline area it displays { margin: 0; padding: 0; } and looks like crapola. How can I fix this? I’ve included the original coding I placed in my custom.css to “remove” the headlines.

.custom .headline_area { position:absolute; top:-1500px; left:-1500px; padding:0 }
.custom .hfeed .headline_area { left:0; position:relative; top:0; }
