Removing tags and other things from post page

Try this:

.pull-left {
    display: none;
}
.category-tag {
    display: none;
}

that worked, thank you but how can i get it to display what category the post is in only? I still dont want author name, date/time ect

Replace the .category-tag with one of the following.
.icon-tags
.icon-folder-open

both only removes the icons and not the actual words

Hello,
Thank you for message.

For such changes you need to edit content.php and index.php files
