Fed up with that WordPress top admin bar? Maybe it’s just me but It just seems to get in the way when I want to see what my blog really looks like. Well lucky you it’s super easy!
From your WordPress admin click “Add New” link under plugins. Then do a search “hide tool bar” the first option should be “Hide Admin Bar 2013” this is it! Just add it and activate and wallah (or whatever that magic term is lol).
The other way is in the code:
You can remove the WP toolbar for everyone all the time by adding
add_filter( 'show_admin_bar', '__return_false' );
To functions.php in your theme.
To remove the faint line, go into white.css, find the block:
#header {
background-color:transparent;
background-image:none;
border-bottom:1px solid #E5E5E5;
}
and remove the line border-bottom:1px solid #E5E5E5;
