Twentyten-removing admin text and footer

make a backup copy of your theme files before editing

if you insert these styles at the end of style.css, there should be no side effect on any header or menu tabs:

.entry-utility {display:none; }
.entry-meta {display:none; }

you can do it the hard way and edit loop.php and locate and remove the code there:
around line 135:

<div class="entry-meta">
				<?php twentyten_posted_on(); ?>
			</div><!-- .entry-meta -->

and from line 148:

<div class="entry-utility">
				<?php if ( count( get_the_category() ) ) : ?>

all the way down to (inclusive):

<?php edit_post_link( __( 'Edit', 'twentyten' ), '<span class="meta-sep">|</span> <span class="edit-link">', '</span>' ); ?>
			</div><!-- .entry-utility -->

2.
either:
#site-info { display: none; }

or edit footer.php and delete:

<div id="site-info">
				<a href="<?php echo home_url( '/' ); ?>" title="<?php echo esc_attr( get_bloginfo( 'name', 'display' ) ); ?>" rel="home">
					<?php bloginfo( 'name' ); ?>
				</a>
			</div><!-- #site-info -->

——–
the black line:
in style.css;
replace the border-top: 4px solid #000; with border-top: none; in the following style:

#colophon {
	border-top: 4px solid #000;
	margin-top: -4px;
	overflow: hidden;
	padding: 18px 0;
}

Oh my! thank you for your help… the second option is a little confusing to me… I inserted

.entry-utility {display:none; }
.entry-meta {display:none; }

at the very end of my Style.css document…

it looks like this:

@media print {
body {
background: none !important;
}
[Resr if CSS moderated as per the Forum Rules.]

Nothing changed… Am I putting it in the wrong place?

THANK YOU so much for your help!

Try placing it before @media print.

THANK YOU SOOOO MUCH!

I REALLY appreciate the help!

It worked:)
