Alright. I am already using a child theme. I was a little but confused concerning your answer. Thanks.
I learned very much via your help in this post.

Thanks ??

Thanks, Lorro.
Is there a site where I can find these names (supplementary, site-generator)?

It worked. Thank you.
Do you know how I can reduce the margins of the site?

One quick question before I will try this out: Is the page.php replace when I will update my theme?

Thanks for your answer. And thanks for your hint that it will be overwritten when the theme is going to be updated.
However, I copied the code in a text file and will keep it in mind. You really helped me and I learned a lot! Thanks.

Last question: About the grey lines. Now, that I will keep the footer widget I will have the grey lines, too. Do you know, how I can get rid off this spacer lines?

Ok, I follow your instructions step-by-step, but my changes had not any effect on my website at all.
That’s what I did:
I copied a sidebar.php out of the Twenty Eleven Theme folder. And I renamed it: sidebar-mypersonalfilename.php.
Now I opened the index.php and copied this between the brackets like
<?php get_sidebar(‘mypersonalfilename’); ?>
I uploaded both, but nothing changed. Any idea?

The reason why I do not choose another theme is because I really like to learn something. And I really appreciate the help of all of you. I already learned so much!

Any idea anyone? I really appreciate your ideas concerning this problem ??

No, because I do not know what to put in between the brackets…

This code, I suppose, like I mentioned before. But what I put in there and what else I will need?
<?php get_sidebar(); ?>

Or another question. How can I get rid off the two grey lines in the bottom of the page? And how can I decrease the height of these footer wieget areas?

Ok, thanks. But now slowly, please ??
1) Where do I have my html tag with the css id in my web page?
2) Yes, there is no right sidebar visible. But why? It was there, but after I did something (and I cannot figure out what it was) it disappeared ??
But in my widget confuguration area, I placed a text widget in the main/general sidebar with the image.

Thanks.
Can’t I create another widget area? Between the header and the content?

Ok. That’s the content. I suppose I need to replace this part of the code:
<?php get_sidebar(); ?>
But how? How do I get my text widget (with the image inside) in this sidebar. Sorry, but I don’t get it. I really appreciate your help.

get_header(); ?>

		<div id="primary">
			<div id="content" role="main">

			<?php if ( have_posts() ) : ?>

				<?php twentyeleven_content_nav( 'nav-above' ); ?>

				<?php /* Start the Loop */ ?>
				<?php while ( have_posts() ) : the_post(); ?>

					<?php get_template_part( 'content', get_post_format() ); ?>

				<?php endwhile; ?>

				<?php twentyeleven_content_nav( 'nav-below' ); ?>

			<?php else : ?>

				<article id="post-0" class="post no-results not-found">
					<header class="entry-header">
						<h1 class="entry-title"><?php _e( 'Nothing Found', 'twentyeleven' ); ?></h1>
					</header><!-- .entry-header -->

					<div class="entry-content">
						<p><?php _e( 'Apologies, but no results were found for the requested archive. Perhaps searching will help find a related post.', 'twentyeleven' ); ?></p>
						<?php get_search_form(); ?>
					</div><!-- .entry-content -->
				</article><!-- #post-0 -->

			<?php endif; ?>

			</div><!-- #content -->
		</div><!-- #primary -->

<?php get_sidebar(); ?>
<?php get_footer(); ?>

Ok, now slowly, please ??
This is the content of the index.php. Which part I will have to modify?

<?php
/**
 * Front to the WordPress application. This file doesn't do anything, but loads
 * wp-blog-header.php which does and tells WordPress to load the theme.
 *
 * @package WordPress
 */

/**
 * Tells WordPress to load the WordPress theme and output it.
 *
 * @var bool
 */
define('WP_USE_THEMES', true);

/** Loads the WordPress Environment and Template */
require( dirname( __FILE__ ) . '/wp-blog-header.php' );
