home – counts of posts

hi,

first off all, my english isn’t so good but i’ll try my best.

i’ve tried to make a bootstrap html theme to a wordpress theme, without good php and wordpress skills (i used a videotraining by v2b), and it works well so far. There is just one thing i can’t change.. in the middle of my home.php i embedded posts from category 1. i want that there are just 3 posts or 6 posts, but wordpress shows only 5. I placed 6 posts (published) in category 1.

Link

and here’s the code

<div class="row">
					<?php
					$posts = get_posts('category=1');
					foreach ( $posts as $post ) : setup_postdata( $post );
					?>
                    <div class="col-md-4">
                        <div class="templatemo-service-item">
                            <div><div class="meta-nu">Geschrieben von: <span class="txt_orange"><?php the_author_link();?></span> am <?php the_date(); ?></div>
                                <?php if ( has_post_thumbnail() ){ $thumbnail = wp_get_attachment_image_src( get_post_thumbnail_id(), 'thumbnail');?>
								<img src="<?=$thumbnail[0];?>" alt="icon" />
								<?php } ?>
                                <span class="templatemo-service-item-header"><?php the_title();?></span>
                            </div>
                            <p><?php the_excerpt();?></p>
                            <div class="text-center">
                            	<a href="<?php the_permalink();?>"
                                	class="templatemo-btn-read-more btn btn-orange" role="button">weiterlesen &raquo;</a>
                            </div>
                            <br class="clearfix"/>
                        </div>
                        <div class="clearfix"></div>
                    </div>
                    <?php
					endforeach;
					wp_reset_postdata();
					?>
                </div>

hope anyone can help… regards
