title: How do I create templates for displaying posts in a category page using Twenty Thirteen child theme?
body: <p>I am trying to setup my category archives in Twenty Thirteen. So far they fetch all the right posts and contain all the neccessary elements. Now I wish to style these elements and also edit the layout. The problem is I don't know where to do this. It is worth noting that this is my very first site and that I am a beginner.</p>
  
  <p>Below is the code from my category.php. I understand that it uses functions to get the data but I don't get where the html/css for these elements is set. </p>
  
  <pre><code>&lt;div id="primary" class="content-area"&gt;
      &lt;div id="content" class="site-content" role="main"&gt;
  
      &lt;?php if ( have_posts() ) : ?&gt;
          &lt;header class="archive-header"&gt;
              &lt;h1 class="archive-title"&gt;&lt;?php
                  if ( is_day() ) :
                      printf( __( 'Dagsarkiv: %s', 'twentythirteen' ), get_the_date() );
                  elseif ( is_month() ) :
                      printf( __( 'Månadsarkiv: %s', 'twentythirteen' ), get_the_date( _x( 'F Y', 'monthly archives date format', 'twentythirteen' ) ) );
                  elseif ( is_year() ) :
                      printf( __( 'Kategoriarkiv: %s', 'twentythirteen' ), get_the_date( _x( 'Y', 'yearly archives date format', 'twentythirteen' ) ) );
                  else :
                      _e( 'Archives', 'twentythirteen' );
                  endif;
              ?&gt;&lt;/h1&gt;
          &lt;/header&gt;&lt;!-- .archive-header --&gt;
  
          &lt;?php /* The loop */ ?&gt;
          &lt;?php while ( have_posts() ) : the_post(); ?&gt;
              &lt;?php get_template_part( 'content', get_post_format() ); ?&gt;
          &lt;?php endwhile; ?&gt;
  
          &lt;?php twentythirteen_paging_nav(); ?&gt;
  
      &lt;?php else : ?&gt;
          &lt;?php get_template_part( 'content', 'none' ); ?&gt;
      &lt;?php endif; ?&gt;
  
      &lt;/div&gt;&lt;!-- #content --&gt;
  &lt;/div&gt;&lt;!-- #primary --&gt;
