        the_content('&lt;a style="margin-left: 5px;text-transform: uppercase;display: inline-block;" href="'. get_permalink($post-&gt;ID) . '"&gt; '. __( 'Leggi Tutto' , 'color-theme-framework' ) .'&lt;/a&gt;',true,'');
      }   
      else if ( $use_excerpt == 'Excerpt' &amp;&amp; $excerpt != '' ){
        the_excerpt('',FALSE,'');
        echo '&lt;a style="margin-left: 5px;display: inline-block;" href="' . get_permalink($post-&gt;ID) . '"&gt;' . __('Leggi Tutto', 'color-theme-framework') . '&lt;/a&gt;';
