<?php /* The loop */ ?>
<?php while ( have_posts() ) : the_post(); ?>
<a href="<?php the_permalink(); ?>" style="color:#000; text-decoration:none;">
<div class="col-sm-4 col-md-3 col-xs-6 for_cat_thumb_info">
<div class="row for_thumb_cat">
<?php if ( has_post_thumbnail()) {the_post_thumbnail('full',array("class"=-->"thumb_cat"));} ?>
</div>
<div class="line_cat">
</div>
