如何在不重复wordpress自定义帖子的情况下循环到两个不同的DIVS

this is the code of my custom post.I am not so expert in php.So Please help me in this matter.

<?php $featuresitems=new WP_Query(array( 'post_type'=>'scbleftfeatures' )); ?>

<?php while( $featuresitems->have_posts()) : $featuresitems->the_post(); ?>

<div class="col-md-6 left-grid">
  <div class="features-grid1">
    <div class="feature">
      <h4><?php the_title(); ?></h4>
      <?php the_content(); ?>
    </div>
    <div class="icon5">
      <?php the_post_thumbnail('features_icon_size'); ?>
    </div>
    <div class="clearfix"></div>
  </div>
</div>

<div class="col-md-6 right-grid">
  <div class="features-grid1">
    <div class="feature">
      <h4><?php the_title(); ?></h4>
      <?php the_content(); ?>
    </div>
    <div class="icon5">
      <?php the_post_thumbnail(); ?>
    </div>
    <div class="clearfix"></div>
  </div>
</div>
<?php endwhile; ?>

</div>

Question is a little vague but I'm assuming what you actually want to do is just change the classes left-grid and right-grid for every second div. In that case you don't have to repeat the whole divs, just change the classes. This can done with help of a "counter" ($i).

<?php

$featuresitems = new WP_Query(array(
    'post_type' => 'scbleftfeatures'
));
$i = 0;

?>

<?php
while( $featuresitems->have_posts()) : $featuresitems->the_post();
    $i_is_even = ($i % 2 == 0);
    ?>

<div class="col-md-6 <?php if ($i_is_even) {echo 'left-grid'; } else { echo 'right-grid'; }; ?>">
    <div class="features-grid1">
        <div class="feature">
            <h4><?php the_title(); ?></h4>
            <?php the_content(); ?>
        </div>
        <div class="icon5">
            <?php the_post_thumbnail('features_icon_size'); ?>
        </div>
        <div class="clearfix"></div>
    </div>
</div>

<?php
$i ++;
endwhile;
?>

If you're curious about the % operator I suggest you check out the Modulus operator on http://php.net/manual/en/language.operators.arithmetic.php

And if you actually want to alter between different divs you can put the whole divs inside the if/else blocks instead of just the classes.

Edit: Not sure why you'd want this as it seems you're using the bootstrap grid anyways.
