Question

Im sure this is super simple, all I am trying to do is center the image on the page using this.

            echo get_the_post_thumbnail( $post_id );

Any help would be much appreciated! Thanks in advance

Answer 1

echo get_the_post_thumbnail( $post_id, 'post-thumbnail', array( 'class' => 'center-img' ) );

And in your style.css create a class center-img:

.center-img {
    display: block;
    margin-left: auto;
    margin-right: auto;
}
