These are some tricks:
/* Modify the read more link on the_excerpt() */
function et_excerpt_length($length) {
return 220;
}
add_filter('excerpt_length', 'et_excerpt_length');
/* Add a link to the end of our excerpt contained in a div for styling
purposes and to break to a new line on the page.*/
function et_excerpt_more($more) {
global $post;
return '<div class="view-full-post"><a href="'. get_permalink($post->ID) .
'" class="view-full-post-btn">View Full Post</a></div>;';
}
add_filter('excerpt_more', 'et_excerpt_more');
Thank you
