OK a small tip that I found really useful.
When your trying to get the excerpt of the post in WordPress site you use the following method,
<?php the_excerpt(); ?>
The problem with above is that it will include its own <p> or paragraph tags. There might be an occasion where you don’t wont those tags, like I did today. So then you use the following code,
<?php echo get_the_excerpt(); ?>
Hope this helps 🙂
