You might have some lengthy excerpts or content in some of your posts and pages, which are taking up too much space when listing them on your website. Learn how to limit the length of these when querying WordPress, so you can display a more ‘trimmed down’ list of posts/pages.
This code will pass your excerpt/content onto the function, which cuts the string length and adds 3 dots to the end (but only if it exceeds 300 characters), before returning the newly formatted output for you to echo on screen.
This is a great technique to use on archive and category-based pages.
