But either of the two methods opens a new webpage.  That seems a bit clunky.  Why not do something far more slick like a Popup?  Well, as mentioned above there are issues with that.  And also mentioned above is a better solution.  Use a lightbox.  After installing the Featherlight Lightbox, insert the below PHP code into the theme's (or child theme's) functions.php file;<syntaxhighlight lang="text">
function generate_custom_read_more_link()

global $post;
// "Gets" the ID of the current post from the POSTS Table
