Basic js to help in a “readmore” scenario for a friend.

p.js

jQuery( function($) {
  $( document ).ready( function() {
  function showFullDesc(event, c) {
    event.preventDefault();
 
    // Get the clicked element section cover.
    $_ParentEL = $(this).closest( '.section_cover' );
    
    // Now trigger the necessary for the clicked item.
    $_ParentEL.find( '.short_d' ).css( 'display', 'none' );
    $_ParentEL.find( '.full_d' ).css( 'display', 'block' );
  }

  });

});
