What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

<?php

   function add_current_nav_class($classes, $item) {

      // Getting the current post details
      global $post;

      // Get post ID, if nothing found set to NULL
      $id = ( isset( $post->ID ) ? get_the_ID() : NULL );
