wp_enqueue_style(‘colorbox.css’, ‘\wordpress\wp-content\plugins\calc_plugin\colorbox.css’);

wp_enqueue_script(‘jquery.js’);
wp_enqueue_script(‘colorbox.js’, ‘\wordpress\wp-content\plugins\calc_plugin\colorbox.js’, array(‘jquery’));

function calc_form_markup() {
$markup = <<<EOT

<script>
$(document).ready(function(){
$(“.inline”).colorbox({inline:true, width:”600″, height:”450″});
});
</script>

<div style=’display:none’>

<div id=’inline_content1′ style=’padding:10px; background:#fff;’>
<p>This is inline content 1</p>
<image src = “https://wallpaper.goodfon.com/image/240138-1360×768.jpg&#8221; width = “175” height = ” 150″>
