How to make it responsive? (Solved)

Previous was closed… If this one is closed again I won’t try to help anymore.

Add CSS Style:

/* Flexible iFrame */

.Flexible-container {
    position: relative;
    padding-bottom: 56.25%;
    padding-top: 30px;
    height: 0;
    overflow: hidden;
}

.Flexible-container iframe,
.Flexible-container object,
.Flexible-container embed {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
}

Edit line 35 in gmtr-shortcode.php
Change this

// Fix
	$op.='<style type="text/css">#'. $gmr_id .' img { max-width:none; } </style>';
        $op.='<div id="' . $gmr_id . '" style="width:' . $width . 'px;height:' . $height . 'px"></div>';

Using this

// Fix
	$op.='<style type="text/css">#'. $gmr_id .' img { max-width:none; } </style>';
        $op.='<div class="Flexible-container" id="' . $gmr_id . '"></div>';
