Dear Graham,
you gave me this code some days back for my site it worked here next launcher 3d shell but the code is not working on blog

<style> /* This element defines the size the iframe will take. In this example we want to have a ratio of 25:14 */ .aspect-ratio { position: relative; width: 100%; height: 0; padding-bottom: 56%; /* The height of the item will now be 56% of the width. */ } /* Adjust the iframe so it's rendered in the outer-width and outer-height of it's parent */ .aspect-ratio iframe { position: absolute; width: 100%; height: 100%; left: 0; top: 0; } </style>

Youtube Code:

<div class="aspect-ratio"><iframe src="http://m.youtube.com/watch?v=uf5HbvbPN0o" width="550" height="275" frameborder="0" allowfullscreen="allowfullscreen"></iframe></div>

This code not worked blog on blog
1. change height to auto
2. width is too much big change to 100% bro
on chrome the video doesn't show only top is visible
