Videos go outside the div

I am using hip hop theme, and my YouTube videos go outside the container. How can I fix it? Which file in the wordpress folder do I need to edit, and what should I edit so that adding videos also stretches the container down?
Thank you!!

Hi!

You may solve this by editing the style.css file of the theme, find the code:

.articles .post-body  {
	border:none;
	padding:0 10px 70px;
	margin:0 10px;
	overflow:visible;
	
}

and replace it with:

.articles .post-body  {
	border:none;
	padding:0 10px 70px;
	margin:0 10px;
	overflow:hidden;
}
