Youtube Iframe

Hello,

I use boxed-template and want to embed Youtube Videos.

Here's the code

<div class="col-lg-6 center col-padding" style="background-color: #F5F5F5;">
	<div>
		<div class="heading-block nobottomborder">
			<span class="before-heading color">Easily Understandable & Customizable.</span>
			<h3>Walkthrough Videos & Demos</h3>
		</div>

		<div class="center bottommargin">
			<a href="https://www.youtube.com/watch?v=grzMyFK06Pc" data-lightbox="iframe" style="play-video position-relative">
				<img src="<?= base_url() . "assets/" ?>images/services/video.jpg" alt="Video">
				<span class="i-overlay nobg"><img src="<?= base_url() . "assets/" ?>images/icons/video-play.png" alt="Play"></span>
			</a>
		</div>
		<p class="lead nobottommargin">Democracy inspire breakthroughs, Rosa Parks; inspiration raise awareness natural resources. Governance impact; transformative donation philanthropy, respect reproductive.</p>
	</div>
</div>

I only change the URL to youtube video. But it says player.vimeo.com too long to respond. Is there any special youtube video's class? Or is there any mistakes on code? Thank you..

I fix this, thank you.
