How To Embed A Youtube Playlist On Your Blogger Blog?

In this post we will see how to create a YouTube video gallery using jQuery. It is an elegant gallery in which we can add 5 videos and for its dimensions, we could put it below the blog header. Actually you can put it anywhere, but it is recommended in that area considering that 765px is the width of the gallery.

youtube to blogger
To add this video slider to your blog go to Template > Edit HTML and before the </head> tag, add these scripts:

<script>

Then add the styles before ]]></b:skin>


 /* Video Gallery for Blogger
----------------------------------------------- */
#videoslider {
background:#000; /* Background color */
clear:both;
margin:0 auto;
padding:5px;
width:765px;
border-radius: 5px;
-moz-background-clip: padding;
-webkit-background-clip: padding-box;

#videoslider-tabs {float:right;width:300px;margin:0;}

text-decoration:none;
}

#videoslider-tabs li.actVid .vidDesc {color:#fff;}
.ui-widget-content{float:right;}
.tabs-outer {background-image: none !important;}
#videoslider-tabs li a:hover {background: none !important;}
Now in a HTML/Javascript gadget paste the structure of the slider, this is the one you should put under the header:
 <script>
var video = [];
video[1] = '<iframe width="460" height="345" src="http://www.youtube.com/embed/video_ID_1" frameborder="0" allowfullscreen></iframe>';
video[2] = '<iframe width="460" height="345" src="http://www.youtube.com/embed/video_ID_2" frameborder="0" allowfullscreen></iframe>';
video[3] = '<iframe width="460" height="345" src="http://www.youtube.com/embed/video_ID_3" frameborder="0" allowfullscreen></iframe>';
video[4] = '<iframe width="460" height="345" src="http://www.youtube.com/embed/video_ID_4" frameborder="0" allowfullscreen></iframe>';
video[5] = '<iframe width="460" height="345" src="http://www.youtube.com/embed/video_ID_5" frameborder="0" allowfullscreen></iframe>';
</script>
<div id="videoslider">
<div id="videoslider-content"></div>
<ul id="videoslider-tabs">
<li><a href="#vid1"><img src="//i2.ytimg.com/vi/video_ID_1/default.jpg" class="thumb-vid" /><span class="vidTit">Video Name</span><span class="vidDesc">Video Description</span></a></li>

<li><a href="#vid2"><img src="//i2.ytimg.com/vi/video_ID_2/default.jpg" class="thumb-vid" /><span class="vidTit">Video Name</span><span class="vidDesc">Video Description</span></a></li>

<li><a href="#vid3"><img src="//i2.ytimg.com/vi/video_ID_3/default.jpg" class="thumb-vid" /><span class="vidTit">Video Name</span><span class="vidDesc">Video Description</span></a></li>

<li><a href="#vid4"><img src="//i2.ytimg.com/vi/video_ID_4/default.jpg" class="thumb-vid" /><span class="vidTit">Video Name</span><span class="vidDesc">Video Description</span></a></li>

<li><a href="#vid5"><img src="//i2.ytimg.com/vi/video_ID_5/default.jpg" class="thumb-vid" /><span class="vidTit">Video Name</span><span class="vidDesc">Video Description</span></a></li>

</ul>
</div>

Add the IDs of the videos, their names and their description and that's it. The description should be brief so you wont have space problems.
If you do not know how to get the ID of a video, then open the video on YouTube and look at the address bar... the last characters are the ID you need.


Note that the ID of each video should be added two times, one is for displaying the video and one for the tabs thumbnail.

As this gallery works with jQuery we should make sure to not repeat the version of the script if we already have jQuery.
