In this post, I describe how to add a YouTube featured playlist link below a video, above the title. Clicking this link takes you to the playlist so you can easily watch other videos in that playlist. Resolution 1. The first step I took was to add the video to a playlist in my channel. 2. Next, I made that YouTube playlist into a series playlist . The playlist link above the video title then started appearing for some of the videos in that playlist.  The series playlist also appears as a Featured playlist in the video description: But, unfortunately, this didn't apply to the latest videos in the playlist. Adding hashtags to the video title, playlist title or video description didn't seem to make any difference. I also did the same for another video in another playlist and the link hasn't appeared yet. So, it seems it may be something YouTube automatically does if a video is in a series playlist. If you have more information, please do comment below!

In this post, I describe how you can embed a YouTube video in HTML without using a fixed size height and width. Problem The problem with a fixed height and width is that the embedded YouTube video doesn't fit once the screen gets narrower than the fixed width (for example, on a mobile device) and you end up with the sides of the video being cut off and horizontal scrollbars: Resolution Thanks to CSS tricks for this post which has an excellent solution: 1. Create a container (e.g. a div) and put the embed video code from YouTube inside this container: < div class ="video-container">      < iframe src ="https://www.youtube.com/embed/HF7GTGaJdVg"></ iframe > </ div > 2. Specify the CSS for the container and the iFrame inside it: .video-container {     position : relative ;     padding-bottom : 56.63% ;     height : 0 ; }     ...

Over the last two months, I've been publishing YouTube videos to the CENTREL Solutions channel .  I'm also an avid watcher of YouTube videos and noticed that some videos had a snazzy end screen with clickable areas that took you to other videos or to allow you to subscribe to the channel. Knowing this was possible, I started to research how to add it to my videos.  I discovered the Annotations area in the Video Manager which allows you to add hotspots with links to videos, playlists, subscribe and more. I wasn't sure how to add the thumbnail screenshots but eventually figured out that you could embed them in the video itself then overlay the hotspots in the YouTube video manager later once it was uploaded. Add a YouTube End Screen In the last week or so, YouTube recently changed the annotations area.  It is now called "End screen & Annotations".  Also, as you can see in the screenshot above, if you go to annotations, you are now shown a warning that...

Problem You've embedded a video from YouTube into your HTML using their embed code e.g. <iframe width="560" height="315" src="https://www.youtube.com/embed/dNVpL2-8-BU" frameborder="0" allowfullscreen></iframe> You then validate your HTML and get the error: there is no attribute "allowfullscreen" Cause As stated by the w3c validation tool , one of the likely causes is that you're using a document type that does not support the "allowfullscreen" attribute for this element. The w3c validation tool tells you which document type you're using: In this case, we're using XHTML 1.0 Transitional which does not support allowfullscreen. Solution 1 HTML5 does support the allowfullscreen attribute on the iFrame element so changing the doctype to HTML5 will fix this issue.  You can try this from the w3c validation tool by changing the drop down just to the right of doctype from (dete...
