How can I align YouTube embedded video in the center in bootstrap - css

Question

I am trying to align YouTube embedded video in the center of the page in my bootstrap page. The size of the video is always the same.
My html looks really simple:
<div class="video">
<iframe width="560" height="315" src="https://www.youtube.com/embed/ig3qHRVZRvM" frameborder="0" allowfullscreen=""></iframe>
</div>
I tried different solutions from stackoverflow (which addressed just centering a div, not a video) and the best I was able to came up with was this fiddle.
I already tried solution1, solution2, solution3 but with no result. Another partially successful solution was to use:
width: 50%;
margin: 0 auto;
It worked nicely on desktop, but failed on iPad or a phone (the video went partially outside of a screen). How is it possible to center the video properly in desktop/tablet/phone?

Answer 1

An important thing to note / "Bootstrap" is just a bunch of CSS rules
a fiddle
HTML
<div class="your-centered-div">
<img src="http://placehold.it/1120x630&text=Pretend Video 560x315" alt="" />
</div>
CSS
/* key stuff */
.your-centered-div {
width: 560px; /* you have to have a size or this method doesn't work */
height: 315px; /* think about making these max-width instead - might give you some more responsiveness */
position: absolute; /* positions out of the flow, but according to the nearest parent */
top: 0; right: 0; /* confuse it i guess */
bottom: 0; left: 0;
margin: auto; /* make em equal */
}
Fully working jsFiddle is here.
EDIT
I mostly use this these days:
straight CSS
.centered-thing {
position: absolute;
margin: auto;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}
if your use stylus/mixins ( you should... it's the best )
center-center()
absolute()
margin auto
top 50%
left 50%
transform translate(-50%,-50%)
This way... you don't need to know the size of the element - and the translate is based of it's size - So, -50% of itself. Neat.

Youtube uses iframe.
You can simply set it to:
iframe {
display: block;
margin: 0 auto;
}

Answer 3

<iframe style="display: block; margin: auto;" width="560" height="315" src="https://www.youtube.com/embed/ig3qHRVZRvM" frameborder="0" allowfullscreen></iframe>

Answer 4

You dont have to put <iframe> in a parent div at all. You can target exactly youtube iframe with CSS/3:
iframe[src*="//youtube.com/"], iframe[src*="//www.youtube.com/"] {
display: block;
margin: 0 auto;
}

I set the max width for my video to be 100%. On phones the video automatically fits the width of the screen. Since the embedded video is only 560px wide, I just added a 10% left-margin to the iframe, and put a "0" back in for the margin for the mobile CSS (to allow the full width view). I did't want to bother putting a div around every video...
Desktop CSS:
iframe {
margin-left: 10%;
}
Mobile CSS:
iframe {
margin-left: 0;
}
Worked perfect for my blog (Botanical Amy).

Using Bootstrap's built in .center-block class, which sets margin left and right to auto:
<iframe class="center-block" width="560" height="315" src="https://www.youtube.com/embed/ig3qHRVZRvM" frameborder="0" allowfullscreen=""></iframe>
Or using the built in .text-center class, which sets text-align: center:
<div class="text-center">
<iframe width="560" height="315" src="https://www.youtube.com/embed/ig3qHRVZRvM" frameborder="0" allowfullscreen=""></iframe>
</div>

<div>
<iframe id="myFrame" src="https://player.vimeo.com/video/12345678?autoplay=1" width="640" height="360" frameborder="0" allowfullscreen> .
</iframe>
</div>
<script>
function myFunction() {
var wscreen = window.innerWidth;
var hscreen = window.innerHeight;
document.getElementById("myFrame").width = wscreen ;
document.getElementById("myFrame").height = hscreen ;
}
myFunction();
window.addEventListener('resize', function(){ myFunction(); });
</script>
this works on Vimeo adding an id myFrame to the iframe

make iframe with align="middle" and put it in paragraph with style="text-aling:center":

<iframe width="420" height="315" align="middle" src="https://www.youtube.com/embed/YOURVIDEO">
</iframe>
</p>

For a fully responsive IFramed YouTube video, try this:
<div class="blogwidevideo">
<iframe width="854" height="480" style="margin: auto;" src="https://www.youtube-nocookie.com/embed/h5ag-3nnenc" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>
</div>
.blogwidevideo {
overflow:hidden;
padding-bottom:56.25%;
position:relative;
height:0;
}
.blogwidevideo iframe {
left:10%; //centers for the 80% width - not needed if width is 100%
top:0;
height:80%; //change to 100% if going full width
width:80%;
position:absolute;
}

Answer 10

<center><div class="video">
<iframe width="560" height="315" src="https://www.youtube.com/embed/ig3qHRVZRvM" frameborder="0" allowfullscreen=""></iframe>
</div></center>
It seems to work, is this all you were asking for? I guess you could go about taking longer more involved routes, but this seemed simple enough.

The easiest way is by adding tag, before , open the tag and then close it after closing . As said by others tag is not supported by HTML5, and even your ide would show an error. I'm using VS Code and yes it shows an error, but if you check your website the video would be in the center. Youtube still understands the tag :)
