creating a 16:9 aspect ratio iframe based on browser size (percentage)
15,025
If you add a wrapper div you can get CSS to do the trick:
<div class="fluidMedia">
<iframe src="" frameborder="0"> </iframe>
</div>
<div class="fluidMedia" style="width:80%;">
<iframe src="" frameborder="0"> </iframe>
</div>
CSS:
.fluidMedia {
position: relative;
padding-bottom: 56.25%; /* proportion value to aspect ratio 16:9 (9 / 16 = 0.5625 or 56.25%) */
height: 0;
overflow: hidden;
}
.fluidMedia iframe {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
}

how can I set a iframe size (in my case - featherlight iframe playing youtube) to be a percentage of the browser windows ?
I have a browser that may be any size, and I want to set the iframe width to be 80% of browser window..
16:9 aspect ratio with fixed width mentions how to set the 16:9 height once I select a width. I don't understand how to use it.
any jsfiddle example (or codepen) will help a lot. I have tried a bunch of different ways - but the iframe does not maintain aspect ratio.

<iframe src="https://www.youtube.com/embed/YAcLViTHDOo" width="50%" class="player" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen> </iframe>
How can I set the width to be 80% of browser window and allow height to be 16:9 ratio of the 80% of the width ?

hypermails over 8 yearsdoesn't work well if I reduce the width to a small number - like 20% codepen.io/anon/pen/EVyYyq

GlabbichRulz almost 6 yearswhy did you include
padding-top: 30px;
? -
GlabbichRulz almost 6 yearsWithout removing it, i got a black bar at the top and bottom of a 16:9 player (i guess its 30px high). Removing the
padding-top: 30px;
did remove the border. As i don't see it mentioned in the source either, i will suggest an edit -
