CSS margins and responsive videos

I'm been brushing on my CSS so that I can make changes to my website. I've learned it in the past but it's been awhile. So I've been perusing classes here to get back up to speed.

I have added coding to make youtube videos that I add into my blog posts responsive. And that's working great. But there's almost no margin underneath the video and nothing that I do changes that...except wrapping everything inside a p tag. That works and gives me the look I want but that doesn't seem to be the correct way to do it.

Here is my first attempt for the HTML code to embed the video:

<div class="youtubevid"><iframe width="570" height="" src="https://www.youtube.com/embed/I1BGchuEL6M?rel=0" frameborder="0" allowfullscreen=""></iframe></div>

with the associated CSS:

.youtubevid { position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden; margin-bottom: 25px; }

.youtubevid iframe { position: absolute; top: 0; left: 0; width: 100%; height: 100%; }

The result of this coding is a responsive video, with a nice size top margin but almost no bottom margin.

==========

My second attempt:

<div class="vidspace"><div class="youtubevid"><iframe width="570" height="" src="https://www.youtube.com/embed/I1BGchuEL6M?rel=0" frameborder="0" allowfullscreen=""></iframe></div></div>

with the CSS:

.youtubevid { position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden; }

.youtubevid iframe { position: absolute; top: 0; left: 0; width: 100%; height: 100%; }

.vidspace { margin-bottom: 25px; }

The result of this coding is the same as the first attempt.

==========

My third attempt:

<p><div class="youtubevid"><iframe width="570" height="" src="https://www.youtube.com/embed/I1BGchuEL6M?rel=0" frameborder="0" allowfullscreen=""></iframe></div></p>

with the CSS:

.youtubevid { position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden; }

.youtubevid iframe { position: absolute; top: 0; left: 0; width: 100%; height: 100%; }

The result of this coding is exactly what I want - nice size margins on both the top and bottom. But using a p tag seems the wrong way to do it.

Can anyone tell me what I'm doing wrong?

Hello! Thank you so much for your response!

I found the problem...and it's the browser!

I looked at the page on other browsers and I could see the margins that I wanted appeared on the page there. Then, using the inspect tool on the page in the Opera browser, I could see that the CSS that was being applied to the video didn't include the line for margins.

So it seems that Opera wasn't using the most recent version of my CSS file.

I cleared my Opera browser cache and restarted it and now I can see the margins appear as I want.

Again, thank you so much for your response!

The very first example should do the trick, don't you see the 25px bottom margin?

Perhaps this code is being combined with some other CSS that is overriding the margin?
