Removing black borders on a vimeo iframe embed using CSS?

Question

I am trying to find a way to hide the black strips across the top and bottom of a vimeo video. I thought there might be a way to cover them up with CSS.

I basically

Answer 1

HTML:

<div class="js-video [vimeo, widescreen]">
  [video html goes here]
</div>

CSS:

.js-video {
  height: 0;
  padding-top: 25px;
  padding-bottom: 67.5%;
  margin-bottom: 10px;
  position: relative;
  overflow: hidden;
}

.js-video.widescreen {
  padding-bottom: 57.25%;
}

.js-video.vimeo {
  padding-top: 0;
}

.js-video embed, .js-video iframe, .js-video object, .js-video video {
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  position: absolute;
}

I created a solution for this exact problem using a portion of this github post. Removing Black Bars. It doesn't change vimeo's background color but merely hides it from the viewport.

https://github.com/davatron5000/FitVids.js/issues/130

#myid {
  height: 112.6%;
} 

However, If you add a width using CSS "vw"(viewport width) it will size consistently on any monitor/device without showing the black background. I added a margin so that the iframe will stay centered in the div once the width is shorter.

#myvimeoiframeID {
  height: 112%;
  width: 80vw;
  margin: 0 15% auto;

}

In my parent container that holds the video, I added:

.embed-container {
   padding-bottom: 40.25%;
}

This seems to make sure the video shows in the div. When I removed this section the video disappears but you can still here it play. So there is something that is pretty awesome with the padding-bottom: 40.25%;

I changed the vimeo embedded iframe code to have a height="100%".

So you can add a height to the iframe or you can do it in css. In order to control the height by css, I kept the base height in the iframe at 100% and any adjustments to that base height is through the css.

For your use case, I don't think you'll be able to use just css.

Usually we add letterboxing or pillar boxing around video iframes to keep the height and width at a certain ratio for presentation. But in that case, the black borders would just be as simple as a css background.

To keep things responsive, you would set the height to something like zero (like you have) and use the padding hack to keep the aspect ratio of the video (in this case a 16:9 video; 9/16 * 100 = 56.25%). That number would be either your padding-top or padding bottom value. Since the padding is measured with percent, this scales the padding in relation to the width keeping the correct ratio no matter what width you size the video to.

In your case, this video actually has the letterboxing in the actual video which you can see from the source of the video tag within the iframe. I'm not sure why you have the padding-top:30 but that makes the black borders even bigger. You'll need to hack your situation even more though because of the built in letterboxing. I put together a jsfiddle demo here which includes a few comments but it uses JS to achieve what you're looking for.

The concept for the code is as follows:

• You want the outer container to crop off the bottom and top of the video. Assuming you wanted the video to be responsive, and be cropped, you need to always have the actual video be larger than the outer container which masks it.
• The video should be moved up in relation to how wide the video is vs the thickness of the top border
• You'll want to shrink the height of the outer container a bit to compensate for the negative top margin yet still hide the bottom portion of the video

Personally I don't like doing expensive DOM operations on resize which maybe is the reason you asked for solely css but FWIW, you have the demo.

Ideally your best option would be to get the video re-recorded without the letterboxing so all you would need is the padding hack.

I solved this problem by removing padding-top in .embed-container

padding-bottom: 56.25%; will set screen ratio to 16:9 and remove the black bar in top and bottom. padding top here will add extra black bar area back.

Answer 5

I just solved this -

The video container was built with a video-captions-container DIV which was a black transparent bar.

Cut the 1px off all edges with CSS:

.embed-container { 
    position: relative; 
    padding-bottom: 43%;        /* Aspect ratio of the video */
    height: 0; 
    overflow: hidden; 
    max-width: 100%;
} 

.embed-container iframe, 
.embed-container object, 
.embed-container embed { 
    position: absolute; 
    top: -1px; 
    left: -1px;
    width: calc(100% + 2px); 
    height: calc(100% + 2px);
}
