Ensuring an adjustable iframe with maximum width and height

Question

Ensuring an adjustable iframe with maximum width and height

In order to ensure that both images and iframes within a fixed height container are responsive and do not overflow vertically or horizontally, you can apply the following CSS:

img {
    max-width: 100%;
    max-height: 100%;
}

This CSS rule will prevent portrait images from overflowing vertically and landscape images from overflowing horizontally.

For iframes, one common technique is using the "padding-ratio" method, where the padding of the wrapper element is set to the aspect ratio of the iframe (e.g. 56.25% for a 16:9 video):

.iframe-wrapper {
    position: relative;
    height: 0;
    padding-top: 56.25%;
    overflow: hidden;
}

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

However, while this approach allows the iframe to scale with the width of the viewport, it does not adjust properly when the height of the viewport changes. The goal is to have the iframe behave similarly to how the images respond to different screen sizes.

Answer №1

When it comes to embedding Vimeo videos on a responsive website, I have found a solution that works perfectly across various browsers:

@media screen and (max-width: 750px) {
    iframe {
        max-width: 100% !important;
        width: auto !important;
        height: auto !important;
    }
}

One of the great things about this method is that it eliminates the need for image placeholders, making the process much simpler.

.video-wrapper {
    position:relative;
    padding-bottom:56.25%;
    padding-top:30px;
    height:0;
    overflow:hidden;
}

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

If you're looking for a solution, I have one that may work for you. However, you may need to compromise on the "padding ratio" technique as it might not be necessary ;)

Here is an example of HTML code that you can use:

<div class="embedded-video">
      <img class="ratio-img" src="http://placehold.it/16x9" alt="16:9 Image" />
      <iframe src="//www.youtube.com/embed/I_dN9IpmOZU" frameborder="0" allowfullscreen align="center"></iframe>
    </div>

And here is the corresponding CSS code:

.embedded-video {
    position: relative
}

.embedded-video .ratio-img {
    display: block;
    width: 100% !important;
    height: auto !important;
}

.embedded-video IFRAME {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
}

Is it possible to limit the height to a maximum height while preserving the aspect ratio? This clever technique achieves just that, and here's how you can implement it. The code I am about to share is not mine, but it has worked effectively for me:

https://codepen.io/shshaw/pen/uzlfh

Below is the code (with slight modifications) for reference: My key adjustment involves using vh units instead of a percentage.

/* Adapted from https://codepen.io/shshaw/pen/uzlfh - thanks Shaw! */

.responsive-embed {
  height: 45vh; /* Specify height */
  display: inline-block; /* Must be inline-block */
  position: relative; /* Keep the child element contained */
  
  /* min/max-width will break the aspect ratio, but otherwise work as expected */
  /*
  min-height: 200px;
  max-height: 400px;
  */
}

.responsive-embed .ratio {
  height: 100%; /* Our ratio canvas is expanded to match the specified height above. */
  width: auto; /* Allows width to adjust based on height, maintaining aspect ratio */
  visibility: hidden; /* Prevent non-transparent image or alt text from appearing */
  text-align: left;
}

.responsive-embed iframe {
  /* Make child block same size as parent */
  position: absolute !important;
  top: 0 !important; left: 0 !important;
  width: 100% !important;
  height: 100% !important;
}

<div class="responsive-embed">
