Making an iframe responsive

Question

I was reading this stackoverflow post titled "Can you make an iFrame responsive?", and one of the comments/answers led me to this jfiddle.

But when I tried to implement the HTML and CSS to fit my needs, I didn't have the same results/success. I created my own JS fiddle so I could show you how it doesn't work the same for me. I'm sure it has something to do with the type of iFrame I'm using (e.g., the product images might need to be responsive too or something?)

My main concern is that when my blog readers visit my blog on their iPhone, I don't want everything to be at x width (100% for all my content) and then the iFrame misbehaves and is the only element wider (and hence sticks out past all the other content - if that makes sense??)

Anyway, does anyone know why it's not working? thank you.

here is the HTML & CSS of MY JSFIDDLE (if you don't want to click on the link):

<div class="wrapper">
  <div class="h_iframe">
    <!-- a transparent image is preferable -->
    <img class="ratio" src="http://www.brightontheday.com/wp-content/uploads/2013/07/placeholder300.png" />
    <iframe frameborder='0' height='465px' width='470px' scrolling='no' src='http://currentlyobsessed.me/api/v1/get_widget?wid=30&blog=Brighton+The+Day&widgetid=38585'
      frameborder="0" allowfullscreen></iframe>
  </div>
</div>

and here is the accompanying CSS:

.wrapper {
  width: 100%;
  height: 100%;
  margin: 0 auto;
  background: #ffffff;
}

.h_iframe {
  position: relative;
}

.h_iframe .ratio {
  display: block;
  width: 100%;
  height: auto;
}

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

Answer 1

DA is right. In your own fiddle, the iframe is indeed responsive. You can verify that in firebug by checking iframe box-sizing. But some elements inside that iframe is not responsive, so they "stick out" when window size is small. For example, div#products-post-wrapper's width is 8800px.

Answer 2

For Example :

<div class="intrinsic-container">
  <iframe src="//www.youtube.com/embed/KMYrIi_Mt8A" allowfullscreen></iframe>
</div>

CSS 

.intrinsic-container {
  position: relative;
  height: 0;
  overflow: hidden;
}

/* 16x9 Aspect Ratio */
.intrinsic-container-16x9 {
  padding-bottom: 56.25%;
}

/* 4x3 Aspect Ratio */
.intrinsic-container-4x3 {
  padding-bottom: 75%;
}

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

I found a solution from from Dave Rupert / Chris Coyier. However, I wanted to make the scroll available so I came up with this:

// HTML

<div class="myIframe"> 
   <iframe> </iframe> 
</div>

// CSS

.myIframe {
     position: relative;
     padding-bottom: 65.25%;
     padding-top: 30px;
     height: 0;
     overflow: auto; 
     -webkit-overflow-scrolling:touch; //<<--- THIS IS THE KEY 
     border: solid black 1px;
} 
.myIframe iframe {
     position: absolute;
     top: 0;
     left: 0;
     width: 100%;
     height: 100%;
}

Answer 4

Simple, with CSS:

iframe{
width: 100%;
max-width: 800px /*this can be anyting you wish, to show, as default size*/
}

Please, note: But it won't make the content inside it responsive!

Answer 5

Fully responsive iFrame for situations where aspect ratio is unknown and content in the iFrame is fully responsive.

None of the above solutions worked for my need, which was to create a fully responsive iFrame that had fully responsive dynamic content inside of it. Maintaining any kind of aspect ratio was not an option.

1. Get height of your navigation bar and any content ABOVE or BELOW the iFrame. In my case I only needed to subtract the top navbar and I wanted the iFrame to fill all the way down to the bottom of the screen.

Code:

function getWindowHeight() {
        console.log('Get Window Height Called')
        var currentWindowHeight = $(window).height()

        var iFrame = document.getElementById("myframe")
        var frameHeight = currentWindowHeight - 95

        iFrame.height = frameHeight; 

    }
//Timeout to prevent function from repeatedly firing
    var doit;
    window.onresize = function(){
      clearTimeout(doit);
      doit = setTimeout(resizedw, 100);
    };

I also created a timeout so that on resize the function wouldn't get called a million times.

I present to you The Incredible Singing Cat solution =)

.wrapper {
    position: relative;
    padding-bottom: 56.25%; /* 16:9 */
    padding-top: 25px;
    height: 0;
}
.wrapper iframe {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
}

As you move the window bar, you'll see iframe to responsively resize

Alternatively, you may also use the intrinsic ratio technique - This is just an alternate option of the same solution above (tomato, tomato)

.iframe-container {
  overflow: hidden;
  padding-top: 56.25%;
  position: relative;
} 

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