Aligning the iframe within a div element

When I was trying to code an iframe that would resize with the screen, I encountered a problem where I couldn't center it. Despite attempting all the suggestions provided in THIS thread, I still couldn't get it to work. Can someone please point out if I'm overlooking something obvious or if there's simply no way to achieve this?

Here is the HTML code:

<div class="videoWrap">
    <iframe src="http://www.youtube.com/embed/playlist?list=PLn0iVeY0xhgZvWDQ1K_6EChZe_4TL5zDZ"></iframe>
</div>

And here is the corresponding CSS:

.videoWrap {
    position: relative;
    padding-bottom: 56.25%; /* 16:9 aspect ratio */
    padding-top: 25px;
    height: 0;
}
.videoWrap iframe {
    position: absolute;
    top: 0;
    left: 0;
    width: 80%;
    height: 100%;
}

Answer №1

Upon reviewing the linked question... 

.videoWrap {
  display: flex;
  align-items: center;
  justify-content: center;
}

.videoWrap iframe {
  width: 300px;
  height: 300px;
}

div, body, html {
  height: 100%;
  width: 100%;
}
<div class="videoWrap">
  <iframe src="http://www.youtube.com/embed/playlist?list=PLn0iVeY0xhgZvWDQ1K_6EChZe_4TL5zDZ"></iframe>
</div>

Answer №2

One solution is to use the margin: auto; CSS property on your div element.

Answer №3

For this demonstration, I have centered the wrapper element both horizontally and vertically using standard settings (position: absolute` is used in this case). Additionally, I have specified the width and height within this code snippet. The video itself occupies the central area of the wrapper.

html, body {
  height: 100%;
  margin: 0;
}

.videoWrap {
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
  /* 16:9 */
  width: 80vw;
  height: 45vw;
}

.videoWrap iframe {
  width: 100%;
  height: 100%;
}
<div class="videoWrap">
  <iframe src="http://www.youtube.com/embed/playlist?list=PLn0iVeY0xhgZvWDQ1K_6EChZe_4TL5zDZ"></iframe>
</div>

Answer №4

Implement the following CSS properties to center an iframe horizontally:

.videoContainer {
    position: relative;
    padding-bottom: 56.25%; /* 16:9 aspect ratio */
    padding-top: 25px;
    height: 0;
}
.videoContainer iframe {
    position: absolute;
    top: 0;
    left: 50%;
    transform: translateX(-50%);
    width: 80%;
    height: 100%;
}
