How can I create a responsive iframe in a Webflow column that scales proportionally with different screen widths?

TL;DR

Add an Embed element in Webflow and paste the iframe code inside.
Wrap the iframe in a div with a class like responsive-iframe-wrapper.
Set the div’s position to relative and padding-top: 56.25% (for 16:9 aspect ratio).
Set the iframe’s position to absolute, covering the parent div.
Add the following custom CSS in Page Settings > Custom Code:
```css
.responsive-iframe-wrapper {
position: relative;
width: 100%;
padding-top: 56.25%;
}
.responsive-iframe-wrapper iframe {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
}
```
This ensures the iframe maintains its aspect ratio and scales responsively.

To create a responsive iframe in a Webflow column that scales proportionally, you need to use CSS techniques to maintain the aspect ratio.

Modify the iframe with a container div that maintains the aspect ratio:

Wrap the iframe in a div with a class like responsive-iframe-wrapper.
Set the div’s position to relative and define an aspect ratio using padding-top.
Example: 56.25% (16:9 aspect ratio).
Set the iframe’s position to absolute, making it cover the parent div.

Paste this inside the Embed element:

<div class="responsive-iframe-wrapper">  <iframe src="YOUR_IFRAME_URL" frameborder="0" allowfullscreen></iframe></div>
