HTMLFencedFrameElement: height property

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The height property of the HTMLFencedFrameElement gets and sets the value of the corresponding <fencedframe> height attribute, which specifies the height of the element.

The size of the embedded content may be set by internal contentWidth and contentHeight properties of the <fencedframe>'s config object. In such cases, changing the width or height of the <fencedframe> will change the size of the embedded container on the page, but the document inside the container will be visually scaled to fit. The reported width and height of the embedded document (i.e. Window.innerWidth and Window.innerHeight) will be unchanged.


A string representing the height of the element in CSS pixels. The default value is 150.


const frame = document.createElement("fencedframe");
frame.height = "320";
