Window: sizeToContent() method

Non-standard: This feature is not standardized. We do not recommend using non-standard features in production, as they have limited browser support, and may change or be removed. However, they can be a suitable alternative in specific cases where no standard option exists.

The Window.sizeToContent() method sizes the window according to its content. In order for it to work, the DOM content should be loaded when this function is called—for example, once the DOMContentLoaded event has been thrown.

Since Firefox 20, the minimal size of the window is clamped to prevent the window from being too small for the user to interact with.

None.
