Constants

fitContentJs → const String
JavaScript code to determine the tightest possible dimensions (width and height) that encompass all rendered HTML elements. This computes the maximum right and bottom coordinates from the getBoundingClientRect() of all elements.
fitHeightJs → const String
JavaScript code to determine the tightest possible height that encompass all rendered HTML elements. This computes the maximum bottom coordinates from the getBoundingClientRect() of all elements.
fitWidthJs → const String
JavaScript code to determine the tightest possible width that encompass all rendered HTML elements. This computes the maximum right coordinates from the getBoundingClientRect() of all elements.
fullScrollJs → const String
JavaScript code to determine the maximum potential width and height of the HTML document by taking the largest values from scrollWidth, offsetWidth, and clientWidth properties of both document.body and document.documentElement. This is useful for capturing the full scrollable content size.
