Posted 2021-02-26

var maxWidth = '750'; // Max width of area to be resized
var content_area_id = ''; // ID of the element to be resized
 
var resizeTimeout = null;
 
function fixWidth() {
	var visibleArea = document.documentElement.clientWidth;
	if (visibleArea > maxWidth) {
		document.getElementById(content_area_id).style.width = maxWidth;
	} else {
		document.getElementById(content_area_id).style.width = visibleArea;
	}
}
 
function addLoadEvent(func) {
	var oldonload = window.onload;
	if (typeof window.onload != 'function') {
			window.onload = func;
		} else {
			window.onload = function() {
			if (oldonload) {
				oldonload();
			}
			func();
		}
	}
}
 
window.onresize=function(){
	if (resizeTimeout) {
		window.clearInterval(resizeTimeout);
	}
	resizeTimeout = setTimeout(fixWidth, 500);
}
 
addLoadEvent(fixWidth);
