Sometimes it might be useful to get information about location and size of a specific HTML Element on the loaded web page relative to the top-left of the viewport of the current document (e.g. to highlight or capture it). The DOMElement.getBoundingClientRect() method returns the size of an element and its position relative to the viewport. It's equivalent of the Web API Element.getBoundingClientRect() JavaScript function.(有时，获取有关已加载网页上特定HTML元素相对于当前文档视口左上角的位置和大小的信息可能很有用（例如，突出显示或捕获它）。 DOMElement.getBoundingClientRect（）方法返回元素的大小及其相对于视口的位置。它等效于Web API Element.getBoundingClientRect（）JavaScript函数。)
