javascript - iframe Why do the scroll bars appear like this when loading a web page?

Question

Excuse me, why when an iframe loads a large page, a small scroll bar appears first, and only that much of the page is displayed, and then it takes a while to display all of it. Is there any way to directly display all of it? This is so ugly. . .

followed by iframe的大小有关，如果确定iframe的大小而非自适应内容的话，建议设定好iframe的width,height or:

html, body, iframe {
    width: 100%;
    height: 100%;
}
