图像不适合WKWebView

Question

试图显示以下请求。

class ViewController: UIViewController, WKNavigationDelegate {

@IBOutlet weak var webView: WKWebView!
override func viewDidLoad() {
    super.viewDidLoad()
    webView.navigationDelegate = self
    let htmlString = "<p><a href=\"https://miro.medium.com/max/3336/1*iGyyen2re8-dgQJlL65axw.png\"><img src=\"https://miro.medium.com/max/3336/1*iGyyen2re8-dgQJlL65axw.png\" class=\"alignnone size-full\"></a></p>\n<p></p>\n<p>Vijay Chandrasekhar: \"Robin Uthappa, Faiz Gaza's have already users kookaburra bats before in an international game\"<br><br>Sivan dune just got his t29I cap from Ravi Shastri. He becomes the 82nd cricketer to represent Indian in the format. </p>"
    var headerString = "<header><meta name='viewport' content='width=device-width, initial-scale=0.65, maximum-scale=0.65, minimum-scale=0.65'></header>"
    headerString.append(htmlString)
    webView.loadHTMLString(headerString, baseURL: nil)

}

不幸的是，WKWebview中的图像尺寸非常大。因此，发生了水平滚动。但是，我不希望这种行为。

期望图像大小应与WKWebView相同。

您可以考虑以下两种解决方案之一：

1. 只需使用CSS width: 100%拉伸它（高度将自动计算）
2. 将其用作整个页面的背景图像，并使用CSS background-size: 100%或background-size: cover对其进行拉伸>

实际上看到此：Stretch and scale a CSS image in the background - with CSS only
