替换HTML字符串

Question

当前，我正在使用WebView的项目中工作。该项目位于 Swift 4中。我正在从Web服务获取HTML字符串。 HTML字符串包含文本和图像。所以我想更改文本的字体大小，背景颜色以及从整个html字符串更改图像大小，假设字体大小达到10倍，那么我想更改所有字体。我正在共享HTML字符串及其输出。

在这里您可以看到背景颜色和字体大小有所不同。某个地方是粗体，某个地方是常规字体，而且图像和文字之间还有很多空间

Answer 1

只需将top：15.0pt更改为4.0pt，将所有top：6.0pt更改为2.0pt，然后更改背景：＃DAEEF3; HTML文件中的任何内容。

要更改图像大小，只需在img标签的末尾提供图像的高度和宽度。

Answer 2

最终得到了解决方案。无需替换字体大小或图像大小。请在HTML下面编写，并在两者之间传递HTML。将其加载到Webview中时，您的字体大小将正常显示，图像也将显示。 You can find image that i have implemented in my app.
