推荐答案
最后，我找到了使用以下JavaScript代码解决此问题的方法.使用此代码，浏览器URL栏上的3种主题颜色会动态更改.
Finally I found a solution to this problem with the following JavaScript code. With this code, 3 theme-colors on browser's URL bar change dynamically.
var themeColorTest = new function() {
function e() {
"#87CEFA" === $themeColor.content ? $themeColor.content = "#1E90FF" : "#1E90FF" === $themeColor.content ? $themeColor.content = "#4169E1" : $themeColor.content = "#87CEFA",
setTimeout(e, 500)
}
this.init = function() {
$themeColor = document.querySelector("meta[name='theme-color']"),
e()
}
};
themeColorTest.init();<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Animation of meta name theme-color</title>
<meta name="theme-color" content="#87CEFA" />
</head>
<body>
