在Unity Webgl平台下使用默认打包设置后，在浏览器中可以看到并没有做好全屏适配

游戏窗口会显示在浏览器的正中间，并且存在大片留白

以下是试验过可行的解决方案，直接复制代码使用即可~

WebGL配置

以下都是基于Unity2020.3.37f1进行设置

更改视图大小

打开index文件

调整视图大小的代码如上，推荐将其参数改为这些。

canvas.style.width = "99.15vw";
canvas.style.height = "96vh";

详细配置代码：

      
<!DOCTYPE html>
<html lang="en-us">
  <head>
    <meta charset="utf-8">
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8">

      // Shows a temporary message banner/ribbon for a few seconds, or
      // a permanent error message on top of the canvas if type=='error'.
      // If type=='warning', a yellow highlight color is used.

      // way that non-critical warnings and error messages are presented to the

          setTimeout(function() {
            warningBanner.removeChild(div);
            updateBannerVisibility();
          }, 5000);
