我正在使用一个 html 文件，其中在 html 中嵌入了一个游戏，但是，我只想显示游戏，并且似乎在右侧和底部的 html 容器中的游戏外部出现了一些空间。如何让我的游戏占据整个 html 容器？这是它的代码：
<!doctype html>
<html>
<meta name="viewport" content="width=device-width,height=device-height,user-scalable=no,target-densitydpi=device-dpi,initial-scale=1.0, minimum-scale=1.0, maximum-scale=1.0" />

<link rel="stylesheet" href="css/main.css">

<body>
