【问题描述】：
我正在学习前端开发。
我想在容器中间对齐矩阵和右侧列。我该怎么做？
我创建了以下内容（它是在 react 中制作的，但这是原始 html）：
我想有一种方法可以使用 HTML 和 CSS 来做到这一点，但我不知道如何去做。我尝试将事物居中，但似乎不起作用。
<html lang="en">
<head>
<meta charset="utf-8" />
<link rel="icon" href="/favicon.ico" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
<meta name="theme-color" content="#000000" />
<meta
name="description"
content="Web site created using create-react-app"
/>
<link rel="apple-touch-icon" href="/logo192.png" />
<!--
manifest.json provides metadata used when your web app is installed on a
user's mobile device or desktop. See https://developers.google.com/web/fundamentals/web-app-manifest/
-->
<link rel="manifest" href="/manifest.json" />
<!--
Notice the use of in the tags above.
It will be replaced with the URL of the `public` folder during the build.
Only files inside the `public` folder can be referenced from the HTML.
Unlike "/favicon.ico" or "favicon.ico", "/favicon.ico" will
work correctly both with client-side routing and a non-root public URL.
Learn how to configure a non-root public URL by running `npm run build`.

The build step will place the bundled scripts into the <body> tag.
To begin the development, run `npm start` or `yarn start`.
To create a production bundle, use `npm run build` or `yarn build`.
