HTML: 如何对齐左、中、右页脚短语。 Bootstrap

Question

我在将页脚文本对齐成一条直线时遇到问题。我是这里的初学者，所以如果这个问题是多余的，我深表歉意！见下文：

我需要这三条线都在一条直线上。

我的教授教授网格方法，但目前对我不起作用。有什么建议吗？

这是我的代码：

<html>
<head>
<meta charset="UTF-8">
<meta name="robots" content="noindex"> 

<style>

img {
  display: block;
  margin-left: auto;
  margin-right: auto;

}
</style>
<title>Custom Error Page</title>

</head>

<body>

    <div class="card">
        <div class="card-header" style = "background-color: #d8edd0">
            <h1><center>Page Not Found</center></h1>
            <h3><center>Something went wrong!</center></h3>
        </div>

    <div class="card-body">     
        <img src = "images/404.png" alt = "404" style="width:50%;"/> 
        <p style="text-align:center;">Perhaps you would like to visit the following pages:</p>
