新开发人员在为他们的项目实施或添加引导程序时通常会遇到问题。问题主要发生在在整个项目中（即在所有必需的文件上）实施引导程序，而没有在项目的每个页面上添加样式表和脚本。

不使用 Bootstrap 的示例：
<html>
<head>
<style>
.green {
color: green;
}
.yellow {
color: yellow;
}
.red {
color: red;
}
.blue {
color: blue;
}
.grey {
color: grey;
}
style>head>
<body>
<h1>Geeksforgeeksh1>

<p class="yellow">This text is in yellow colorp>
<p class="red">This text is in red colorp>
