css - 如何使用 CSS 选择器在 Bootstrap 4 中定位移动网格类 col-1,2,3, ..........12？

问题描述

如何在 css 中仅选择 col-1,2,3......12，我尝试使用 .row [class*='col-'] 但它选择了所有网格类。

.container .row [class*="col-*"] {
  background: red !important;
}
<!DOCTYPE html>

<html lang="en" xmlns="http://www.w3.org/1999/xhtml">

<head>
  <meta charset="utf-8" />
  <title>Hi Amma Bootstrap 4 </title>
  <link rel="stylesheet" type="text/css" href="bootstrap.css" />
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <style>
    .container .row [class*="col-*"] {
      background: red !important;
    }
  </style>
</head>

<body>
  <div class="container">
    <div class="row m-4">
      <div class="col-12 col-sm-6 col-md-3 bg-success">
        Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.<br> Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.
      </div>
      <div class="col-12 col-sm-6 col-md-3 bg-warning">

      <div class="col-12 col-sm-6 col-md-3 bg-success mt-3">
        Sed ut perspiciatis unde omnis iste natus error sit voluptatem accusantium doloremque laudantium, totam rem aperiam, eaque ipsa quae ab illo inventore veritatis et quasi architecto beatae vitae dicta sunt explicabo.
