2 使用 Bootstrap 4 的列响应式布局

Question

如何在 Bootstrap 4 中创建一个具有响应性但列宽不固定的 2 列网格。 例如：我将在 LEFT 列中有一个具有一定宽度的图像，并且我希望 RIGHT 列能够弯曲到父 DIV 的剩余宽度。

<div class="tut_wrapper">
    <div class="container-fluid">
    <div class="row">
    <div class="col-xl-8 col-lg-12 col-md-12 col-sm-12">
         <div class="tut_leftbox"><img class="img-fluid" src="tutorials/anamorphic_drawing1.jpg"></div>
    </div>    
    <div class="col-xl-4 col-lg-12 col-md-12 col-sm-12">
         <div class="tut_rightbox">
              <h3>Introduction</h3>
              some text
         </div>
     </div>    
     </div>    
     </div>    
</div>

Answer 1

要使 div 用完剩余空间，您只需将 col 类添加到该 div。它会自动分配所有剩余的空间给它。在移动视图下（当左侧 div 占据整行时），div 会自动变为 100% 宽。

div {
border: 1px solid #000000;
}

<div class="container">
  <div class="row">
    <div class="col-4">
      ex: col-4
    </div>
    <div class="col">
      this will take up all the space left
    </div>
  </div>
</div>

或者，如果您想让左 div 与图像 100% 匹配，您可以对左 div 执行col-xs-auto，对右 div 执行col。

div {
border: 1px solid #000000;
}

<div class="container">
  <div class="row justify-content-md-center">
    <div class="col-xs-auto">
      Fixed width image here
    </div>
    <div class="col">
      Other content
    </div>
  </div>
</div>
