使引導網格居中而不影響容器中項目的對稱性

Question

我有 4 個 2 x 2 的圖形，它們的布局很好，但它們被推到了屏幕的左側。 當我嘗試添加一列時（也許這就是我出錯的地方），一切都變得混亂了。 我想要兩行左側的寬度為 2 的列，然后是包含 4 個圖表的 2 x 2 網格。

 <div class="container-fluid">

     </div>
      <div class="row">
        <div class="col-sm-4">
          <img src="fig1.png" alt="Bootcamp" width="450" height="350">
        </div>
        <div class="col-sm-4">
          <img src="fig2.png" alt="Bootcamp" width="450" height="350">
        </div>
      </div>
    </div> 
    <div>
      <div class="container-fluid">
        <div class="row">
          <div class="col-sm-4">
            <img src="fig3.png" alt="Bootcamp" width="450" height="350">
          </div>
          <div class="col-sm-4">
            <img src="fig4.png" alt="Bootcamp" width="450" height="350">
          </div>
        </div>
      </div> 

Answer 1

我已根據您的要求修改了代碼。 此外，為了制作您的內容中心，我將 class justify-content-center添加到 class row div。

 <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.0/css/bootstrap.min.css" integrity="sha384-9aIt2nRpC12Uk9gS9baDl411NQApFmC26EwAOH8WgZl5MYYxFfc+NcPb1dKGj7Sk" crossorigin="anonymous"> <script src="https://code.jquery.com/jquery-3.5.1.slim.min.js" integrity="sha384-DfXdz2htPH0lsSSs5nCTpuj/zy4C+OGpamoFVy38MVBnE+IbbVYUew+OrCXaRkfj" crossorigin="anonymous"></script> <script src="https://cdn.jsdelivr.net/npm/popper.js@1.16.0/dist/umd/popper.min.js" integrity="sha384-Q6E9RHvbIyZFJoft+2mJbHaEWldlvI9IOYy5n3zV9zzTtmI3UksdQRVvoxMfooAo" crossorigin="anonymous"></script> <script src="https://stackpath.bootstrapcdn.com/bootstrap/4.5.0/js/bootstrap.min.js" integrity="sha384-OgVRvuATP1z7JjHLkuOU7Xw704+h835Lr+6QL9UvYjZE3Ipu6Tp75j7Bh/kR0JKI" crossorigin="anonymous"></script> <div class="container-fluid"> <div class="row justify-content-center"> <div class="col-sm-2"> TEXT 1 </div> <div class="col-sm-4"> <img src="fig1.png" alt="Bootcamp" width="450" height="350"> </div> <div class="col-sm-4"> <img src="fig2.png" alt="Bootcamp" width="450" height="350"> </div> </div> <div class="row justify-content-center"> <div class="col-sm-2"> TEXT 2 </div> <div class="col-sm-4"> <img src="fig3.png" alt="Bootcamp" width="450" height="350"> </div> <div class="col-sm-4"> <img src="fig4.png" alt="Bootcamp" width="450" height="350"> </div> </div> </div>

Answer 2

如果我理解正確，其中任何一個都應該有效：

選項1：

<div class="container-fluid">
    <div class="row">
        <div class="col-sm-2 bg-dark text-light">
            <div>
                <p>Text 1</p>
            </div>
            <div>
                <p>Text 2</p>
            </div>
        </div>
        <div class="col-sm-10">
            <!-- Add another row inside the remaining space, then add the 2 columns for graphs -->
            <div class="row">
                <div class="col-sm-6">
                    <img src="img1.png" class="img-fluid" alt="Bootcamp">
                </div>
                <div class="col-sm-6">
                    <img src="img2.png" class="img-fluid" alt="Bootcamp">
                </div>
                <div class="col-sm-6">
                    <img src="img3.png" class="img-fluid" alt="Bootcamp">
                </div>
                <div class="col-sm-6">
                    <img src="img4.png" class="img-fluid" alt="Bootcamp">
                </div>
            </div>
        </div>
    </div>
</div>
