此代碼以錯誤的方式運行，因為不要以 2:10 的比例創建具有兩列的一行，但第二列會下降。 我可以補充一點，當我填充包含自身 100% 寬度的內容第二列時 - 那么一切都很好。

您需要一個容器（ .container / .container-fluid ）來包裝行和列。

<div class="container">
    <div class="row">
        <div class="col-sm-2">
            <span class="badge badge-info badge-pill">2</span>
        </div>
        <div class="col-sm-10">
            <p>short text to write.</p>
        </div>
    </div>
</div>
