css - Bootstrap 边栏上图标旁边的文本对齐

Question

我正在尝试修改 dashboard从引导。我在侧边栏的文本前添加了图标，类似于 this .我确实检查了后者，但它没有一些特殊的 CSS 代码来使文本具有统一的间距和对齐方式。

这是我的代码:

<ul class="nav nav-pills flex-column">
    <li class="nav-item">
        <a class="nav-link" href="/">
            <div>
                <i id="icon-dashboard" class="fa fa-tachometer icon" aria-hidden="true"></i>
                <span class="nav-link-text">Dashboard</span> <span class="sr-only">(current)</span>
            </div>
        </a>
    </li>
    <li class="nav-item">
        <a class="nav-link" href="/books">
            <div>
                <i id="icon-book" class="fa fa-book icon" aria-hidden="true"></i>
                <span class="nav-link-text">Book</span>
            </div>
        </a>
    </li>
    <li class="nav-item">
        <a class="nav-link" href="/transactions">
            <div>
                <i id="icon-transaction" class="fa fa-handshake-o icon" aria-hidden="true"></i>
                <span class="nav-link-text">Transaction</span>
            </div>
        </a>
    </li>
    <li class="nav-item">
        <a class="nav-link" href="/reports">                                
            <div></div>
            <div>
                <i id="icon-report" class="fa fa-bar-chart icon" aria-hidden="true"></i>
                <span class="nav-link-text">Report</span>
            </div>
        </a>
    </li>
</ul>

请帮我想想办法。我不知道该怎么做。谢谢。

在提供的示例中，有问题的图标应用了固定宽度，以便在整个相应的列表项中实现统一布局；其中可能还嵌套了不同宽度的图标。

考虑通过在列表项中的图标上声明类 fa-fw 来使用固定宽度图标。

Use fa-fw to set icons at a fixed width. Great to use when different icon widths throw off alignment. Especially useful in things like nav lists & list groups.

.list-group {
    margin: 20px;
