Css 如何在 li 中换行文本

Question

我正在尝试将我的文本包装在我的幻灯片菜单中。我有 ul max-width 200px，但是当我写更长的文本时，我的文本不可见（现在我添加了 overflow: visible 来向你展示我的意思）。如何包装这个？

我的代码如下所示：

 <nav class="navbar navbar-default" role="navigation">

<div class="dropdown">
    <button class="btn btn-default dropdown-toggle" type="button" id="dropdownMenu1" data-toggle="dropdown">
        Dropdown
        <span class="caret"></span>
    </button>
    <ul class="dropdown-menu" style="max-width: 200px" role="menu" aria-labelledby="dropdownMenu1">
        <li role="presentation" class="dropdown-header">Dropdown header</li>
        <li role="presentation"><a role="menuitem" tabindex="-1" href="#">Action</a></li>
        <li role="presentation"><a role="menuitem" tabindex="-1" href="#">Another action</a></li>
        <li role="presentation" class="disabled"><a role="menuitem" tabindex="-1" href="#">Something else here</a></li>
        <li role="presentation" class="divider"></li>
        <li role="presentation" class="dropdown-header">Dropdown header</li>
        <li role="presentation"><a role="menuitem" tabindex="-1" href="#">Separated link</a></li>
    </ul>
</div>

</nav>

现在是 CSS：

 <style>

    .dropdown .dropdown-menu {
        -webkit-transition: all 0.3s;
        -moz-transition: all 0.3s;
        -ms-transition: all 0.3s;
        -o-transition: all 0.3s;
        transition: all 0.3s;

        max-height: 0;
        display: block;
        overflow: hidden; <-- here i was trying to add  word-wrap: break-word; but it doesn'twork
        opacity: 0;
    }

    .dropdown.open .dropdown-menu {
        max-height: 200px;
        opacity: 1;
    }
</style>

您可以在 --- word-wrap: break-word; li 。检查下面的更新片段..

 .dropdown-menu li, .dropdown-menu li a {
    white-space: normal;
    float: left;
    width: 100%;
    height: auto;
    word-wrap: break-word;
}

        <li role="presentation"><a role="menuitem" tabindex="-1" href="#">Separated link</a></li>
    </ul>
</div>

</nav>

试试这个：

 .dropdown-header {
  overflow-wrap: break-word;
  word-wrap: break-word;
  white-space: normal !important;
}
