无法居中对齐我的按钮

Question

我正在制作一个作品集网站，因为我需要把它送到学校。 现在我正在尝试将我的按钮在网页上居中对齐。我已经尝试了很多， 给 li、ol 和几个类： text-align: center、margin-right/margin-left:auto。似乎没有任何效果。我现在已经被困了超过 1.5 小时，所以如果你们中的一个人能帮助我解决这个问题，那就太棒了。

提前非常感谢！

Answer 1

当您使用 Bootstrap 时，您不想覆盖框架提供的属性。相反，您需要做的就是为容器提供 text-center 类，它应该可以正常工作。

<div class="jumbotron">

    <div class="container container-fluid">
        <div class="row">
            <div class="col-md-12 text-center"> <!-- THIS LINE CHANGED -->
                <ol>
                    <li><a href="#" role="button">Contact</a></li>
                    <li><a href="#" role="button">Work</a></li>
                </ol>
            </div>
        </div>


        <div class="row">
            <div class="col-md-3-offset-3">


                <h1>Noah Wallaart</h1>
            </div>

            <div class="col-md-6">
            </div>
        </div>
    </div>
</div>

开始吧，添加这些样式

.midden ol {
    margin-top: 0;
    margin-bottom: 10px;
    display: table; 
    margin: 0 auto;
}
.midden li{
  float: none;
}

.midden ol {
    margin-top: 0;
    margin-bottom: 10px;
    display: table;
    margin: 0 auto;
}
.midden li{
  float: none;
}

Answer 3

您的一些标记已关闭，“midden”不是一个词，您所要做的就是“文本居中”行，它工作正常。祝你好运！

<div class="jumbotron">

    <div class="container container-fluid">
        <div class="row text-center">
            <div class="col-md-12">
                <ul class="list-unstyled list-inline">
                    <li><a href="#" role="button">Contact</a></li>
                    <li><a href="#" role="button">Work</a></li>
                </ul>
            </div>
        </div>


        <div class="row">
            <div class="col-md-3-offset-3">


                <h1>Noah Wallaart</h1>
            </div>

            <div class="col-md-6">
            </div>
        </div>
    </div>
</div>
