html - 居中 Font Awesome 图标

Question

以前有人问过这个问题，但在阅读了这些线程中的每条评论后，我无法得到有效的解决方案。

我试图简单地将 Font Awesome 图标与 div 中的文本居中。文本完美居中，图标偏左。

HTML:

<div class="work-section" id="work">
    <div class="container">
        <div class="work-section-head text-center wow fadeInRight" data-wow-delay="0.4s">
            <h3>Event name placeholder</h3>         
        </div>
        <div class="work-section-grids text-center wow fadeInUp" data-wow-delay="0.4s">
            <div class="col-md-3 work-section-grid text-center">
                <i class="fa fa-users fa-5x icons"></i>
                <h4>Who</h4>
                <p>People placeholder</p>               
            </div>
            <div class="col-md-3 work-section-grid wow fadeInUp" data-wow-delay="0.6s">
                <i class="fa fa-calendar fa-5x icons"></i>
                <h4>When</h4>
                <p>Date placeholder </p>                
            </div>
            <div class="col-md-3 work-section-grid wow fadeInUp" data-wow-delay="0.8s">
                <i class="fa fa-globe fa-5x icons"></i>
                <h4>Where</h4>
                <p>Place placeholder</p>
            </div>
            <div class="col-md-3 work-section-grid wow fadeInUp" data-wow-delay="1s">
                <i class="fa fa-question-circle fa-5x icons"></i>
                <h4>What</h4>
                <p>Information placeholder </p>
            </div>
        </div>  
    </div>
</div>

    }
}

[class^="icons"], [class*=" icons"] {
    text-align:center;
    display:inline-block;
}

当我设置图标 width:7% 时，我可以让它居中，但这只是一个静态解决方案。

Answer 1

只需一个 text-align:center; 就可以了

.wow{
    border:1px solid black;
    text-align:center;
}

<link href="//maxcdn.bootstrapcdn.com/font-awesome/4.2.0/css/font-awesome.min.css" rel="stylesheet"/>
<div class="col-md-3 work-section-grid wow fadeInUp" data-wow-delay="0.6s">
                <i class="fa fa-calendar fa-5x icons"></i>
                <h4>When</h4>
                <p>Date placeholder </p>                
            </div>
