Text-align属性在此代码中不能正常工作

Question

在这段代码中，类"robin"上的text-align属性不能正常工作。我想把图标放在中间。但是所有这些都打印在同一行。

     <div id="good">
            <div id="vahid">

你不需要那么多换行标签。只需使用一个段落，并将其设置为文本居中对齐。图标将落在适当的位置，你不需要一堆周围的br标签。

或者在同一行....

p.icons { text-align: center;  padding: 0 3px;}

<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.6.3/css/font-awesome.min.css" rel="stylesheet"/>
                <div id="one">
                    <div id="fizz"><img src="image1.jpg"></div>
                      <p class="icons">
                            <i class="robin fa fa-glass"></i>
                            <i class="robin fa fa-th"></i>
                            <i class="robin fa fa-th-large"></i>
                            <i class="robin fa fa-align-justify"></i>
                       </p>

在.robin类中尝试此代码…

.robin{
    color: white;
    margin-top: 25%;
    margin-left: auto;
    margin-right: auto;
    display:table;
}
