文本对齐规则未按预期工作

Question

.shrink-side-bar{
    width: 5%;
    height: 100%;
    background-color: aqua;
}
    
.shrink-icon{
    width:38px;
    height: 50px;
    margin-left: -152%;
    margin-top: 54%;
}
    
li img {
    text-align: center;
}

.shrink-menu{
    list-style: none;    
}

li i {
    text-align: center;
}

<body>
    <div id="shrink-side-bar" class="shrink-side-bar">
        <ul class="shrink-menu">
            <li><img class="shrink-icon" src="img/logo%20tkb.png"></li>
            <li><i class="fa fa-sun-o"></i></li>
            <li><i class="fa fa-envelope-o"></i></li>
            <li><i class="fa fa-chevron-right"></i></li>
            <li><i class="fa fa-file-code-o"></i></li>
        </ul>
    </div>
</body>

在上面的代码中，我试图对齐水色条中间的图标，但它没有按预期工作。任何人都可以帮我修复这个错误吗？ text-align 规则在 li a 选择器中。

Answer 1

您只需要取消 "shrink-menu" 的填充，然后像这样在列表项上设置文本对齐...

.shrink-side-bar{
        width: 5%;
        height: 100%;
        background-color: aqua;
       
    }
    .shrink-icon{
        width:38px;
        height: 50px;
        margin-left: -152%;
        margin-top: 54%;
        
        
    }
    li img{
        text-align: center;
    }
    .shrink-menu{
        list-style: none;
        padding: 0;    
    }
li {
    text-align: center;
}

在

li i{
position:relative;
  left:-30px;
}

.shrink-side-bar{
        width: 5%;
        height: 100%;
        background-color: aqua;
       
    }
    .shrink-icon{
        width:38px;
        height: 50px;
        margin-left: -152%;
        margin-top: 54%;
        
        
    }
    li img{
        text-align: center;
    }
    .shrink-menu{
        list-style: none;    
    }
li i{
    text-align: center;
  position:relative;
  left:-30px;
  top:-20px;
}

Answer 4

我不知道你到底想要什么，但我认为通过改变它可以解决你的问题

.shrink-icon {
        padding: 12px;
        width: 100%;
        height: 10%;
        margin-left: -13px;
        margin-top: 54%;
    }
