内嵌块CSS

Question

我得到的问题，在我的CSS代码....

的问题是....

为什么“图标朋友”和“图标隐私”不想被对齐文字

的Home.html

<link rel="stylesheet" href="//cdn.materialdesignicons.com/1.9.32/css/materialdesignicons.min.css"> 

<div class="privacy-select"> 
    <span class="display-ib"> 
    <span class="mdi mdi-earth"></span> 
    <p>World</p> 
    </span> 

    <ul class="my-dropdown"> 
    <li> 
     <span class="mdi mdi-account"></span> 
     <p>Friend</p> 
    </li> 
    <li> 
     <span class="mdi mdi-lock"></span> 
     <p>Privacy</p> 
    </li> 
    </ul> 

</div> 

Home.css

.privacy-select { 
    position: relative; 
    display: inline-block 
} 

span { 
    display: inline-block; 
} 

p { 
    margin: 0; 
    display: inline-block; 
} 

ul { 
    dispaly: inline-block; 
    margin: 0; 
    padding: 0; 
    list-style: none; 
} 

.my-dropdown { 
    position: absolute; 
    top: 100%; 
    right: 0; 
    margin-top: 1em; 
}

Answer 1

那是因为你们已经做出了privacy-select DIV内嵌块 - 这意味着它的宽度是一样宽，最宽的元素中 - 在这种情况下是display-ib跨度为您所做的UL绝对位置（移动出来的流动）

这意味着，因为这是不够宽为UL项目，该项目的UL将包裹除非你告诉他们不要：

.privacy-select { 
 
    position: relative; 
 
    display: inline-block; 
 
} 
 

 
span { 
 
    vertical-align: middle; 
 
} 
 

 
p { 
 
    margin: 0; 
 
    display: inline-block; 
 
} 
 

 
ul{ 
 
    margin: 0; 
 
    padding: 0; 
 
    list-style: none; 
 
} 
 

 
.my-dropdown { 
 
    position:absolute; /* does this need to be absolutely positioned - removing this is another way fix your issue */ 
 
    top:100%; 
 
    right: 0; 
 
    margin-top: 1em; 
 
    white-space:nowrap; /* add this, or alternately give this a min-width, or you could make privacy-select a block element */ 
 
}

<link rel="stylesheet" href="//cdn.materialdesignicons.com/1.9.32/css/materialdesignicons.min.css"> 
 
<div class="privacy-select"> 
 
    <span class="display-ib"> 
 
    <span class="mdi mdi-earth"></span> 
 
    <p>World</p> 
 
    </span> 
 

 
    <ul class="my-dropdown"> 
 
    <li> 
 
     <span class="mdi mdi-account"></span> 
 
     <p>Friend</p> 
 
    </li> 
 
    <li> 
 
     <span class="mdi mdi-lock"></span> 
 
     <p>Privacy</p> 
 
    </li> 
 
    </ul> 
 
</div>

删除position:absolute从.my-dropdown类

.privacy-select { 
 
    position: relative; 
 
    display: inline-block 
 
} 
 

 
span { 
 
    display: inline-block; 
 
} 
 

 
p { 
 
    margin: 0; 
 
    display: inline-block; 
 
} 
 

 
ul { 
 
    dispaly: inline-block; 
 
    margin: 0; 
 
    padding: 0; 
 
    list-style: none; 
 
} 
 

 
.my-dropdown { 
 
    top: 100%; 
 
    right: 0; 
 
    margin-top: 1em; 
 
}

<link rel="stylesheet" href="//cdn.materialdesignicons.com/1.9.32/css/materialdesignicons.min.css"> 
 

 
<div class="privacy-select"> 
 
    <span class="display-ib"> 
 
    <span class="mdi mdi-earth"></span> 
 
    <p>World</p> 
 
    </span> 
 
    
 
    <ul class="my-dropdown"> 
 
    <li> 
 
     <span class="mdi mdi-account"></span> 
 
     <p>Friend</p> 
 
    </li> 
 
    <li> 
 
     <span class="mdi mdi-lock"></span> 
 
     <p>Privacy</p> 
 
    </li> 
 
    </ul> 
 
    
 
</div>

改变位置从absolute到relative。所以，你的图标将是相对于DIV

.my-dropdown { 
    position: relative; 
    top: 100%; 
    right: 0; 
    margin-top: 1em; 
} 

Answer 4

你.my-dropdown容器太窄 - 设置一个宽度，并allign它left: 0代替right: 0。

此外，您在'display'有一个错字的ul

.privacy-select { 
    position: relative; 
    display: inline-block 
} 

span { 
    display: inline-block; 
} 

p { 
    margin: 0; 
    display: inline-block; 
} 

ul { 
    display: inline-block; 
    margin: 0; 
    padding: 0; 
    list-style: none; 
} 

.my-dropdown { 
    position: absolute; 
    width: 90px; 
    top: 100%; 
    left: 0; 
    margin-top: 1em; 
}
