显示Flex水平居中问题

问题描述 投票：0回答：4

我在将 div 中的元素居中时遇到问题。

我使用 display flex、align-self 和 justify-self 将其居中。

我认为这样就可以了，但是当我从网络浏览器检查时，我有一个未知元素。

你可以看到右边有一个条纹元素，我不知道它来自哪里。

这是用grid制作的父元素。

您可以从这里的小提琴中看到问题

这是我的CSS

.customer_card{
    background: green;
    padding: 10px;
    margin-bottom: 20px;
    border-radius: 10px;
    display: grid;
    grid-template-columns: 20% 80%;
    gap: 0px 10px;
    justify-content: center;
    justify-items: stretch;
    align-items: center;
}

.customer_card_logo {
    display: flex;
    position: relative;
    justify-self: center;
    text-align: center;
    background: grey;
    border-radius: 50%;
    width: 50px;
    height: 50px;
    color: white;
    font-weight: bold;
    cursor: pointer;
}

.customer_card_logo > .material-icons-outlined {
    align-self: center;
    justify-self: center;
    font-size: 2rem;
    transition: all 0.4s;
}
.customer_card_logo:hover > .material-icons-outlined {
    transform: rotate(90deg);
}

.customer_card_name {
    display: block;
    font-weight: 600;
    font-size: 1.5rem;
}

.customer_card_addresse {
    font-size: 1.2rem;
}

这是我的 HTML 

<head><link href="https://fonts.googleapis.com/css?family=Material+Icons|Material+Icons+Outlined|Material+Icons+Two+Tone|Material+Icons+Round|Material+Icons+Sharp" rel="stylesheet"></head>

<div class="customer_card">
<div class="customer_card_logo"><span class="material-icons-outlined"> autorenew </span></div>
<div class="customer_card_informations">
    <span class="customer_card_name">Company Name</span>
    <span class="customer_card_addresse">Adresse <br> ZIP CITY NAME</span>
</div>

有人知道问题出在哪里吗？ 谢谢！

“条纹元素”只是您在此处定义的网格间隙（不会导致居中问题）：

.customer_card


要使图标居中，请使用 
gap: 0px 10px;

 替换基于宽度/高度的方法。这样，您就不必担心图标的大小可能导致错位：
padding


尝试下面修改后的代码片段：






.customer_card_logo {
    /* width: 50px; */
    /* height: 50px; */
    padding: 0.5rem;
}



.customer_card {
  background: green;
  padding: 10px;
  margin-bottom: 20px;
  border-radius: 10px;
  display: grid;
  grid-template-columns: 20% 80%;
  gap: 0px 10px;
  justify-content: center;
  justify-items: stretch;
  align-items: center;
}

.customer_card_logo {
  display: flex;
  position: relative;
  justify-self: center;
  text-align: center;
  background: grey;
  border-radius: 50%;
  #width: 50px;
  #height: 50px;
  padding: 0.5rem;
  color: white;
  font-weight: bold;
  cursor: pointer;
}

.customer_card_logo>.material-icons-outlined {
  align-self: center;
  justify-self: center;
  font-size: 2rem;
  transition: all 0.4s;
}

.customer_card_logo:hover>.material-icons-outlined {
  transform: rotate(90deg);
}

.customer_card_name {
  display: block;
  font-weight: 600;
  font-size: 1.5rem;
}

.customer_card_addresse {
  font-size: 1.2rem;
}
