html - 无法在页脚中居中社交媒体图标

Question

我被一个问题困扰了 2 天多了，我需要寻求帮助。在桌面浏览器上，图标应该左对齐，而在移动浏览器中，图标应该居中对齐。

这是目前为止的网站。

我创建了一个网站，其中的布局由堆叠的部分组成，其中每个部分的高度和宽度值使用 VH 百分比定义以获得特定布局。

这是如何在 CSS 中定义部分的示例。

.content3 {
height: 100vh;
width: 100%;
display: table;
background: #FFFFFF url('../img/chair.png') no-repeat center center;
background-size: 60%;
}

这是我定义页脚 CSS 的方式。

.footer {
height: 40vh;
width: 100%;
background: #312D3B;
}

这是 .footer 的 HTML

<section class="footer">
<div class="Social">
    <img class="icons" src="img/dribbble.svg">
    <img class="icons2" src="img/twitter.svg">
    <img class="icons3" src="img/instagram.svg">
</div>  

这是 .Social 类的 CSS

.Social {
height: 100%;
float: left;
position: relative;
}

这是 .icons 类的 CSS

.icons {
    bottom: 0;
    left: 0;
    margin: auto;
    position: absolute;
    right: 0;
    top: 0;
    padding-left: 3.5em;
    }

这是 .icons2 类的 CSS

    .icons2 {
    bottom: 0;
    left: 4.5em;
    margin: auto;
    position: absolute;
    right: 0;
    top: 0;
    padding-left: 3.5em;
    }

这是 icons3 类的 css

.icons3 {
    bottom: 0;
    left: 9em;
    margin: auto;
    position: absolute;
    right: 0;
    top: 0;
    padding-left: 3.5em;
    }

请帮忙。这是我在这个网站上的第一个问题。

你可以使用 flexbox 来帮助你解决这个问题，只需将 style.css 代码替换为这个即可

CSS:

/* -------------------------------- 

Primary style

-------------------------------- */
*, *::after, *::before {
  box-sizing: border-box;
}

body {
  font-family: sans-serif;
  line-height: 1;
  margin: 0;
  width: 100%;
  height: 100%;
  background: #1C1D21;
}

/* -------------------------------- 

Final project

-------------------------------- */
