CSS div 对齐到底部中心

如何解决CSS div 对齐到底部中心

我正在尝试将我的 <div class="social-icons"> 与侧边栏的底部中心对齐。井图标在页面底部，但在左侧。

我的代码：

@font-face {
  font-family: 'FontAwesome';
  src: url('../fonts/fontawesome-webfont.eot?v=4.2.0');
  src: url('../fonts/fontawesome-webfont.eot?#iefix&v=4.2.0') format('embedded-opentype'),url('../fonts/fontawesome-webfont.woff?v=4.2.0') format('woff'),url('../fonts/fontawesome-webfont.ttf?v=4.2.0') format('truetype'),url('../fonts/fontawesome-webfont.svg?v=4.2.0#fontawesomeregular') format('svg');
  font-weight: normal;
  font-style: normal;
}

解决方法

如果您为社交图标提供宽度，您可以将您的项目居中对齐。

如下所示；

.social-icons {
                padding: 30px 40px;
                position: fixed;
                bottom: 0;
                margin: auto;
                text-align: center;
                width: 100%;
    
            }

使用这个：

.social-icons {
    padding: 30px 40px;
    position: absolute;
    bottom: 0;
    margin: auto;
    text-align: center;
    width: 100%;
    left: 0;
    right: 0;
}
