我制作了一个网页 - Campus Connect - Colleges。但是，在移动设备上查看此功能会隐藏组的按钮。而且，按钮不会显示居中。
整个页面代码是 -

错误是什么？我该如何解决这个问题？
答案 0 :(得分：1)
你的粘性页脚是罪魁祸首。在sticky-footer-navbar.css第25行中，添加第三个填充值为100px可以解决问题：
body > .container {
padding: 60px 15px 100px;
}
如果我是你，我也会摆脱内联造型。您已在所有段落上添加了文本对齐样式，而不是在样式表中定义规则。此外，您可以使按钮位于成像下方的中心位置：
style: block;
margin: 0 auto;

margin-left=30%。text-align: center添加到
包装元素。
