html - ASP.NET 显示的图标不同于 HTML/CSS

Question

我在尝试将 HTML/CSS 传输到 ASP.NET 时遇到问题。在 HTML 中，我的图标显示在 1 行中，来自 4 个图标，对于移动设备，显示在 2x2 行中。现在我实际上是在复制粘贴 HTML 并做一些小改动，比如更改/> 结束标记。但现在它在 PC 上也显示 2x2 行，而它应该是 1 行和 4 个图标。我仍然是一名学生并且在这方面非常菜鸟，所以我很感激你的帮助，因为它是为了我的论文。提前致谢。 (下面的代码)

  @import url(https://fonts.googleapis.com/css?family=Fjalla+One);

  html, body {
    height: 100%;
    width: 100%;
    overflow-x: hidden;
  }

  body{
