CSS样式仅适用于chrome

Question

我正在尝试自学网页设计，并且刚刚开始掌握基础知识。我刚刚为一家假想的餐厅完成了我的练习网站的内容，并为此感到非常自豪，因为它在谷歌浏览器中完美运行，但当我检查它在IE和Firefox中的外观时，似乎CSS样式不是完全注册。

这是主页的代码。该网站还包含图像和其他页面的链接，但我真正关心的是让CSS在所有浏览器中正确应用。

            Frontier's Concept
          </h1>
          <p>
        Frontier is the first franchise developed by former President of the U.S. Theodore Roosevelt.
        Teddy, as he is known to his friends and family, always had a dream of creating
        a breakfast house that captured the look and feel of a specific time and place that was
        very dear to him.</p>
        <p>
          Frontier is the realization of that dream. Tucked away in the heart of the pocono mountains,
          our establishment seeks to give our guests not only a delicious breakfast, but a completely immersive
          experience as well.</p>
