在构建响应式网页时，我发现网站是通过两种方法构建的
示例 1 - 这是使用引导程序的示例，其中选项卡随着屏幕尺寸的减小而重新定向 https://www.w3schools.com/howto/howto_js_topnav_responsive.asp
示例 2 - 随着屏幕尺寸的减小，整个页面尺寸也会减小的另一种方法。即使在缩小的尺寸下，页面的格式仍然完好无损 Mobile compare website Herbarium website
尝试缩小网页大小以了解两个样本的差异
问题是 - 我无法理解如何按照示例 2 设计页面。如何根据示例 2 转换示例 1（下面的代码）中的网页？ 我对前端技术很陌生，因此请求帮助。
