如何用H5+CSS+JS写一个简单的招聘网站

大家好，我是猿码叔叔，一个 Java 语言开发者。应网友要求，写一个简单的招聘页面。由于技术原因，页面相对简单，朋友们可以选择性的阅读，如果对您有帮助，也可直接拿去使用，因为接下来除了闲言碎语还有源代码干货。

一、内容介绍

这个简单的招聘网站，具备简单的响应式功能。页面元素包含：横向菜单、职位搜索与选择、简历表格、轮播图。页面没有实现与后端交互的功能，后续有需要可以更新，包括更丰富的功能都可以持续更新与扩展。

二、谈谈我对响应式的理解

• 布局

我们应当做好页面的布局设计。一般的网站布局都会大致分为 Header、Body 和 Footer 以及 Others 四个部分。对于前三个部分仍然可以再细分为相应的“块”，每个块包含相应要展示的内容。这些块可以是竖着排列，或者是横向并排排列，亦或是复杂的瀑布式排列。排列的布局应当符合人类的基本审美标准，比如对称、右重左轻等等。

• 自适应调整

自适应调整就是根据不同的设备来调整页面的属性，达到不同的设备布局仍然排列有序，符合我们的审美标准。这一点是建立在我们事先做好了页面布局的工作。

常见的自适应调整，我们可以使用 @media、flex、grid 和 multiCol 来实现。具体的功能大家可以去阅读?MDN Web Docshttps://developer.mozilla.org/en-US/docs/Learn/CSS/CSS_layout/Responsive_Design

这篇文章详细介绍了以上属性的各个功能。

三、代码
