通过了解网页的数据编码，理解网页的数据请求与响应过程；通过体验网页表单，了解网页表单数据交互的过程。
1、你知道网页是如何实现交互的吗?
2、你知道网页数据有哪些编码方式?
你知道什么是网页编码？
网页编码是指用于表示和处理网页文本内容的字符编码方法。文本、图像、音频、视频等数据是通过HTML标签编码组织在网页中，再由浏览器解释并呈现。
文本的段落可以使用标签

组织
图像可以使用标签实现将其插入文本中
多媒体的播放可以使用、等标签组织，并能设置播放方式
活动一：使用标签添加图片文件，再尝试使用其他标签。
网页的数据请求与响应
你知道什么是网页的数据请求与响应？
网页需要通过请求与响应以获取HTML数据，网页中如有多个媒体数据，则需要多次请求与响应，才能在网页上呈现。
网页的数据请求与响应：
网页中的交互是指用户与网页之间的互动行为，用户可以通过鼠标、键盘或触摸等输入设备与网页进行交互，而网页则会根据用户的操作做出相应的反馈或执行相应的动作。
1、点击链接2、表单交互3、按钮操作4、鼠标悬停5、下拉菜单6、滚动交互7、轮播图8、弹出框和模态框9、列表排序与过滤10、拖放交互
1、使用标签创建表单2、添加表单字段3、定义表单提交操作4、处理表单数据
在HTML中，使用标签创建表单元素，它会包裹表单中的各个字段和提交按钮。
1、：文本输入框，用于接收用户输入的文本。2、：密码输入框，用于接收用户输入的密码，显示为密文。3、：复选框，允许用户选择一个或多个选项。4、：单选按钮，允许用户从一组选项中选择一个。5、：多行文本输入框，用于接收用户输入的多行文本7、轮播图。<br/> 教师演示创建一个包含文本输入框和提交按钮的表单。<br/> 活动二：制作一张调查家庭使用人工智能设备的网页。 </div> <div
