html5该怎么学-海普生-哪可以学-静秋百科网

` + `

`，鲁棒性高，扩展性也强。不懂就查 GitHub。Google 搜 `html5 example` 这种，直接翻那些团队写的开源项目。
看他们如何把文档结构变成代码。你会发现，一个标准的百科词条，往往就是几千行代码拼出来的。别被那些复杂的缩进、格式化吓住，本质就是 `

`, `

` 的堆叠。网上有教程，但别全信。有些道地的老手会告诉你，HTML5 最难的就是本地化。浏览器不认本地文件，得转成 `file://` 协议。
这时候你就得学会用 `file:///D:/MyFile.html` 这种写法去写本地文件。还有个坑是 `iframe`。
那会儿认定 iframe 是独立的，目前发现它还是嵌在文档里，只是换了个窗口。和 `<div>` 本质一样，只是多了一个 `sandbox` 属性，用来管住沙箱权限。<br>比如不让 iframe 跳转外网，要么不准点击链接。想深入一点，了解一下 CSS 和 HTML5 的联动。<br>不要试图一次性把页面做得漂漂亮亮。先搞定内容结构，再谈样式。CSS 里的 `display`, `flexbox`, `grid` 这些新特性，有时候比 HTML 标签还调皮。HTML 管结构，CSS 管样子，两者配合才能出门。别急着写大项目。先试着写页面上的某个小功能。<br>比如做一个购物车，要么一个表单。你会发现，写代码的过程实际上就是学习过程。每一个 `input` 的验证，每一个 `button` 的点击事件，都是对页面逻辑的掌控。最终再说说心态。学 HTML5 最好办遇到的阶段就是“迷茫期”。<br>看了好多新标签，当作掌握了就万事大吉，结局写出来的页面结构混乱。<br>这时候就把自己当成一个考古学家，去挖掘那些老文档的底层逻辑。还有，别怕出错。页面里的 `contenteditable` 特性，有时候改一下会出奇迹。原生代码别看少，但逻辑多了。总而言之，HTML5 不是一堆静态的标签，而是构建信息的砖瓦。把它学通，你就掌握了网页的神经系统。别迷信教程的权威，多动手敲，多读源码，多去体验浏览器在不同引擎下的渲染差异。<br>这才是真本事。 <div>好文推荐：：<li><a href="http://des.2zaojia.cn/article/10/610170.html"
