git出自己对应版本的，看好第一步的版本号!!1git checkout workstation-16.2.3
下面按顺序执行就完了1make
1make install
1sudo /etc/init.d/vmware start
完事打开新终端1sudo su
1sudo vmware

2.每个HTML元素是一个元素节点
3.HTML元素内文本是文本节点
4.HTML属性是属性节点
使用DOM树能干什么1.JavaScript 能够改变页面中的所有HTML元素
2.JavaScript 能够改变页面中的所有HTML属性
3.JavaScript 能够改变页面中的所有CSS样式
4.JavaScript 能对页面中所有事件作出反应
简介JavaScript是由美国网景通信公司开发的一种跨平台网页，面向对象object-oriented网页脚本语言
JavaScript代码可以直接嵌入HTML文件中，随着网页一起传送到客户端浏览器，然后通过浏览器来解释执行
JS是前端开发的的核心语言，基于事件和驱动的解释性，松散型语言
JS的解释性，松散型理解？
1. 解释性：边执行边解释，在浏览器环境下运行
2. 松散型：定义变量的时候，不需要强类型，直接弱类型，定义的变量不需要声明类型
特点1. 脚本编写语言
2. 基于对象
可以被看作是一种面向对象的语言，这意味着JavaScript能运用其已经创建的对象。因此 ...</div></div></div><div class="recent-post-item"><div class="post_cover right"><a href="/posts/css-note.html" title="CSS学习笔记"><img class="post_bg" src="https://github.com/PCKxin/ID-0202/blob/master/img/top-img/brak-p1.jpg?raw=true" onerror="this.onerror=null;this.src='https://github.com/PCKxin/ID-0202/blob/master/img/main-body/404-01.png?raw=true'" alt="CSS学习笔记"></a></div><div class="recent-post-info"><a class="article-title" href="/posts/css-note.html" title="CSS学习笔记">CSS学习笔记</a><div class="article-meta-wrap"><span class="post-meta-date"><i class="far fa-calendar-alt"></i><span class="article-meta-label">Created</span><time datetime="2022-11-03T01:32:57.000Z" title="Created 2022-11-03 09:32:57">2022-11-03</time></span><span class="article-meta"><span class="article-meta-separator">|</span><i class="fas fa-inbox"></i><a class="article-meta__categories" href="/categories/StudyNote/">StudyNote</a></span><span class="article-meta tags"><span class="article-meta-separator">|</span><i class="fas fa-tag"></i><a class="article-meta__tags" href="/tags/Note/">Note</a><span class="article-meta-link">•</span><a class="article-meta__tags" href="/tags/%E5%89%8D%E7%AB%AF%E4%B8%89%E5%89%91%E5%AE%A2/">前端三剑客</a><span class="article-meta-link">•</span><a class="article-meta__tags" href="/tags/CSS/">CSS</a></span></div><div class="content">说明CSS 指的是“Cascading style sheet” 层叠样式表
控制网页外观的语言
HTML 是网页结构 CSS 是网页外观 JavaScript是网页的功能行为
样式表引入方式1. 外部样式表
2. 内部样式表
3. 行内样式表
内部样式表指的是把HTML代码和CSS代码放到同一个HTML文件中
语法：
<style type="text/css">
</style>
行内样式表内部样式表的CSS是在"style标签"内定义的，而行内样式表的CSS是在"标签的style属性"中来定义的
外部样式表外部样式表在单独文件中定义，然后在HTML文件的<head></head>标签中使用link标签引用
语法：
