+### HTML 基本概念
+对于UI书写划分为两类, 一是外观样式, 一是结构关系
+一个元素的基本构成就是其外观样式, 因此它书写在声明它的同一列
+```javascript
+div.w(128).h(64)
+```
+
+嵌套关系则应该换行并缩进, 保持与 HTML 一致的风格
+```javascript
+document.body.appendChild(div.w(128).h(64).children([
+    div.text('Hello world!'),
+    div.text('Hello world!'),
+    div.text('Hello world!')
+]))
+```
+
+有时期望复用样式
+```javascript
+const option = { style: { width: '128px', height: '64px' } }
+div(option).children([
+    div.text('Hello world!'),
+    div.text('Hello world!'),
+    div.text('Hello world!')
+])
