p表示自然段落,默认上下会有行间距
br是换行,自闭合标签
hr是横线
a标签
1.可添加超链接标签

select标签
<!DOCTYPE html><html lang="zh"><head> ???<meta charset="UTF-8" /> ???<meta name="viewport" content="width=device-width, initial-scale=1.0" /> ???<meta http-equiv="X-UA-Compatible" content="ie=edge" /> ???<title>Document</title></head><body> ???<h1>单选</h1> ???<select name=""> ???????<option value="1">Jay</option> ???????<option value="2">范特西</option> ???????<option value="3" disabled="true">我不能选</option> ???????<option value="4" selected="selected">我是默认选项</option> ???</select>
???<h1>多选</h1> ???<select multiple="multiple" size="6"> ???????<option value="1">七里香</option> ???????<option value="2">依然范特西</option> ???????<option value="3">十二新座</option> ???????<option value="4">惊叹号</option> ???</select>
???<h1>分组</h1> ???<select name=""> ???????<optgroup ?label="第一组"> ???????????<option value="1">我是第一组的1号</option> ???????????<option value="2">我是第一组的2号</option> ????????</optgroup> ???????<optgroup ?label="第二组"> ???????????<option value="1">我是第二组的1号</option> ???????????<option value="2">我是第二组的2号</option> ????????</optgroup> ???</select></body></html>
效果如图
在单选中,通过 disabled="true" 和 selected="selected"来控制是否可选和默认显示项
在多选中,通过multiple来设置多选,size=$i 控制初始显示几个选项
分组中,用<optgroup label="第一组">来进行设置
