接下来,我对CSS做一个小小的总结.不全面之处大家勿怪~

CSS官方的定义为"层叠样式表".引入方式一共分为四种:

常用的分为内嵌样式,内部样式,外部样式三总,外加@import不常用方式一种.这四种是针对CSS与HTML文件的关系而划分.

这里我采用外部样式在<head>标签中使用<stytle>标签将CSS进行引入.

CSS选择器分为基本选择器(元素选择器,id选择器,class选择器),属性选择器,伪元素选择器三种.

其中,元素选择器书写语法为: html标签名 {CSS属性}

id选择器书写语法为: #(id) {CSS属性}

class选择器书写语法为: .class的值 {CSS属性}

属性选择器语法为: 基本选择器[属性='属性值'] {CSS属性}

伪元素选择器最为有趣,可以使一个对象根据鼠标悬浮点击事件分为四个状态: 静止,悬浮,触发,完成

当鼠标不触及该元素时,可使用 a:link {CSS属性} 对其进行设置 -----静止状态

当鼠标触及该控件时,可使用 a:hover {CSS属性} 对其进行设置 -----悬浮状态
