定义和用法

border-color 属性用于设置元素的四个边框的颜色。此属性可以包含一到四个值。

如果 border-color 属性有四个值

  • border-color: red green blue pink;
    • 顶部边框为红色
    • 右侧边框为绿色
    • 底部边框为蓝色
    • 左侧边框为粉色

如果 border-color 属性有三个值

  • border-color: red green blue;
    • 顶部边框为红色
    • 右侧和左侧边框为绿色
    • 底部边框为蓝色

如果 border-color 属性有两个值

  • border-color: red green;
    • 顶部和底部边框为红色
    • 右侧和左侧边框为绿色

如果 border-color 属性有一个值

  • border-color: red;
    • 所有四个边框均为红色

注意: 务必先声明 border-style 属性,然后再声明 border-color 属性。元素必须先有边框才能更改颜色。
