scrollbar-color属性

scrollbar-color属性用于设置元素滚动条的颜色。它可用于分别控制滚动条轨道和滚动条拇指的颜色。滚动条的轨迹是滚动条的背景,它保持固定并显示可以滚动的区域。滚动条的拇指指的是滚动条的移动部分,该部分浮点数在轨道的顶部,表示滚动条的当前位置。

  • track(轨道)是指滚动条,其一般是固定的而不管滚动位置的背景。

  • thumb(拇指)是指滚动条通常漂浮在轨道的顶部上的移动部分。

语法:

scrollbar-color:auto | color | dark | light
scrollbar-color: auto; /* 使用浏览器默认的滚动条样式 */

scrollbar-color: dark; /* 使用浏览器默认的深色或者黑色滚动效果 */

scrollbar-color: light; /* 使用浏览器默认的浅色滚动效果 */

scrollbar-color: red #00f; /* 第一个颜色为滚动条的颜色, 第二个颜色为滚动条轨道的颜色 */
