文字


语法:

border-bottom-left-radius:[ <length> | <percentage> ]{1,2}

默认值0

适用于:所有元素

继承性:无

动画性:是

计算值:指定值

取值:

  • <length>:

  • 用长度值设置对象的左下角(bottom-left)圆角半径长度。不允许负值

  • <percentage>:

  • 用百分比设置对象的左下角(bottom-left)圆角半径长度。不允许负值

说明:

设置或检索对象的左下角圆角边框。提供2个参数,2个参数以空格分隔,每个参数允许设置1个参数值,第1个参数表示水平半径,第2个参数表示垂直半径,如第2个参数省略,则默认等于第1个参数
  • 如设置border-bottom-left-radius:5px 10px表示bottom-left这个角的水平圆角半径为5px,垂直圆角半径为10px。

  • 对应的脚本特性为borderBottomLeftRadius

兼容性:

  1. Firefox从13.0开始移除对-moz-的支持,仅支持标准的border-radius写法,在4.0-12.0区间,两种方式都支持。

  2. Firefox支持的厂商前缀写法是非标准的-moz-border-radius-bottomleft,而不是-moz-border-bottom-left-radius
