文字

语法：

border-top-style：<line-style>

<line-style> = none | hidden | dotted | dashed | solid | double | groove | ridge | inset | outset

默认值：none

适用于：所有元素

继承性：无

动画性：否

计算值：指定值

相关属性：[ border-style ] || [ border-right-style ] || [ border-bottom-style ] || [ border-left-style ]

取值：

  • none：无轮廓。border-color将被忽略，border-width计算值为0，除非边框轮廓为图像，即border-image。

  • hidden：隐藏边框。IE7及以下尚不支持

  • dotted：点状轮廓。IE6下显示为dashed效果

  • dashed：虚线轮廓。

  • solid：实线轮廓

  • double：双线轮廓。两条单线与其间隔的和等于指定的border-width值

  • groove：3D凹槽轮廓。

  • ridge：3D凸槽轮廓。

  • inset：3D凹边轮廓。

  • outset：3D凸边轮廓。

说明：

设置或检索对象的顶部边框样式。

  • 如果border-width等于0，本属性将失去作用。

  • 对应的脚本特性为borderTopStyle。

兼容性：

  • 浅绿 = 支持

  • 红色 = 不支持
