顺风 CSS 背景位置

原文:https://www . geesforgeks . org/tail wind-CSS-background-position/

该类在顺风 CSS 中接受多个值。所有的属性都包含在类的形式中。它是 CSS 背景位置属性的替代物。此类用于为元素设置一个或多个背景图像。默认情况下,它将图像放在左上角。要指定两个或多个图像,请用逗号分隔 URL。

背景位置类别:

  • BG-左上方:位于背景的左上方
  • bg-top: 位于背景的顶部
  • BG-右上方:位于背景的右上方
  • bg-left: 位于背景的左侧
  • bg-center: 位于背景的中心
  • bg-right: 位于背景的右侧
  • BG-左下:位于背景的左下
  • bg-bottom: 位于背景的底部
  • BG-右下方:位于背景的右下方

注:以下示例中使用了所有类。

语法:

<element class="bg-{side}">...</element>
