仅倾斜/倾斜 div 的底部 [重复]
Posted
技术标签:
【中文标题】仅倾斜/倾斜 div 的底部 [重复]【英文标题】：Slant/Skew only bottom of div [duplicate] 【发布时间】：2016-12-25 11:11:26 【问题描述】：我一直在尝试在div 的底部添加倾斜/倾斜。我已经取得了一些成功，正如您在下面的示例中看到的那样，我已经成功地将偏斜应用于页面上的几个元素。
目前，Skew 应用于容器的顶部和底部，它似乎在底部和顶部的一半处停止，然后回到直边。
我想要实现的是上边缘是直的，而下边缘是倾斜的，例如：

【问题讨论】：
您可以使用伪元素来实现这一点。请您在问题本身中包含所有相关代码，以便我们重现您的问题。外部链接不适合，因为可能会死掉或问题得到解决，使这个问题失去上下文。 你好，我已经包含了我所有的自定义 CSS。其他代码由 wordpress 和革命滑块生成。如果将其粘贴进去，那对您有用吗？ 嗨@Chris，我们需要的是一个最小的例子***.com/help/mcve。在这种情况下，ID 为#main-slideshow 的div 的HTML 可能就是我们需要的以及影响它的所有样式。
我希望我添加的内容是有用的，rev 滑块的很多样式似乎都在 HTML 中。
我认为它不起作用，因为 Revolution Slider 是通过 CSS 插入图像，而这需要一个实际的图像标签。
【参考方案1】：
您可以使用伪元素和 CSS 三角形来实现此效果
除了使用skew 来改变整个盒子的视角，您还可以使用伪元素在图像顶部覆盖一个三角形，以产生倾斜盒子的效果。
这种技术的一般原理是：
使用:after 伪元素允许将内容添加到页面而不需要额外的标记
使用 CSS 三角形将这个伪元素变成一个倾斜的三角形（与页面背景颜色相同），它跨越了框的宽度。这给人的印象是盒子本身是倾斜的
需要进行以下修改：
从#main-slideshow 和.tp-bgimg 中删除transform 属性
添加规则.tp-bgimg:after 以创建伪元素。将以下值添加到此规则：
border-color: transparent transparent #FFFFFF transparent;、border-style: solid;、border-width: 0 0 10vw 100vw;、height: 0; 和 width: 0; 创建三角形。由于图像跨越页面视口的整个宽度，因此可以使用单元来使三角形响应
bottom: 0;、position: absolute; 和 left: 0; 将三角形定位在容器底部
content: ""; 是伪元素出现所必需的

嘿@Hidden-Hobbes 是否可以以相同的方式运行倾斜但在 div 的顶部而不是底部？还是从右往左走。我试过玩你的css并设法改变某些东西，但不能完全得到我想要的。谢谢 @Chris。是的，更改边框以修改三角形的方向并将其定位在top 而不是bottom。 jsfiddle.net/yc9n0jpm
非常感谢。我颠倒了边界，但没有从下到上改变。
没问题@Chris。以上是关于仅倾斜/倾斜 div 的底部 [重复]的主要内容，如果未能解决你的问题，请参考以下文章
