CSS淡出水平规则/线条风格的div效果,没有图像

ja_*_*him 12 css line shadow shapes fadeout

我是最小化图像使用的忠实粉丝,并且想知道是否有人使用纯静态CSS创建这种类型的策略(或者是否可能)?

我指的是一条似乎越来越瘦的线条和它下面的阴影效果.

我当时认为用三角形做一个CSS形状技巧是可能的:

或者使用'transform'在box-shadow上旋转:

有任何想法吗?

您可以使用CSS3的stop和:afterpseudo-element来实现这样的效果.诀窍是<hr>通过使用:after伪元素为元素添加边框,并将其放置在初始渐变的中心,并使用以渐变结束的柔和颜色.

这是一个快速演示,另一个使用一些颜色的演示.

为了重现该水平规则,您可以使用 CSS3 线性渐变。只需创建一个大约 3px 高度的 div 并应用以下 CSS(根据需要更改颜色):

background: #ffffff; /* Old browsers */
background: -moz-linear-gradient(left,  #ffffff 0%, #2989d8 25%, #207cca 75%, #ffffff 100%); /* FF3.6+ */
background: -webkit-gradient(linear, left top, right top, color-stop(0%,#ffffff), color-stop(25%,#2989d8), color-stop(75%,#207cca), color-stop(100%,#ffffff)); /* Chrome,Safari4+ */
background: -webkit-linear-gradient(left,  #ffffff 0%,#2989d8 25%,#207cca 75%,#ffffff 100%); /* Chrome10+,Safari5.1+ */
background: -o-linear-gradient(left,  #ffffff 0%,#2989d8 25%,#207cca 75%,#ffffff 100%); /* Opera 11.10+ */
background: -ms-linear-gradient(left,  #ffffff 0%,#2989d8 25%,#207cca 75%,#ffffff 100%); /* IE10+ */
background: linear-gradient(left,  #ffffff 0%,#2989d8 25%,#207cca 75%,#ffffff 100%); /* W3C */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#ffffff', endColorstr='#ffffff',GradientType=1 ); /* IE6-9 */

请记住,filter它不支持颜色停止,因此您可能希望图像在 < IE10 后退。

好的,我已经回答了我自己的问题,但我已经阅读了Stackoverflow论坛,它似乎是可以接受的(如果不是真的鼓励!)

所以...
