我需要提供一些数据。每个数据 block 都需要一个国家标志。我想使用一个漂亮的小悬挂横幅来显示国旗,如下所示:
此图像是在 Paint 中编辑的,我使用的示例来自 this page
此链接正确here, shows how to display flags of Europe++ in pure CSS 。在我的系统中,我只需要北欧旗帜,这些旗帜都用十字表示。
来自 codepen 示例:
@function cross($back, $main, $detail: $back){
@return linear-gradient(90deg, transparent 28%, $main 28%, $main 34%, transparent 34%),
linear-gradient(transparent 42%, $detail 42%, $detail 46%, $main 46%, $main 58%, $detail 58%, $detail 62%, transparent 62%),
linear-gradient(90deg, $back 25%, $detail 25%, $detail 28%, $main 28%, $main 34%, $detail 34%, $detail 37%, $back 37%);
}
如果我导出这个(并将其旋转 90 度以适合我的首选方向,我可以得到类似 this 的东西:
HTML:
<div class="norway"></div>
CSS:
.norway{
background: linear-gradient(180deg, transparent 28%, blue 28%, blue 34%, transparent 34%),
linear-gradient(90deg, transparent 42%, white 42%, white 46%, blue 46%,
blue 58%, white 58%, white 62%, transparent 62%),
linear-gradient(180deg, red 25%, white 25%, white 28%, blue 28%, blue 34%,
white 34%, white 37%, red 37%);
height: 600px;
width: 400px;
}
然而,悬挂横幅示例并没有真正显示元素本身,而只是显示其边框。我喜欢底部的分割,所以我希望能够单独设置不同边框侧的线性渐变,或者以其他方式解决问题。我尝试了几种方法,但我似乎无法使渐变在各个边框侧起作用。
有谁知道如何仅使用 CSS 将我的标志显示为 fork 丝带?
顺便说一下,Czech Republic is easy...
更新: 我能够渲染挪威语版本,但我必须制作两个元素。一个在元素的背景中显示标志,另一个元素在其上方,仅显示底部边框,颜色与 block 背景相同。不过,这似乎是一个非常脆弱的解决方案...... https://jsfiddle.net/azjctc1y/
最佳答案
Note: After looking at Joseph's answer, I'd suggest you to go with that but this is another way.
我们可以使用带有线性渐变
图像的背景
,而不是使用边框
来创建标志,如下面的代码片段所示。

原始答案:
它并不 100% 像所提供的图像或 fiddle 的输出,因为蓝色十字没有小三 Angular 形切口,因为我试图创建一个透明的切口(这样你就可以在具有任何背景的元素的顶部)。但如果它始终是灰色背景,那么也可以这样做。
以下是我添加的代码:
