Safari 上不显示输入和文本区域边框

Question

我的表单边框在除 Safari 之外的所有浏览器上都显示得很好。有时它们根本不出现，有时缺少一个边缘。任何帮助都是极好的。你可以去这里看看http://cmweb.design

将边框宽度 0.5 更改为 1

没有半个像素这样的单位:)

最小值为 1px，显然有些浏览器将其四舍五入为 1，而其他浏览器则四舍五入为 0px。

HTML: Sub-pixel border.

  background-color: #181818;
  border-color: #cfcfcf;
  border-width: 0px 0px 1px 0px;
  border-radius: 0;
  -moz-border-radius: 0;
  -webkit-border-radius: 0;
  border-style: solid;

  margin-right: 20px;
  margin-top: 21px;
