删除输入文本框的粗体框

Question

目标：
仅删除输入文本框框架的粗体。没有input textboxs frame的粗体看起来是一样的，它应该是一个简单的框架。

问题：
当您使用 css 与背景图像、背景大小、背景位置相关的代码时，输入文本框框架非常粗体。
如果删除这3个语法代码，输入文本框的粗体将消失，但不会显示图标大小和图片。

我仍然想保留所有没有输入文本框粗体框架的内容，只想要一个简单的单一框架，可以吗？

谢谢！

Answer 1

您可以使用 border:0; 将边框移除到您的 css 中，或者您可以使用 border: 1px solid;

使用细边框

input.date_picker {
  text-align: center;
  
  background-image: url("https://upload.wikimedia.org/wikipedia/commons/7/71/X-office-calendar.svg");
  background-size: 16px 16px;
  background-position: right center;
  border: 1px solid;
  background-repeat: no-repeat;
  padding-right: 18px;
  width: 78px;
}
