css - 使用 css 网格对齐面板主体内的输入框

Question

我使用 CSS 网格布局创建了一个登录。我想在面板主体内实现一个表单输入框。但是，输入框不尊重面板主体内部。输入框溢出面板主体。出于某种原因，代码正在使用常规 css。我只想实现 css 网格，但我不确定是否要着手去做。

感谢您的帮助。

Answer 1

只要使用*{box-sizing: border-box}就会更新。希望对您有所帮助。请检查代码段。由于 CSS3 box-sizing 属性允许我们在元素的总宽度和高度中包含填充和边框。

body {
	margin: 0;
	font-size: 13px;
	color: #222;
	background-color: #f5f5f5;
}

* {
  box-sizing:border-box;
}
