我想画正方形只是背景，但是我的问题是包含。

当我在网络顶部绘制正方形时。我以前的代码（登录表格）会坏了。

我认为它包含，但是我不知道如何解决它。

谢谢您的帮助。

我可以删除红色部分吗？我希望我的登录表单居中，但现在不正确了

解决方法

从.contain类中删除高度，并使用绝对位置添加按钮

html,body {
  height: 100%;
  font: 30px "2005_iannnnnCPU";
}

body {
  margin: 0;
  padding: 0;
  background: #000;
}

.grid-container {
  display: grid;
  height: 100%;
  color: #fff;
  justify-items: center;
  align-items: center;
}

/*
.square {
    height: 50px;
    width: 50px;
    background-color: #fff;
}
*/

.contain {
  display: grid;
  padding: 15px 15px 50px;/*New css*/
  width: 60%;
  /*height: 23%;*/
  border: 3px solid #fff;
  color: #fff;
  position: relative;/*New css*/
  margin-bottom: 60px; /*New css*/ 
}

.grid-items {
  margin: 1% 1%;
}

.ans {
  margin: 1% 1%;
  font: 20px "2005_iannnnnCPU";
  letter-spacing: 2px;
}

input[type=text] {
  background-color: none;
  background: transparent;
  border: 2px solid #555;
  color: #fff;
}

input[type=text]:focus {
  border: 2px solid #fff;
}

textarea:focus,input:focus {
  outline: none;
}

.button {
  border: none;
  color: white;
  padding: 2% 2%;
  margin: 6% 6%;
  text-align: center;
  text-decoration: none;
  cursor: pointer;
  outline: none;
}

.login {
  background-color: #000;
  font: 30px "2005_iannnnnCPU";
  color: #fff;
  border: 2px solid #fff;
  width: 50%;
  -ms-transform: translateX(40%);
  transform: translateX(40%);
  position: absolute;
  bottom: -50px;
}

.login:focus {
  background-color: white;
  color: black;
  font-weight: bold;
}

问题出在您的

.contain { height: 23%;};

我将其更改为65％，并且可以在代码段中使用，但您应该尝试将其设置为所需的显示高度。

html,body {
  height: 100%;
  font: 30px "2005_iannnnnCPU";
}

body {
  margin: 0;
  padding: 0;
  background: #000;
}

.grid-container {
  display: grid;
  height: 100%;
  color: #fff;
  justify-items: center;
  align-items: center;
}


/*
    .square {
        height: 50px;
        width: 50px;
        background-color: #fff;
    }
    */

.contain {
  display: grid;
  padding: 15px;
  width: 60%;
  height: 65%;
  border: 3px solid #fff;
  color: #fff;
}

.grid-items {
  margin: 1% 1%;
}

.ans {
  margin: 1% 1%;
  font: 20px "2005_iannnnnCPU";
  letter-spacing: 2px;
}

input[type=text] {
  background-color: none;
  background: transparent;
  border: 2px solid #555;
  color: #fff;
}

input[type=text]:focus {
  border: 2px solid #fff;
}

textarea:focus,input:focus {
  outline: none;
}

.button {
  border: none;
  color: white;
  padding: 2% 2%;
  margin: 6% 6%;
  text-align: center;
  text-decoration: none;
  cursor: pointer;
  outline: none;
}

.login {
  background-color: #000;
  font: 30px "2005_iannnnnCPU";
  color: #fff;
  border: 2px solid #fff;
  width: 50%;
  -ms-transform: translateX(40%);
  transform: translateX(40%);
}

.login:focus {
  background-color: white;
  color: black;
  font-weight: bold;
}

为什么不是字段集：
