html - 页面在 html 和 css 中没有一直滚动到底部

标签 html css

我已经使用 html 和 css 创建了一个注册表单。早些时候只有 7 个输入字段,因为我想要 2 个输入字段,所以我又添加了 2 个文本框来输入用户名和密码。

当它只有七个文本框时,它会向我显示提交按钮。但是在我添加了额外的文本框之后,尽管我向下滚动,但它不会显示注册按钮

这里我没有包括php代码,因为它没有任何问题

这是CSS代码:

@charset "utf-8";
/* CSS Document */
@charset "utf-8";
/* CSS Document */

body{
    margin: 0;
    padding: 0;
    min-height: 100%;
    background-color: white;
	background-position: center;
    background-blend-mode: soft-light;
    font-family: sans-serif;
    
}

#form1
{
    overflow: scroll;
}

.regform
{
	
 	width: 500px;
    height: 880px;
    overflow-y:scroll;
    background:rgba(0,0,0,0.5);
    color: #fff;
	padding: 0px;
    position: fixed;
    top: 50%;
    left: 50%;
    transform: translate(-50%,-50%);
    box-sizing: border-box; 
    padding: 70px 30px;
    
	
	
}

.regform p
{
	 margin: 0;
    padding: 0;
    font-weight: bold;
	
}

.regform input[type="text"],[type="datetime-local"] ,[type="date"],[type="Password"]{
	
	 width: 100%;
    margin-bottom: 20px;
	 border: none;
    border-bottom: 1px solid #fff;
    background: transparent;
    outline: none;
    height: 40px;
    color: #fff;
    font-size: 16px;
}

#regbt{
	
	width: 85%;
	position: fixed;
	border: none;
    outline: none;
	
    height: 40px;
    background: blue;
    color: #fff;
    font-size: 18px;
    border-radius: 20px;
	margin:9px 0;
	
}

#regbt:hover{
	
	 cursor: pointer;
    background: #ffc107;
    color: #000;
	
}

这是html代码:

请忽略我在发布问题时所做的任何错误。

最佳答案

您正在为您的 .regform 设置固定的高度尺寸

更新如下:

.regform {
    width: 500px;
    height: 100%;
    [...]
}

@charset "utf-8";
/* CSS Document */
@charset "utf-8";

    font-family: sans-serif;
    
}

#form1

    overflow: scroll;
}

.regform
