用h5+css+js写一个登入界面
好的,我可以为您提供一个简单的登陆界面示例代码。以下是 HTML 、CSS 和 JavaScript 代码:
HTML 代码:
```
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Login Page</title>
<link rel="stylesheet" href="style.css">
</head>
<body>
<div class="login-box">

<a href="#">
<span></span>
<span></span>
<span></span>
<span></span>
Submit
</a>
</form>
</div>
</body>
</html>
```
CSS 代码:
```
* {
margin: 0;
padding: 0;
box-sizing: border-box;
}
body {
font-family: sans-serif;
background: #f1f1f1;
}
.login-box {
width: 400px;
height: 500px;
background: #fff;
color: #000;
top: 50%;

position: absolute;
transform: translate(-50%, -50%);
box-shadow: 0 10px 20px rgba(0, 0, 0, 0.5);

animation-delay: 0.25s;
}
@keyframes animate2 {
0% {
top: -100%;
}
50%,

}
.login-box a span:nth-child(3) {

height: 2px;
background: linear-gradient(270deg, transparent, #000);

animation-delay: 0.5s;
}
@keyframes animate3 {
0% {
right: -100%;
}
50%,
100% {

}
}
.login-box a span:nth-child(4) {
bottom: -100%;
left: 0;
width: 2px;
height: 100%;
background: linear-gradient(360deg, transparent, #000);
animation: animate4 1s linear infinite;
animation-delay: 0.75s;
}
@keyframes animate4 {
0% {
bottom: -100%;
}
50%,
100% {
bottom: 100%;
}
}
.login-box a:hover span {
animation: none;
}
.login-box a:hover span:nth-child(1) {
left: 0;
}
.login-box a:hover span:nth-child(2) {
top: 0;
}
.login-box a:hover span:nth-child(3) {
right: 0;
}
.login-box a:hover span:nth-child(4) {
bottom: 0;
}
```
JavaScript 代码:
```
const inputs = document.querySelectorAll(".user-box input");
function addClass() {
let parent = this.parentNode;
parent.classList.add("focus");
}
function removeClass() {
let parent = this.parentNode;
if (this.value == "") {
parent.classList.remove("focus");
}
}
inputs.forEach(input => {
input.addEventListener("focus", addClass);
input.addEventListener("blur", removeClass);
});
```
这段代码将会渲染一个登陆框,包含输入用户名和密码的文本框,以及一个提交按钮。CSS 代码将添加一些样式,而 JavaScript 代码将帮助我们在文本框获得焦点和失去焦点时添加或删除一个类名,以便更好地控制样式。

<footer>

</footer>
<script src="script.js"></script>
</body>
</html>
```
CSS代码:
```
* {
margin: 0;
padding: 0;
box-sizing: border-box;
}
header {
background-color: #f1f1f1;
padding: 20px;
text-align: center;
}
.gallery {
display: grid;
grid-template-columns: repeat(auto-fit, minmax(200px, 1fr));
grid-gap: 20px;
padding: 20px;
}
.gallery img {
width: 100%;
height: auto;
object-fit: cover;
cursor: pointer;
}
.modal {
display: none;
position: fixed;
z-index: 1;
left: 0;
top: 0;
width: 100%;
height: 100%;
overflow: auto;
background-color: rgba(0,0,0,0.9);
}
.modal-content {
margin: auto;
display: block;
max-width: 800px;
max-height: 700px;
}
.modal-content img {
width: 100%;
height: auto;
object-fit: contain;
margin: auto;
display: block;
}
.close {
position: absolute;
top: 20px;
right: 30px;
font-size: 30px;
font-weight: bold;
color: #f1f1f1;
}
.close:hover,
.close:focus {
color: #bbb;
text-decoration: none;
cursor: pointer;
}
```
JavaScript代码:
```
var modal = document.querySelector('.modal');
var modalImg = document.querySelector('.modal-content img');
var gallery = document.querySelector('.gallery');
gallery.addEventListener('click', function(event) {
if (event.target.tagName === 'IMG') {
modal.style.display = 'block';
modalImg.src = event.target.src;
}
});
var close = document.querySelector('.close');
close.addEventListener('click', function() {
modal.style.display = 'none';
});
```
在这个示例中,我们使用了HTML来创建网页的基本结构,CSS来美化页面,并使用JavaScript来添加一些动态效果。其中,相册部分是使用了CSS Grid来进行排版,并使用了JavaScript来实现点击照片显示大图的功能。
