HTML+CSS一个简单却不失美感的登录界面!
以下是一个优化后的界面代码:
<!DOCTYPE html>
<html>
<head>
<title>Login</title>
<script src="https://cdn.bootcdn.net/ajax/libs/jquery/3.6.0/jquery.min.js"></script>
<style>
form {
display: flex;
flex-direction: column;
align-items: center;
margin-top: 20px;
}
label {
font-size: 18px;
margin-bottom: 5px;
}
input[type=text], input[type=password] {
padding: 10px;
border-radius: 5px;
border: none;
margin-bottom: 20px;
width: 300px;
}
input[type=button] {
background-color: #4CAF50;
color: white;
border: none;
border-radius: 5px;
padding: 10px 20px;
cursor: pointer;
font-size: 18px;
margin-bottom: 20px;
width: 300px;
}
input[type=button]:hover {
background-color: #3e8e41;
}
h1 {
text-align: center;
margin-top: 50px;
font-size: 36px;
}
</style>
</head>
<body>
<h1>Login</h1>
<form>
<label for="username">Username:</label>
<input type="text" id="username" name="username">
<label for="password">Password:</label>
<input type="password" id="password" name="password">
<input type="button" id="submit" value="Submit">
</form>
<script>
$(document).ready(function() {
$("#submit").click(function() {
var username = $("#username").val();
var password = $("#password").val();
$.ajax({
url: "/login",
type: "POST",
data: {
username: username,
password: password },
success: function(response) {
if (response == "success") {
window.location.href = "/dashboard";
} else {
alert("Invalid username or password.");
}
},
error: function() {
alert("Error occurred.");
}
});
});
});
</script>
</body>
</html>
这个优化后的界面代码做了以下改进:
1. 使用 CSS 来美化界面,让它更加美观、易于使用和可读性更高。
2. 将表单元素布局在一个垂直方向上,使界面更加整洁。
3. 对表单元素的大小、间距和样式进行微调,使它们更加一致和易于使用。
4. 将 JavaScript 代码移到一个单独的 <script> 标签中,使它更加易于维护和重用。
