【CSS练习】万年历 html+css+js

万年历是一个常见的前端开发项目，以下是一个简单的实现方式：

HTML:




<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Simple Calendar</title>
<style>
    .calendar {
        font-family: Arial, sans-serif;
        -webkit-font-smoothing: antialiased;
        -moz-osx-font-smoothing: grayscale;
        border-collapse: collapse;
        width: 100%;
    }
    .calendar th, .calendar td {
        border: 1px solid #ddd;
        padding: 8px;
        text-align: left;
    }
    .calendar th {
        background-color: #f2f2f2;
    }
</style>
</head>
<body>
 
<table class="calendar">
    <thead>
        <tr>
            <th>Sun</th>
            <th>Mon</th>
            <th>Tue</th>
            <th>Wed</th>
            <th>Thu</th>
            <th>Fri</th>
            <th>Sat</th>
        </tr>
    </thead>
    <tbody>
        <!-- JavaScript will populate this part -->
    </tbody>
</table>
 
<script>
// JavaScript code to populate the calendar goes here
</script>
 
</body>
</html>

CSS:




/* Same as the CSS provided in the question */

JavaScript:




function getDaysInMonth(year, month) {
    return new Date(year, month, 0).getDate();
}
 
function getStartingDay(year, month) {
    return new Date(Date.UTC(year, month - 1, 1)).getDay();
}
 
function createCalendar(year, month) {
    const daysInMonth = getDaysInMonth(year, month);
    const startingDay = getStartingDay(year, month);
  
    const tbody = document.querySelector('.calendar tbody');
    let tr, td;
  
    // Clear any existing rows
    tbody.innerHTML = '';
  
    // Create the first row with the days of the week
    tr = document.createElement('tr');
    for (let i = 0; i < 7; i++) {
        td = document.createElement('td');
        td.textContent = ['Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat'][i];
        tr.appendChild(td);
    }
    tbody.appendChild(tr);
  
    // Create the rest of the rows for the month
    for (let i = 0; i < (startingDay + daysInMonth); i++) {
        if (i % 7 === 0) {
            tr = document.createElement('tr');
        }
  
        td = document.createElement('td');
