制作日历css

基础日历结构

使用HTML创建日历的基本框架，包含月份、星期和日期格子。以下是一个简单的HTML结构示例：

<div class="calendar">
  <div class="header">
    <button class="prev">←</button>
    <h2 class="month-year">January 2023</h2>
    <button class="next">→</button>
  </div>
  <div class="weekdays">
    <div>Sun</div>
    <div>Mon</div>
    <div>Tue</div>
    <div>Wed</div>
    <div>Thu</div>
    <div>Fri</div>
    <div>Sat</div>
  </div>
  <div class="days"></div>
</div>

基础CSS样式

为日历添加基本样式，包括布局、颜色和边框。以下CSS代码可以自定义日历的外观：

.calendar {
  width: 300px;
  border: 1px solid #ddd;
  border-radius: 8px;
  font-family: Arial, sans-serif;
  box-shadow: 0 2px 10px rgba(0,0,0,0.1);
}

.header {
  display: flex;
  justify-content: space-between;
  align-items: center;
  padding: 10px;
  background-color: #4285f4;
  color: white;
  border-radius: 8px 8px 0 0;
}

.header button {
  background: none;
  border: none;
  color: white;
  font-size: 16px;
  cursor: pointer;
}

.weekdays {
  display: grid;
  grid-template-columns: repeat(7, 1fr);
  text-align: center;
  padding: 10px 0;
  background-color: #f5f5f5;
}

.days {
  display: grid;
  grid-template-columns: repeat(7, 1fr);
  gap: 5px;
  padding: 10px;
}

.days div {
  height: 30px;
  display: flex;
  align-items: center;
  justify-content: center;
  cursor: pointer;
}

.days div:hover {
  background-color: #e0e0e0;
}

动态日期填充

使用JavaScript动态填充日期格子，确保正确显示当前月份的日期分布：

const monthYear = document.querySelector('.month-year');
const daysContainer = document.querySelector('.days');
let currentDate = new Date();

function renderCalendar() {
  const year = currentDate.getFullYear();
  const month = currentDate.getMonth();

  monthYear.textContent = 
    new Date(year, month).toLocaleString('default', { month: 'long', year: 'numeric' });

  const firstDay = new Date(year, month, 1).getDay();
  const daysInMonth = new Date(year, month + 1, 0).getDate();

  daysContainer.innerHTML = '';

  for (let i = 0; i < firstDay; i++) {
    daysContainer.innerHTML += '<div></div>';
  }

  for (let i = 1; i <= daysInMonth; i++) {
    daysContainer.innerHTML += `<div>${i}</div>`;
  }
}

document.querySelector('.prev').addEventListener('click', () => {
  currentDate.setMonth(currentDate.getMonth() - 1);
  renderCalendar();
});

document.querySelector('.next').addEventListener('click', () => {
  currentDate.setMonth(currentDate.getMonth() + 1);
  renderCalendar();
});

renderCalendar();

高亮当前日期

在CSS中添加样式以突出显示当前日期：

.current-day {
  background-color: #4285f4;
  color: white;
  border-radius: 50%;
}

在JavaScript中更新renderCalendar函数以标记当前日期：

// 在renderCalendar函数内部添加：
const today = new Date();
if (month === today.getMonth() && year === today.getFullYear()) {
  const dayElements = document.querySelectorAll('.days div');
  dayElements.forEach(day => {
    if (parseInt(day.textContent) === today.getDate()) {
      day.classList.add('current-day');
    }
  });
}

响应式设计

添加媒体查询使日历在不同屏幕尺寸下都能正常显示：

@media (max-width: 400px) {
  .calendar {
    width: 100%;
    border-radius: 0;
  }

  .days div {
    height: 40px;
  }
}

动画效果

为月份切换添加平滑的过渡动画：

.month-year {
  transition: transform 0.3s ease;
}

.header button:active + .month-year {
  transform: scale(1.1);
}
