Stylinde the Calendr with CSS
Clean, responsive CSE transforms tth setting HTML ino a usable interface.
.calendar-grid {

Core Javascott: Generating the Calendr Grid
All dynamic rendering live dan Javasclan.
Workingwith the Date Object
Te 1f calendar logic.
Building the Grid
function renderCalendar() {
const grid = document.querySelector('.calendar-grid');
grid.innerHTML = '';
const firstDay = new Date(currentYear, currentMonth, 1).getDay();
const daysInMonth = new Date(currentYear, currentMonth + 1, 0).getDate();
// Add empty cells for days before the 1st
for (let i = 0; i < firstDay; i++) {
const empty = document.createElement('div');
empty.className = 'day-cell empty';
grid.appendChild(empty);
}
// Generate day cells
for (let day = 1; day <= daysInMonth; day++) {
const cell = document.createElement('div');
cell.className = 'day-cell';
cell.dataset.date = `${currentYear}-${currentMonth + 1}-${day}`;
const dateSpan = document.createElement('span');
dateSpan.textContent = day;
cell.appendChild(dateSpan);
// Highlight today
const today = new Date();
if (currentYear === today.getFullYear() && currentMonth === today.getMonth() && day === today.getDate()) {
cell.classList.add('today');
}
// Load events for this date
loadEvents(cell);
grid.appendChild(cell);
}
}
