Countdown Timer
To customize the countdown timer, simply change the countdownDate and countdownTime variables to the desired date and time in the format "YYYY-MM-DD" and "HH:MM:SS" respectively. You can also change the font size and color in the CSS style.
// Function to change the font family
function changeFont() {
var fontSelector = document.getElementById("font-selector");
var font = fontSelector.options[fontSelector.selectedIndex].value;
document.getElementById("countdown").style.fontFamily = font;
}
