function generateName(){
	let firstname = ["Kai", "Eliana", "Jaden", "Ezra", "Luca", "Rowan", "Nova", "Amara", "Aaliyah", "Finn"];
	let lastname= ["Smith", "Johnson", "Williams", "Brown", "Jones", "Garcia", "Miller", "Davis", "Martinez", "Wilson"];
	let rand_first = Math.floor(Math.random()*firstname.length); 
	let rand_last = Math.floor(Math.random()*lastname.length); 
	let result=document.getElementById('result');
	result.removeAttribute('style');
	result.innerHTML= "<div class='alert alert-success' style='height:120px; padding:20px;'><center><h2>"+firstname[rand_first]+" "+lastname[rand_last]+"</h2></center></div>";
 
}
