const box = document.getElementById("box");
const upBtn = document.getElementById("btn1");
const downBtn = document.getElementById("btn2");

var pos;

window.onload = function(){
upBtn.onclick = moveUp;
downBtn.onclick = moveDown;
box.style.top = "150px";
pos = 150;
ChkPos();
}

function moveUp(){
pos-=50;
if (pos<=0) pos=0;
box.style.top = pos+"px";
ChkPos();
}

function moveDown(){
pos+=50;
if (pos>=300) pos=300;
box.style.top = pos+"px";
ChkPos();
}

ChkPos = () => {
upBtn.disabled = pos<=0;
downBtn.disabled = pos>=300;
}
