Here is the code snippet that I am working with:
document.getElementById('showRtb').addEventListener('click', function () {
document.getElementById('rtb').style.display="inline-table";
});
document.getElementById('hideRtb').addEventListener('click', function () {
document.getElementById('rtb').style.display="none";
});
I am now looking to achieve a FadeIn animation effect using just JavaScript, without relying on jQuery or CSS3. Is such a task achievable?
