Animated Modal Box

Raktim · November 19, 2019

I create a modal box that when the user clicks on the button the modal will appear with animation.

When the user clicks on the close button ( located on the right side of the header area ) or anywhere of the screen except modal box it will disappear without animation.

I want that the modal will disappear/hide with animation.

I create two CSS animation. One is animatetop which I already used when modal will open and another is animatedown which I want to use when modal will disappear. But, I can't understand how to do that?

See the code on JSFiddle

        .background{
            display:none;
            position: fixed;

            left: 0;
            top: 0;

Thanks for helped me. I need some time to understand the code. Because I am a JS beginner, not JQuery...
