Animation in css

Navigation
0

I have a code in html that when I click the button it opens a modal, and within the modal I have another button to close, and I would like to put an animation in the open time and at the closing time, for example it fading or something like that.

javascript 

function openModal(){
        var i = document.getElementById('i').value;
        if (i == '0') {
            document.getElementById('i').value = '1';
            document.getElementById('modal').style = 'display: flex;';
        }else{
            document.getElementById('i').value = '0';
            document.getElementById('modal').style = 'display: none;';
        }
    }

CSS 

*{margin: 0;}
    .btn {
        background: #3498db;
        background-image: -webkit-linear-gradient(top, #3498db, #2980b9);
        background-image: -moz-linear-gradient(top, #3498db, #2980b9);

Just add these properties in .modal css 

animation-duration: 3s;
animation-name: slidein;
animation-directioniteration-count: infinite;

and add the following animation in css 

@keyframes slidein {
        from {
            margin-left: 100%;
            width: 300%; 
        }

        to {
            margin-left: 0%;
            width: 100%;
        }
    }

Thank you very much.
