Custom File Upload Button With Image Preview

Mohammad Azad Verified
Here is how I created a custom file upload button.
var fileInput = document.getElementById('fileInput');
        var deleteImage = document.getElementById('deleteImage');
        var previewImage = document.getElementById('previewImage');
        var fileName = document.getElementById('fileName');

        // image preview
        function fileUpload() {
            //it will show image path
            let text = fileInput.value;
            fileName.innerHTML = text;

            //show the image
   = 'flex';

        // delete image
        deleteImage.addEventListener('click', function () {
            fileInput.value = null;
   = "none";
            font-family: 'Roboto', sans-serif;
        .file-upload {
            max-width: 300px;
            background-color: #f8fafd;
            border: 2px dashed rgba(231,234,243,.7);
            padding: 60px;
            border-radius: 12px;
            margin: 60px auto;
        .file-upload .input-group{
            text-align: center;
        .file-upload .input-group input[type="file"]{
