How Can I Customize File Input Appearance with CSS3 and JavaScript?

Styling Input Files with CSS3 and JavaScript

While it's possible to style the default "input file" element using CSS3, the customization options are limited. To fully customize the appearance of the file input or trigger the browsing window with an alternative element, here's how you can achieve it using HTML, CSS3, and JavaScript:

Customizing with jQuery

1. HTML: Insert both the default file input and a div element that will serve as the custom button.

<div>

2. CSS: Hide the default file input.

#file {
    display: none;
}

3. jQuery: Wrap the file input in a div with hidden dimensions to prevent accidental clicks. Use the change event to update the custom button text with the selected file path. Trigger the file input click event when the custom button is clicked.

var wrapper = $('<div/>').css({height: 0, width: 0, 'overflow': 'hidden'});
var fileInput = $(':file').wrap(wrapper);

fileInput.change(function() {
    $(this).closest('#file').text($(this).val());
});

$('#file').click(function() {
    fileInput.click();
}).show();

Result:

A custom file input element that can be customized through CSS and triggers the file browsing window when clicked.
