How Can I Customize the File Input Element's Appearance and Functionality?

Customizing File Input Element Type

This question centers around the customization of the file input element type, specifically to implement a background image, round border, and potential button styling.

To achieve this without browser compatibility concerns, follow the provided steps:

1. HTML Form:

   • Create an HTML form with a "Click to upload" button (element with id="yourBtn") and a hidden file input (element with id="upfile", hidden by styling).

2. JavaScript Function:

   • Add a JavaScript function (getFile()) to trigger the hidden file input when the "Click to upload" button is clicked.

This approach allows for unrestricted styling of the input element without worrying about browser-specific nuances.

Additionally, to simplify the process further, here's a complete example with automated file upload:

HTML:

<style>
#yourBtn {
  position: relative;
  ...
}
</style>
<form action="#" method="POST" enctype="multipart/form-data" name="myForm">
  <div>

JavaScript:

function getFile() {
  document.getElementById("upfile").click();
}
function sub(obj) {
  var file = obj.value;
  var fileName = file.split("\");
  document.getElementById("yourBtn").innerHTML = fileName[fileName.length - 1];
  document.myForm.submit();
  event.preventDefault();
}

This code combines the button styling and click event handling with automatic file upload by submitting the form when the input changes.
