Question

I tried to change the HTML form, input type file. Here is my code:

HTML, form id = form

<input class="upload_file" type="file" id="file" name="file" />

.CSS

I tried both:
.upload_button{
  background: url('../images/upload_btn_bg.png') no-repeat;
  width: 200px; 
  height: 40px;
}

#form input[type=file]{
  background: url('../images/upload_btn_bg.png') no-repeat;
  width: 200px; 
  height: 40px;
}

None of both of those methods works. I did see from some website, like facebook, youtube, google or twitter, they have different style. Wonder how they do it.

Answer 1

You can’t do anything with input type file (other than huge hacks). I know this sounds horrible, but the web standards still haven’t come up with a solution for that.

What I would suggest though, is that you used something more flexible, such as swfUpload, which let’s you change stiles, and also check for file size prior to uploading.

Some neat examples of it can be found here

Hope this helps you
