File input field inside button doesn't work in Firefox

Question

I\'d like to have a styled file input field on my page and therefore put it inside a button which it completely covers and made it invisible by set

Answer 1

According to W3 specification of the BUTTON tag, you cannot inset the following tags inside a tag:

• A
• INPUT
• SELECT
• TEXTAREA
• LABEL
• BUTTON
• FIELDSET

However, all the other block and inline tags are allowed.
