Polyfills are used to patch browser incompatibilities and inconsistencies. Wee ships with a couple basic components. If you don’t need them just remove them from the IE10 compile array.
The Wee placeholder polyfill patches support for the placeholder attribute on inputs and textareas. It sets the value to the placeholder but clears it on focus and form post to mimic native placeholder functionality.
<input type="text" name="title" placeholder="Entry Title"> <textarea name="message" placeholder="Write your message..."></textarea>
