I am creating web application with facebook login. And i have a problem with stylizing login button. The default facebook login button is inside iframe and my css styles doesn't aply to this element. I tried also to use jquery .click() function to trigger hidden button but it doesn't work too.
this is default facebook button:

and this is the final effect what I want to achieve:

this button is already in my html, it looks great but it doesn't work because default button must be clicked. My question are:
1)Is there any way to stylize facebook login button?
2)How to trigger working click event on facebook button using jquery?
