Login form

Hi developers, 

 

I’m new on skinning. 

I’m designing my skin but I have a problem with login page

I want to add a form which opens when user click on “SIGN-IN” with fade action on current page to login

 

May help me please to create this form? 

I dont know anything about this and dont know where I can edit the login page template. So decided to create this flash form to open at the current page where user on it
