Ease text effect

Hey check out the example pls…

now how can i make that instead of the hole text and grey bar resize with ease, to only resize the grey bar…
thanks,

so you u just want the grey box to resize when you mouse over it? & No text to display at all, is that right?

no, snaxs is a button and when you roll over i want the bar to grow to the rigth… with ease and when you rollout to go back to the original form
