Hamburger Styling

Hi everyone! I need to make my hamburger button change while menu is opened.
I’ve already create Div with 2 div that are lines. Now i need to make it change.

Thanks for you tips!
There is a screenshot of what should be made.

Hey Joanna24,

Here’s a small video I made explaining how you can achieve this. Ignore the starting 30 seconds, was just trying to figure out :stuck_out_tongue:

that is very useful, but I need that hamburger always be with linger line when menu is open. is there any hint? may be just change animation or its uration?
