Hi,
I’m creating a website with hamburger menu. Clicking on the hamburger menu icon the modal opens or closes (toggles).
When the menu is closed I have the classic 3 stripes icon. I want to change that icon to a cross when the menu is opened.
I can set a second icon (with the cross) besides the menu icon and set it invisible. But I don’t know how to set it visible on clicking on the menu icon ( and make the menu icon invisible).
