Give the list element a max-height of 0px so that it is not visible by default. If the animation duration is 300ms and there are 5 items overall, then we can delay each item by 60ms increments: (num * 60ms). The breakdown of the steps we will be doing is as follows: Create a simple navbar with an element that pops down some content as dropdown Create an element containing the dropdown content below the dropdown-trigger element created in the first step. Finally, we can use the num variable to delay each item by an even amount.

We could manually write a CSS selector for each dropdown menu item with a different animation-delay or we can take advantage of Stylus's for loop to iterate over each and generate those selectors automatically. The only property that needs to be different is the animation-delay to stagger each item's animation. Fortunately, all menu items will share the same rule, same duration, same timing function, same animation-fill-mode, and same transform-origin property. dropdown_menu is the actual menu itself, which is by default hidden.Īnimating the whole menu meant we only needed to add an animation for each menu, but animating each menu item individually means we need to add a separate animation property for each menu item. The structure is the same for all menus: dropdown is the container for the menu title and the hidden menu. While animations can add some fun visual flair, keep in mind these examples are slightly exaggerated to make the mechanics of the animation more obvious. The CSS syntax is Stylus, which is a similar to SASS. Below are five animations using CSS transforms for both the whole menu and each item individually.
