 ## Parallel animation using group() function
 
-You've seen how to add a delay between each successive animation. But you may also want to configure animations that happen in parallel. For example, you may want to animate two CSS properties of the same element but use a different `easing` function for each one. For this, you can use the animation `group()` function.

 ## Sequential vs. parallel animations
 
-Complex animations can have many things happening at once. But what if you want to create an animation involving several animations happening one after the other? Earlier we used `group()` to run multiple animations all at the same time, in parallel.

 A second function called `sequence()` lets you run those same animations one after the other. Within `sequence()`, the animation steps consist of either `style()` or `animate()` function calls.

-Angular functions for animating multiple elements start with `query()` to find inner elements, for example gathering all images within a `<div>`. The remaining functions, `stagger()`, `group()`, and `sequence()`, apply cascades or allow you to control how multiple animation steps are applied.
