 Creates a pulse effect loader animation using the `animation-delay` property.
 
-- Use `@keyframes` to define an animation at two points in the cycle: at the start (`0%`), the two `<div>` elements have no `width` or `height` and are positioned at the center and at the end (`100%`), both `<div>` elements have increased `width` and `height`, but their `position` is reset to `0`.
+- Use `@keyframes` to define an animation at two points in the cycle. At the start (`0%`), the two `<div>` elements have no `width` or `height` and are positioned at the center. At the end (`100%`), both `<div>` elements have increased `width` and `height`, but their `position` is reset to `0`.
 - Use `opacity` to transition from `1` to `0` when animating to give the `<div>` elements a disappearing effect as they expand.
 - Set a predefined `width` and `height` for the parent container, `.ripple-loader` and use `position: relative` to position its children.
 - Use `animation-delay` on the second `<div>` element, so that each element starts its animation at a different time.
