Creates an animated underline effect when the user hovers over the text.

- Use `display: inline-block` to make the underline span just the width of the text content.
- Use the `::after` pseudo-element with `width: 100%` and `position: absolute` to place it below the content.
- Use `transform: scaleX(0)` to initially hide the pseudo-element.
- Use the `:hover` pseudo-class selector to apply `transform: scaleX(1)` and display the pseudo-element on hover.
- Animate `transform` using `transform-origin: left` and an appropriate `transition`.
- Remove the `transform-origin` property to make the transform originate from the center of the element.

```html
<p class="hover-underline-animation">Hover this text to see the effect!</p>
```

```css
.hover-underline-animation {
  display: inline-block;
  position: relative;
  color: #0087ca;
}

.hover-underline-animation::after {
  content: '';
  position: absolute;
  width: 100%;
  transform: scaleX(0);
  height: 2px;
  bottom: 0;
  left: 0;
  background-color: #0087ca;
  transform-origin: bottom right;
  transition: transform 0.25s ease-out;
}

.hover-underline-animation:hover::after {
  transform: scaleX(1);
  transform-origin: bottom left;
}
```
