Example

<om-starry-sky
  [skyColor]="'#000022'"
  [starsBackgroundConfig]="{
    starDensity: 0.00025,
    twinkleProbability: 0.9,
    minTwinkleSpeed: 0.3,
    maxTwinkleSpeed: 0.7
  }"
  [shootingStarsConfig]="{
    minSpeed: 20,
    maxSpeed: 40,
    starColor: '#FFD700',
    trailColor: '#FF4500'
  }"
  styleClass="starry-sky-custom"
>
  <div class="content">Magical Night Sky</div>
</om-starry-sky>

This example creates a starry sky with higher star density, frequent twinkling, and golden shooting stars with a fiery trail.

Styling

To further customize the appearance of the starry sky or container, use the styleClass input to apply your own CSS classes.

.starry-sky-custom {
  position: relative;
  height: 100vh;
  background-color: #000022;
}

.content {
  position: relative;
  z-index: 1;
  color: white;
  text-align: center;
  padding-top: 50px;
}

This will create a fullscreen starry sky with custom content displayed on top.
