How Can I Scale CSS Sprites to Half Their Size Using `background-size`?

Scaling CSS Sprites Using background-size

Sprites are a technique used to combine multiple images into a single image, improving website performance. However, when using sprites as background images, you may encounter challenges in scaling them to desired dimensions.

Challenge:

In this specific scenario, the goal is to scale a 100px by 100px sprite to half its size using the background-size property. The current code results in the full-size image being displayed.

Solution:

To overcome this issue, you need to define the dimension of the sprite image. In this case, since the sprite is 500px by 400px, you can reduce it by half by setting the background-size to 250px by 200px. Additionally, adjust the background-position to obtain the desired icon.

Example:

.my-sprite {
  background-image: url("https://i.sstatic.net/lJpW8.png");
  height: 50px;
  width: 50px;
  background-position: 150px 0px;
  background-size: 250px 200px;
  border: 1px solid; /* for testing */
}

<div class="my-sprite"></div>

With these adjustments, the sprite will be scaled down to half its original size, resulting in a 50px by 50px image. The background-position value of 150px 0px ensures that the desired icon is visible within the sprite.
