Throughout various examples, jQuery plugins, and CSS-styled HTMLElements, I have observed the setting of icons on an image with multiple options.
I am eager to implement this practice in my own apps.

For instance, in the mentioned image, how can one choose a specific icon using CSS? What is the proper method for selecting one of them?
Are there any sample implementations available?
Thank you!
The key to using CSS for displaying images lies in manipulating their positioning and clipping within a parent element, whether by setting them as backgrounds or absolute positioned images with overflow: hidden.
Take this HTML for example:
<div class="sprite-images checkbox"></div>
Let's say the checkbox image we want is located at (32, 32) on the spritesheet, with dimensions of 32x32px.
Your CSS code would then resemble this:
.sprite-images{
width: 32px;
height: 32px;
display: block; // can't be inline
}
.sprite-images.checkbox{
background-image: url("images/my_spritesheet.png"); // specify sprite sheet URL
background-position: 32px 32px; // coordinates for the desired icon
}
It's that straightforward. The background-image will automatically be clipped by the div according to its set size, translating it so only your intended sprite is visible.
