Even so… fantastic short article!
The reason I mostly dislike this in all probability emanates from my bias of getting labored on the web page using it, that I didn’t originally style.
You set the same track record-image on numerous CSS classes and set the background position and Proportions of the person courses to Show just one portion of the sprite. Here’s some code that demonstrates the idea:
We wish to changeover in the beginning history-position of 0px to shifting the placement remaining by full width in the sprite sheet image file (8640px, and that is each 1440px width image multiplied by six since you will here find six frames). This can be the code:
