Each of the approaches you list has benefits and drawbacks, so it’s impossible to answer which is the “preferred way.” Likewise, many of these examples will return immediately because they use deferred execution, so they’ll technically run faster, but won’t actually make your program run any faster. But if you’re … Read more

background: #ffff url(image) no-repeat top left is actually short for background-color: #fff; background-image: url(image); background-repeat: no-repeat; background-position: top left; Setting the background-size property to cover makes background-repeat obsolete.

As Zuber suggested, just write the long hand properties. body { background-image: … Read more
