Background, background-color, background-image difference

answer I got from bing chat:

    • background-color: This property sets the background color of an element. It can take a color value such as a name, a hex code, an RGB value, etc. For example: background-color: blue;
  • background-image: This property sets one or more background images for an element. It can take a URL value that points to an image file, or a gradient value that creates a color transition. For example: background-image: url("flower.jpg"); or background-image: linear-gradient(to right, red, yellow);
  • background: This property is a shorthand that combines multiple background properties in one declaration. It can take values for background-color, background-image, background-repeat, background-position, background-size, background-attachment, and background-origin. For example: background: pink url("star.png") no-repeat center;*

my conclusion:
*it might be better just to only use ‘background:’ altogether because it does what ‘background-color’ and ‘background-image’ would do anyways. *

?

I think it just depends on the situation.

There are times where all you need is a background image and there are times where you just need a background color.

Then there are times where you will need positioning, size, color, etc. and the background shorthand is a good choice.

It always boils down to a case by case basis

Something to be aware of when using the shorthand property is that it will reset other properties. Any property not set when using the shorthand will be set to the default values.

body {
  background-image: url("https://plus.unsplash.com/premium_photo-1669731124128-b4ff5cc94881?ixlib=rb-4.0.3&ixid=MnwxMjA3fDB8MHxwaG90by1wYWdlfHx8fGVufDB8fHx8&auto=format&fit=crop&w=1200&q=80");
  background-repeat: no-repeat;
  background-size: cover;
  background-attachment: fixed;
}

@media (max-width: 800px) {
  /* resets the other background properties */
  body {
    background: url("https://plus.unsplash.com/premium_photo-1675453018387-a910e9db0846?ixlib=rb-4.0.3&ixid=MnwxMjA3fDB8MHxwaG90by1wYWdlfHx8fGVufDB8fHx8&auto=format&fit=crop&w=600&q=80");
  }
}

For this reason, it is usually not a good idea to set single properties using the shorthand.

It can also get harder to read if a lot of properties are set using the shorthand.
