What is the difference between background and background color

In CSS, background and background-color are two distinct properties with different purposes.

The background-color property is used to set the background color of an element. It accepts various color values, such as color keywords, hexadecimal codes, RGB or RGBA values, HSL or HSLA values, etc. For example:

css
div {
  background-color: #ff0000; /* Sets background color to red */
}

On the other hand, background is a shorthand property that allows you to set multiple background-related properties simultaneously, including background-color, background-image, background-repeat, background-position, and background-size. Using the background property enables you to define all these properties in a single declaration. For example:

css
div {
  background: #ff0000 url('image.jpg') no-repeat center center / cover;
}

In the above example, #ff0000 sets the background color, url('image.jpg') sets the background image, no-repeat specifies that the image should not repeat, center center sets the image position, and / cover specifies that the background image should cover the entire element area.

Using the background property is a shorthand method that reduces code redundancy and provides clearer code. However, when you only need to set the background color, using background-color is more direct and straightforward. Additionally, if you want to modify a specific background property without affecting others, using individual properties like background-color or background-image is more appropriate.

The background property replaces all previous individual properties such as background-color and background-image. It is essentially a shorthand property but also acts as a reset.

I sometimes use it to override previous specifications when customizing the background. I need the following:

background: white url(images/image1.jpg) top left repeat;

as follows:

background: black;

Therefore, all parameters (background-image, background-position, background-repeat) are reset to their default values.

Assuming these are treated as separate properties, in your specific example, there is no difference in the outcome because background is actually a shorthand that includes:

shell
background-color
background-image
background-position
background-repeat
background-attachment
background-clip
background-origin
background-size

Therefore, besides background-color, you can use the background shorthand to add one or more values without repeating other background-* properties multiple times.

Which one you choose largely depends on your preference, but it may also depend on specific conditions of the style declaration (for example, if you need to override when inheriting other related background-* properties from the parent background-color, or if you need to remove all values except background-color).
