background attribute in CSS

Question

background:#777777 none repeat scroll 0 0;

the 5 attributes it includes are background-color,background-image,background-repeat,background-attachment and background-position.

My question is:

Are background-repeat,background-attachment and background-position useless if background-image is none? Because according to the document,these are all used to change background-image.

Answer 1

yes. They have no meaning without that.

Answer 2

You can simply write

background:#777777;

or,

background-color:#777777;

All of those attributes affect the image only.

In general, if a CSS attribute sets multiple values (eg, background, border, font), you don't need to specify all of the values; any values you don't specify will be left at their defaults.

Answer 3

IF you just want a background color, consider using the background-color attribute instead of background.
