-moz-linear-gradient

Could someone explain to me what this portion of code means?

repeat scroll 0 0 #F6F6F6;

I have googled a lot and only found开发者_高级运维 syntax to this part

-moz-linear-gradient(center top , #FFFFFF, #EFEFEF)

My code:

background: -moz-linear-gradient(center top , #FFFFFF, #EFEFEF) repeat scroll 0 0 #F6F6F6;

Thanks!

These are actually part of the background CSS property, not -moz-linear-gradient. Have a look at that link, it should explain.

Basically:

• repeat: The background repeats!
• scroll: When the page scrolls, the background scrolls too
• 0 0: Says, "start the background from this point in the image".

All the extra stuff is probably unneccessary - they seem to be the same as the defaults.

background: <image> <repetition> [scroll] <pos-x> <pos-y> <color>;

• image can be both an image url() or in some browsers, a gradient object.
• repetition can be no-repeat, repeat-x, repeat-y or repeat (both) and means how to repeat the image if it doesn't fill the background.
• if scroll is set, the background will stay fixed on the screen and not follow the text when you scroll.
• pos-x and pos-y determines the offset of the background.
• color means the color that used if the image value was invalid.

Those are additional options to the background: css shorthand.

The repeat repeats the image (although, -moz-linear-gradient doesn't support repeating).

scroll (as opposed to fixed) allows the background to "scroll"

0 0 are x and y coords for the placement of the top left corner of the image.

#F6F6F6 is a background color
