Box-shadow layer Shadows

Box-shadow: Shadow type x horizontal offset (preferably positive or negative) Y vertical offset (preferably positive or negative) shadow size shadow Extended Shadow color value
The shadow type can be omitted, and the default is an outer projection, which is an inner shadow effect when its value is inset.
The x horizontal offset and y vertical offset are positive negative values, and when x is negative, it is projected on the left, and the projection is on the right. When Y is negative, it is projected on the top, and is projected below.
The size and extension of the shadow is the same as the principle inside PS.

Different browser compatibility, Mozilla Kernel browser is written as follows (but the new version of Firefox has no need to add):
-moz-box-shadow: Shadow type x horizontal offset (preferably positive or negative) Y vertical offset (preferably positive or negative) shadow size shadow Extended Shadow color value
The browser of the WebKit kernel is written as follows:
-webkit-box-shadow: Shadow type x horizontal offset (preferably positive or negative) Y vertical offset (preferably positive or negative) shadow size shadow Extended Shadow color value
