This article mainly introduces the use of CSS3 layer shadows and text shadows. It has a certain reference value. Now I share it with you. Friends in need can refer to

box-shadow layer The shadow attribute and the text-shadow text shadow attribute are similar in usage. They both use the X-axis and Y-axis coordinate systems to control the shadow expansion. Here we will explain in detail the use of CSS3 layer shadow and text shadow effects:

box-shadow layer shadow

box-shadow: Shadow type X horizontal offset (can take positive and negative values) Y vertical offset (can take positive and negative values) Shadow size shadow extended shadow color value
The shadow type can be omitted, the default is outer shadow, when its value is inset, it is inner shadow effect.
X horizontal offset and Y vertical offset can take positive and negative values. When X is negative, it is projected on the left, and when it is positive, it is projected on the right. When Y is negative, it is projected on top, when it is positive, it is projected on the bottom.
The shadow size and expansion are the same as in ps.

Browser compatibility:
Different browsers have different compatibility. The mozilla kernel browser is written as follows (but the new version of Firefox does not need to be added):
-moz-box-shadow: Shadow type
-webkit-box-shadow:Shadow type :

<p class="shadow"></p>   
.shadow{   
 width:200px;   
 height:50px;   
 box-shadow:3px 3px 3px 3px #000;   
 /*-moz-box-shadow:3px 3px 3px 3px #000;    //以火狐为代表的mozilla内核浏览器，火狐现在的版本已经支持这个属性，所以不用再加-moz*/
 -webkit-box-shadow:3px 3px 3px 3px #000;   
}
