Style code: 1. Text shadow style "text-shadow: h-shadow v-shadow blur color;"; 2. Border shadow style "box-shadow: h-shadow v-shadow blur spread color inset ;"; 3. Picture shadow style "filter:drop-shadow(h-shadow v-shadow blur spread color);".
The operating environment of this tutorial: Windows 7 system, CSS3&&HTML5 version, Dell G3 computer.
In HTML, there are three ways to add shadow styles to elements:
Text shadow: use the text-shadow attribute
Border shadow: use the box-shadow attribute
Picture shadow: use the filter attribute (needs to be used with the drop-shadow() function)
1. Text shadow style
In HTML, you can use the text-shadow attribute to implement shadowed text. The text-shadow attribute is applied to shadow text. .
Syntax
text-shadow: h-shadow v-shadow blur color;
Value | Description |
---|---|
h-shadow | Required. The position of the horizontal shadow. Negative values are allowed. |
v-shadow | Required. The position of the vertical shadow. Negative values are allowed. |
blur | Optional. Blurred distance. |
color | Optional. The color of the shadow. |
Note: The text-shadow property connects one or more shadow text. The property is a shadow, specifying every 2 or 3 length values and an optional color value separated by commas. The expired length is 0.

2. Border shadow style
In html, you can use the box-shadow attribute to implement a border with a shadow style. The box-shadow property can set one or more drop-down shadow boxes.
Syntax
box-shadow: h-shadow v-shadow blur spread color inset;
Value | Description |
---|---|
h-shadow | Required. The position of the horizontal shadow. Negative values allowed |
v-shadow | Required. The position of the vertical shadow. Negative values allowed |
blur | Optional. Fuzzy distance |
#spread | Optional. The size of the shadow |
#color | is optional. The color of the shadow. |
inset | Optional. Change shadow to inner shadow from outer shadow (at start) |
注意:boxShadow 属性把一个或多个下拉阴影添加到框上。该属性是一个用逗号分隔阴影的列表,每个阴影由 2-4 个长度值、一个可选的颜色值和一个可选的 inset 关键字来规定。省略长度的值是 0。

3、图片阴影样式
在html中,可使用filter属性来实现带阴影样式的边框。
filter 属性定义了元素(通常是)的可视效果,当和drop-shadow()函数一起使用,可给图像设置一个阴影效果。
filter:drop-shadow(h-shadow v-shadow blur spread color);
阴影是合成在图像下面,可以有模糊度的,可以以特定颜色画出的遮罩图的偏移版本。 函数接受
h-shadow v-shadow (必须)
这是设置阴影偏移量的两个
如果两个值都是0, 则阴影出现在元素正后面 (如果设置了
这是第三个code>
这是第四个
注意: Webkit, 以及一些其他浏览器 不支持第四个长度,如果加了也不会渲染。
