Example of implementing shadow effect using css3

CSS3 is an upgraded version of CSS technology, and CSS3 language development is developing towards modularity. The previous specification was too large and complex as a module, so it was broken down into smaller modules and more new modules were added. These modules include: box model, list module, hyperlink method, language module, background and border, text effects, multi-column layout, etc. In this chapter, we will tell you a simple CSS3 shadow effect example. You can use the shadow property of CSS3 to add a shadow effect to elements of a web page. This is a new feature. However, this feature only works on browsers that support CSS3, such as Firefox 3.5, Safari 3.1 +, and Google Chrome.

Let’s talk about how to use the shadow attribute of css3.

css3 shadow mainly uses the box-shadow attribute. The syntax format of this attribute is as follows:

box-shadow:

The above attribute values have the following meanings:

horizontal (horizontal): Specify the horizontal offset shadow. Positive values (ie: 5px) will shift the shadow to the right, while negative values (ie: - 10px) will bias it to the left.
vertical: Specifies a vertical offset shadow. Positive values (ie: - 5px) will make the shadow at the bottom of the box, while negative values (ie: - 10px) will bias it upwards.
blur (blur): Set the softening radius. The default value is 0, which means no blur. Positive values increase blur, while negative values actually shrink shadows. This property defaults to 0.
clolor (color): color value, that is, setting the shadow color.

Reminder: This attribute can be added to any element, such as pictures, Div, SPAN, P tags, etc.
