When we browse major websites, clicking on the pictures may cause special effects such as enlargement or rotation. This effect can indeed make people’s eyes brighter, and it may also bring traffic to users’ clicks. Of course, the powerful CSS functions are not limited to such special effects. This article will introduce to you a more cool special effect, which is the css shadow effect produced when the mouse moves into the div block, so that it can immediately create a three-dimensional effect.

The specific code example of css shadow effect is as follows:

  <style>
        .shadow{
            float:left;
            margin-left:20px;
            background: #EEFF99;
            width:200px;
            height:400px;
        }
        .shadow:hover{
            -webkit-box-shadow: #ccc 0px 10px 10px;
            -moz-box-shadow: #ccc 0px 10px 10px;
            box-shadow: #ccc 0px 10px 10px;  }
    </style>

Note: Whether you add a shadow to that element, you cannot do without an important attribute: the hover pseudo-class.

:hover pseudo-class is to add a special style to this element when the mouse moves over it. As long as you master the use of this hover, you can easily achieve this effect whether you are adding shadows to div blocks or pictures.

This pseudo-class is used to apply elements in a "hover state". Hover is defined as when the user indicates an element but does not activate it. The most common example of this is moving the mouse pointer within the bounds of a hyperlink in an HTML document. In theory, other elements could be hovered, but CSS doesn't define which ones.
