Detailed explanation of how to create shadow effects in css3 [code example]

Let’s introduce it in detail by combining pictures and code. demo1 shows the normal div block shadow effect. I believe everyone has noticed the box-shadow attribute. . boxshadow means box shadow. That is to say, in CSS3 we can achieve different shadow effects by controlling the value of box-shadow. In 1, the value of box-shadow is 5px 5px 5px black; they represent the horizontal x-axis offset, vertical y-axis offset, blur radius and shadow color respectively.

The values of box-shadow in demo2 are 5px 5px 5px 5px black; here they represent the amount of horizontal offset of the x-axis, the amount of vertical offset of the y-axis, the blur radius, the shadow radius and the shadow color. . The shadow radius here is a positive value!

The values of box-shadow in demo3 are 8px 8px 8px -8px black; the shadow radius here is a negative value!

The values of box-shadow in demo4 are 5px 0px 5px -5px black, -5px 0px 5px -5px black; the effect here is a bilateral shadow effect.

The values of box-shadow in demo5 are 8px 0px 8px -8px black; what is shown here is the single-sided shadow effect.

If we set the blur radius to 0, there will be no blurring effect, and the larger the value, the more blurry it will be. If we set the shadow radius value to be positive, the entire shadow will expand, and if the value is negative, it will shrink.

The above is an introduction to the specific use of boxshadow in CSS3, that is, how to use the boxshadow attribute to set various shadow effects. For example, if you want no shadow on the left side of boxshadow, single-sided shadow of boxshadow, shadow around boxshadow, etc., you can achieve this effect.
