In CSS3, you can use the "box-shadow" attribute to cancel the shadow on the border. This attribute is used to set one or more drop-down shadow boxes. Just set the value of this attribute to "none". You can cancel the border shadow of the element. The syntax is "element {box-shadow: none;}".

The box-shadow property can set one or more drop-down shadow boxes.
