The only software required is the user's browser. Moreover, unlike pre-set image effects, CSS filter effects are responsive and animatable.

The only software required is the user's browser. Moreover, unlike pre-set image effects, CSS filter effects are responsive and animatable.
 
 The CSS filter effects module provides the {{cssxref("filter")}} and {{cssxref("backdrop-filter")}} properties that you can use to impact the rendering of text, images, backgrounds, and borders, or any element on which you apply these properties. This module also defines the {{cssxref("<filter-function>")}} data type that lets you add graphical effects such as blurring or color shifting. Using the filter functions, you can not only alter the appearance of an element but also reference an SVG filter using a filter that you create.
