An Example on CodePen Shows How Animations Can Be Optimized

Animated visual effects on websites were often the domain of JavaScript syntax in web design throughout the 2000s. A layman who might have been recently introduced to web design at the time would likely have described the HTML script as the "standard" script responsible for hosting all the content and structural code responsible for shaping the layout and filling it with content visible on the reader's screen. They might have then described CSS as a supplementary file that the HTML file calls so that stylistic definitions apply consistently across tags defined with certain named classes. Finally, JavaScript might have similarly been described as the exclusive source of any interactive or animated element that the HTML hosts.

While these three basic scripts can still be used this way, recent years' advances in the power and broadness of each script's functionality has essentially allowed HTML and CSS files to host their respective portions of interlocking syntax that provides self-animating effects. CSS is now capable of initiating animation as soon as the effect is loaded, and the effects can also be made to animate themselves when elements are rolled over or clicked. These effects exist in what is called the SVG format; because lines of web syntax are all that contemporary browsers need to render them, impressive self-animating effects can be expressed without much processing power or need to download large media files.

An exhibition on codepen.io showcases how a CSS-based animation can produce an effect that would appear to be dynamically generated and give the illusion of transpiring in a three-dimensional space. Despite the striking movement of the ball-shaped image that is made to bounce off floating walls interminably, however, there is no usage of JavaScript syntax whatsoever. The effect is technically proceeding linearly and reliably without any true dynamic generation allowing for incidental occurrences. Since the potential for outcomes beyond the author's control is what JavaScript is often used for, a hypothetical version of this same project in which a wall can be adjusted so that the ball would bounce in a different direction upon contact would have to use JavaScript.
