Revolutionizing UI Motion Design: Unpacking the Power of Linear() in CSS

As Seen On

In the brave new world of digital interfaces, the sophistication of a product’s motion design can be the determining factor between its success or failure. Aiming to create animations that are not just aesthetically pleasing but also natural in their look and feel – complimenting, rather than interrupting, a user’s interaction – is a significant goal of modern-day UI designers.

One of the key ways to achieve this is through the use of Cascading Style Sheets (CSS). Recent advancements in CSS like the powerful new easing function, linear(), are providing developers with advanced easing capabilities required to craft incredibly natural UI movements.

The Ascent of Motion Design

The evolution of UI design has seen a macro-shift from static, unresponsive interfaces to dynamic, user-focused experiences. Integral to this shift is motion design. When incorporated effectively, it breathes life into interfaces, guiding users seamlessly through their digital journey.

Motion design endows web pages and apps with a fluidity that mimics the natural world. Subtle animations and transitions fade in and out, slide, bounce, and spring, creating a sense of depth and realism that traditional design methods simply can’t emulate.

Exploring the Linear() Function

In CSS Easing Level 2, a cutting-edge easing function, linear(), is ripe for exploration. Whilst still in its Editor’s Draft stage, implying there could be modifications in the future, the introduction of linear() marks a significant step forward in UI motion design.

Although limited support is currently available for linear(), budding CSS developers are closely monitoring its progress since this function may well revolutionize the way we craft UI animations and transitions.
A Wealth of Resources

This exciting journey into the world of UI motion design wouldn’t be comprehensive without acknowledging the pioneering work of industry experts such as Pablo Stanley and Ruthiran Babu. Their insights and thought-leading articles provide a rich and valuable resource to both new and seasoned designers wanting to immerse themselves in state-of-the-art UI motion design.

Unpacking Easing in CSS

Creating animations and transitions in CSS classically has meant utilizing the animation-timing-function or transition-timing-function properties. These properties, paired with easing functions, have historically controlled the interaction speed and flow of user interfaces.

Classic ease effects derived from CSS include linear, steps, ease, ease-in, ease-out, ease-in-out, and cubic-bezier(). However, these functions were not without their limitations, especially when it came to the degree of naturalism in animations and transitions achievable.

Harnessing the Power of Linear()

The value of linear() becomes apparent when compared with the more traditional CSS easing function, cubic-bezier(). Cubic-bezier(), whilst extremely powerful, falls short when trying to achieve more complex easing effects such as bounce or spring.

This is where linear() turns it up a notch. Offering an advanced easing solution for these effects, it makes the impossible possible, allowing a developer to harness the physics of the natural world within their designs.

Creating intuitive and natural-feeling animations that enhance a user’s interaction is the beating heart of progressive UI motion design. The advent and evolution of CSS’s linear() function holds the promise for even more lifelike digital experiences, pushing the boundaries of what’s possible in the realm of UI motion design.

Up until working with Casey, we had only had poor to mediocre experiences outsourcing work to agencies. Casey & the team at CJ&CO are the exception to the rule.

Communication was beyond great, his understanding of our vision was phenomenal, and instead of needing babysitting like the other agencies we worked with, he was not only completely dependable but also gave us sound suggestions on how to get better results, at the risk of us not needing him for the initial job we requested (absolute gem).

This has truly been the first time we worked with someone outside of our business that quickly grasped our vision, and that I could completely forget about and would still deliver above expectations.

I honestly can't wait to work in many more projects together!
