Timing functions are responsible for controlling the speed of a CSS animation or transition. They allow you to change the speed throughout the animation, making it speed up or slow down at different points. In this article, we’ll cover everything you need to know about CSS timing functions.
We'll dive into the world of timing functions, unraveling their role in shaping the rhythm and tempo of CSS animations. Whether you're a seasoned developer or just starting out in the realm of web design, join me as we navigate through the basics of timing functions. Together, we'll make these concepts less puzzling and more like valuable tools in your web development toolkit. Get ready to enhance your mastery of CSS animations!
The options available for timing functions provide developers with a range of choices to tailor the visual experience of their websites or applications. For instance, the 'linear' option ensures a consistent animation speed throughout, creating a straightforward and predictable effect. On the other hand, the 'ease' option delivers a smooth start and gradual deceleration, often serving as the default choice for animations due to its natural and visually pleasing transition. Developers can further customize animations by exploring options like 'ease-in,' 'ease-out,' 'ease-in-out,' or even crafting intricate curves with the 'cubic-bezier' option. This flexibility empowers developers to fine-tune animations, enhancing user engagement and visual appeal.
Experimenting with these CSS timing function options is not only an essential part of the creative process but also a practical approach to achieving the desired look and feel for a website or application. By selecting and combining different timing functions, developers can create animations that align seamlessly with their design goals. Whether aiming for a constant pace, a gentle ease-in effect, or a more complex and unique animation curve, understanding and utilizing these timing function options allows developers to infuse life into their web projects. As developers explore the diverse possibilities, they gain a deeper appreciation for the artistry behind CSS animations, enabling them to deliver a more engaging and visually compelling user experience.

As you can see, the transition property is useless without the width property. You need to define the initial state of the element, and then the final state. The transition property will take care of the rest. In the example above we set the regular width like any other property and we also set the final state with ":hover" pseudo-class.
transition: things-to-be-animated duration timing-function delay;
The things-to-be-animated are the properties you want to animate; in our case, it's the width. However, I usually put the value 'all' in this spot just because it makes things easier. Essentially, I am telling CSS that everything can be animated. The duration is the time it takes for the animation to complete, and it can be in seconds or milliseconds. The timing function determines the speed of the animation, which can be linear, ease, ease-in, ease-out, ease-in-out, or cubic-bezier, if you have no idea what this is I recommend you check this out (What the hell are timing functions ?). The delay is the time it takes for the animation to start and can be in seconds or milliseconds.
I highly recommend you check out some of my animations, most of them make use of CSS transitions.
