![]() ![]() We're using an article tag here, but any HTML element can be substituted. Let's begin by establishing the first fundamental HTML element: the stage. Note that the second and third aspects at the beginning of the animation appear identical to the first and second aspects at the end of the animation. Here's what that same setup looks like with three aspects:Īfter the overflow: hidden is applied, two of the three aspects are fully visible at any given time. Then, just apply an overflow: hidden to the stage and its sides begin to behave correctly as theatre curtains to complete the illusion of perpetual motion within the visible area:Īs you can see, one of two aspects is fully visible at any given time. When the belt completes a single iteration of its animation, it instantly teleports back to its original location, where the last aspect of the sequence (Aspect #2) visually replaces the first aspect of the sequence (Aspect #1) and continues its journey on the next iteration of the animation. Animate the belt until its left side reaches the left-most edge of the stage. Start with the right side of the belt at the right-most edge of the stage. That means the last aspect of the sequence (Aspect #2) must visually appear in the exact same position on the screen in which the first aspect of the sequence (Aspect #1) will appear at the end of a single iteration of the animation. This animation has two aspects where one aspect will be visible at any given time. They determine how many aspects will appear within the visible area at any given moment of the animation. The width and the offset distance of the belt are significant. ![]() In this example, the intention is to animate the aspects from the left to the right of the stage, so we start with the position of the belt offset to the left of the stage. Note: even spacing is achieved here with Flexbox's justify-content: space-around.All aspects must be evenly spaced along the belt.The first and last aspect(s) must be identical.There must be at least two aspects in the sequence.Whatever elements you choose, there are several rules: generator produce linear, radial, elliptical and conial gradients that can be used in your web page design or android apps. Aspects - A sequence of visually-distinguishable elements within the belt. Angrytools - Online Gradient Generater interface to generate cross browser CSS gradient code as well as Android gradient code.This is what actually performs the animation. Items on top of it are stationary but the belt moves items through space. Think of this like a portion of a conveyor belt at the grocery store. Belt - A child container nested within the stage to house visually-distinguishable elements.For now, everything is visible for demonstration purposes. Anything that goes from the visible area of the stage to behind the curtains will be invisible to the audience. Think of this like a theatre stage, where the left and right sides are blocked by curtains. Of course, other tools are available, but they didn’t allow for defining multi-layered and more complex gradients. It started from the frustration of having to specify the CSS gradient syntax by hand without having immediate feedback. Stage - A parent container that designates where the visible area of the animation begins and ends. Gradient Generator, ColorGradient is a simple tool for you to build simple and complex gradients.This animation technique uses several elements to achieve this effect.įirst, let's establish those elements and their vocabulary in a scene: This is not the only animation technique for gradients, but I've found it's one of the more elegant and versatile. You can find the full code for this demo here.In this article, I will demonstrate how to animate gradients in an infinite, linear fashion using nothing but HTML and CSS. Now it's up to you what gradient you want! Just adjust the background-image colors to show the gradient style you desire. filter - since we're using background clips and text, we can use a filter for the drop shadow rather than a normal box shadow. ![]()
