To do that, skip the text shadow on the emojis. Instead of using plain emoji icons, we can use gradient emoji icons. Other than emojis, it’s also possible to draw CSS shapes and use them as patterns. Like linear and radial gradients, conic gradients can be used to create geometric patterns. ![]() Conic gradient patternsĬonic gradients create ray-like shapes. That’s followed by the gradient color values along with the start and ending positions within the gradient. The first two parameters for a radial gradient function determine whether the gradient shape is a circle or an ellipse and the starting position of the gradient. Black circles are scattered across to represent the watermelon seeds. An ellipse forms the green and red parts. We start by providing a background size on the element then stack up the gradients inside it. Radial-gradient(ellipse at 50px 0, red 33px, lime 33px, lime 38px, transparent 38px) Radial-gradient(circle at 70px 16px, black 2px, transparent 2px), Radial-gradient(circle at 60px 16px, black 2px, transparent 2px), ![]() Radial-gradient(circle at 50px 10px, black 2px, transparent 2px), Radial-gradient(circle at 80px 4px, black 2px, transparent 2px), Radial-gradient(circle at 20px 4px, black 2px, transparent 2px), Radial-gradient(circle at 38px 1px, black 2px, transparent 2px), Radial-gradient(circle at 49px 28px, black 2px, transparent 2px), Radial-gradient(circle at 25px 9px, black 2px, transparent 2px), Here’s a pattern of repeating watermelons using this technique: Both can be used for patterns that are very interesting and might unlock some ideas for you! background: radial-gradient() Let’s look at radial gradients first because they give us very useful things: circles and ellipses. I recommend checking out the syntax for all the gradients to thoroughly understand how to start and end a color in a gradient. conic-gradient(): Similar in concept to radial gradients, but the color stops are placed around the circle rather than emanating from the center point.radial-gradient(): Colors start at a single point and emanate outward.linear-gradient(): Colors flow from left-to-right, top-to-bottom, or at any angle you choose in a single direction.Linear (left), radial (center) and conic (right) gradients But there are other ways to create cool background patterns. Let’s see how we can use gradients in other ways and toss in other things, like CSS shapes and emoji, to spice things up. Linear gradients (and repeating linear gradients) for instance, are typically used for stripes. They can be done by referencing an external image, like a PNG file, or can be drawn with CSS, which is traditionally done using CSS gradients. Thankfully, we can conjure up far more background patterns than you can even imagine with CSS, with code that is similar in spirit to stripes.īackground patterns are images repeated across a background. Too conventional, out of fashion, and sometimes even unpleasant. They can be customized into wide and narrow bands, criss-crossed into a checked pattern, and played with in other ways using the idea of hard stops. There’s nothing wrong with stripes stripes are cool. That’s all I thought about in terms of CSS background patterns for a long time. Survival analysis supported the predictions, indicating that disruptive coloration is an effective means of camouflage, above and beyond background pattern matching.You can create stripes in CSS. Artificial moth-like targets were exposed to bird predation in the field, with the experimental colour patterns on the 'wings' and a dead mealworm as the edible 'body'. Here we test two key predictions: that patterns on the body's outline should be particularly effective in promoting concealment and that highly contrasting colours should enhance this disruptive effect. Surprisingly, only one quantitative test of the theory exists, and one experimental test of its effectiveness against non-human predators. The latter has long been proposed as an explanation for some apparently conspicuous coloration in animals, and is standard textbook material. ![]() Two interrelated but logically distinct mechanisms for this are background pattern matching (crypsis) and disruptive coloration: in the former, the animal's colours are a random sample of the background in the latter, bold contrasting colours on the animal's periphery break up its outline. Effective camouflage renders a target indistinguishable from irrelevant background objects.
