radial-gradients

问题 I have a radial gradient that used as a mask-image "fades" an image in to the background-color behind the image. mask-image: radial-gradient(ellipse at center, rgba(255,255,255,1) 1%,rgba(255,255,255,1) 50%,rgba(255,255,255,0) 70%,rgba(255,255,255,0) 100%); How do I get the same effect with an evenly rectangular gradient on all four sides? I know you can combine gradients and my most current attempt does not seem to have any effect: img { mask-image: linear-gradient(to top, rgba(255,255,255,1

问题 I have this radial gradient expressed in objectBoundingBox coordinates. <svg width="300" height="300"> <defs> <radialGradient id="MyGradient" gradientUnits="objectBoundingBox" cx="0.3" cy="0.4" r="0.3" fx="0.1" fy="0.2"> <stop offset="0%" stop-color="red" /> <stop offset="50%" stop-color="blue" /> <stop offset="100%" stop-color="black" /> </radialGradient> </defs> <rect fill="url(#MyGradient)" stroke="black" stroke-width="5" x="50" y="100" width="200" height="100"/> </svg> Is it possible to

问题 I tried to add a (radial) gradient as background (in Android 4.0), either as background image or programmatically but none of them never works. I can only test it in emulator, but I guess it's the same on a 4.0 device. These solutions don't work: Placing in raw folder. (Disable Android resource / image / png optimization) Making a proxy xml with dithering and anti aliasing true, as well as saving opacy of png to 99%. (android:dither="true" does not dither, what's wrong?) Overriding

问题 I have the following arc diagram: I would like to add a gradient to each of the individual arcs, that flows from the outer radius to the inner radius of each individual arc. I am guessing that I will need to create an individual gradient for each arc? let radius = 100; for(let i = 0; i < 5; i ++) { let grad = defs.append('radialGradient') .attr('id', 'mygrad' + i) .attr('gradientUnits', 'userSpaceOnUse') .attr('cx', '0') .attr('cy', '0') .attr('r', radius) grad.append('stop') .attr('offset',

问题 I am trying to use radial gradient for my background and below is the code. div { width: 778px; height: 100px; background: radial-gradient(ellipse at top center, green, yellow 229px); background-size: 100% 100%; background-position: 0% 0%; } <div></div> When I increase the height of the div it is appearing as But we want to have fixed vertical radius for ellipse in radiant like below one I tried to play around the background-size but the height of the div is not fixed. so I really cant set

问题 I found this nice button on CodePen that inverts the button color with a ripple effect, using a radial-gradient animation. I need it to have a 28px border radius , but then a jagged border appears as shown here. html { box-sizing: border-box; height: 100%; font-size: 10px; } *, *::before, *::after { box-sizing: inherit; } body { display: flex; align-items: center; justify-content: center; min-height: 100vh; background: #57bd84; } input[type=checkbox] { height: 0; width: 0; visibility: hidden;

问题 Is there an package, or another way to have a simple, let's say blue to blueish, radial gradient background, for one of the views? I've tried react-native-radial-gradient, but it seems like it's outdated. 回答1: Probably you can use RadialGradient from my react-native-image-filter-kit package. Note that gradients from react-native-image-filter-kit are initially designed as primitives for blending with other images and your case is not something that was taken into account in the first place.
