1 基础实现
templateBox 测试 /Box
/template
script setup langts
import Box from ./Box.vue;
/script
style scoped/styletemplatediv classboxdiv classcontentslot/slot/div/div
/template
script setup langts/script
style scoped langscss
.box {display: flex;justify-content: center;align-items: center;text-align: center;position: relative;width: 100%;height: 100%;padding: 5px;border-radius: 10px;overflow: hidden;:before {content: ;background-image: linear-gradient(120deg, #5ddcff, #3c67e3 40%, #4e00c2);position: absolute;z-index: 0;padding-left: 130%;padding-bottom: 130%;animation: rotate 8s linear infinite;}.content {height: 100%;width: 100%;display: flex;align-items: center;padding: 24px 20px;background: #f1d674;z-index: 2;border-radius: 6px;}
}
keyframes rotate {0% {transform: rotate(0deg);}100% {transform: rotate(360deg);}
}
/style 动图略 2 封装组件
2.1 圆形边框
使用mask属性使得中间部分背景不被遮挡
templatediv classbox :style{ width: width px, height: height px }slot/slot/div
/template
script setup langts
const props defineProps({width: {type: Number, //容器宽default: 100,},height: {type: Number, //容器高default: 100,},colors: {//颜色数组type: Array,default: () [{color: #64dcfd,width: 0,},{color: #406cf1,width: 100,},{color: #4501ac,width: 101,},],},angle: {//渐变角度type: Number,default: 120,},borderWidth: {//流光边框宽度type: Number,default: 10,},gradient: {//是否渐变type: Boolean,default: true,},duration: {//动画时间type: String,default: 5s,},
});const background computed(() {const positions [];const colorsCopy JSON.parse(JSON.stringify(props.colors));colorsCopy.forEach((s, index) {const sum colorsCopy.slice(0, index).reduce((a, b) a b.width, 0);if (!props.gradient) {positions.push(sum);}positions.push(sum s.width);});return linear-gradient(${props.angle}deg, ${colorsCopy.map((s, index) {if (!props.gradient) {return ${s.color} ${positions[index]}px, ${s.color} ${positions[2 * index 1]}px;}return ${s.color} ${positions[index]}px;}).join(,)});

});
/script
style scoped langscss
.box {display: flex;justify-content: center;align-items: center;position: relative;width: 100%;height: 100%;border-radius: 50%;overflow: hidden;:before {content: ;background-image: v-bind(background);position: absolute;width: 100%;height: 100%;border-radius: 50%;animation: rotate v-bind(duration) linear infinite;mask: radial-gradient(transparent,transparent v-bind(borderLRShink),#000 v-bind(borderLR));-webkit-mask: radial-gradient(transparent,transparent v-bind(borderLRShink),#000 v-bind(borderLR));}
}
keyframes rotate {0% {transform: rotate(0deg);}100% {transform: rotate(360deg);}
}

2.2 矩形边框
使用伪元素自定义中间部分背景
templatediv classbox :style{ width: width px, height: height px }slot/slot/div
/template
script setup langts

});const background computed(() {const positions [];const colorsCopy JSON.parse(JSON.stringify(props.colors));colorsCopy.forEach((s, index) {const sum colorsCopy.slice(0, index).reduce((a, b) a b.width, 0);if (!props.gradient) {positions.push(sum);}positions.push(sum s.width);});return linear-gradient(${props.angle}deg, ${colorsCopy.map((s, index) {if (!props.gradient) {return ${s.color} ${positions[index]}px, ${s.color} ${positions[2 * index 1]}px;}return ${s.color} ${positions[index]}px;}).join(,)});
});const innerWidth computed(() {let doubleBorderWidth 0;if (Array.isArray(props.borderWidth)) {if (props.borderWidth.length 2) {doubleBorderWidth props.borderWidth[1] * 2;} else if (props.borderWidth.length 1) {doubleBorderWidth props.borderWidth[0] * 2;}} else {doubleBorderWidth props.borderWidth * 2;}return props.width - doubleBorderWidth px;
});
const innerheight computed(() {let doubleBorderWidth 0;if (Array.isArray(props.borderWidth)) {if (props.borderWidth.length 2) {doubleBorderWidth props.borderWidth[0] * 2;} else if (props.borderWidth.length 1) {doubleBorderWidth props.borderWidth[0] * 2;}} else {doubleBorderWidth props.borderWidth * 2;}return props.height - doubleBorderWidth px;
});
const colorSize computed(() {return (Math.ceil(Math.sqrt(props.width * props.width props.height * props.height)) px);
});
/script
style scoped langscss
.box {display: flex;justify-content: center;align-items: center;position: relative;width: 100%;height: 100%;overflow: hidden;:before {content: ;background-image: v-bind(background);position: absolute;width: v-bind(colorSize);height: v-bind(colorSize);animation: rotate v-bind(duration) linear infinite;}:after {content: ;background: v-bind(innerBackground);position: absolute;z-index: 1;width: v-bind(innerWidth);height: v-bind(innerheight);}
