🎨 Vue 2 背景颜色渐变实现方式汇总

1️⃣ 线性渐变（Linear Gradient）

<template><div class="linear-bg"><h1>线性渐变背景</h1></div>
</template><style scoped>
.linear-bg {height: 100vh;background: linear-gradient(to right, #ff7e5f, #feb47b);
}
</style>

📌 可选方向：

to bottom
to top right
45deg（角度）

2️⃣ 径向渐变（Radial Gradient）

<template><div class="radial-bg"><h1>径向渐变背景</h1></div>
</template><style scoped>
.radial-bg {height: 100vh;background: radial-gradient(circle, #ffefba, #ffffff);
}
</style>

📌 可选形状：

circle
ellipse

3️⃣ 多色渐变（Multi-color Gradient）

<template><div class="multi-bg"><h1>多色渐变背景</h1></div>
</template><style scoped>
.multi-bg {height: 100vh;background: linear-gradient(to right, red, orange, yellow, green, blue, indigo, violet);
}
</style>

📌 用于炫彩背景、节日氛围等场景。

4️⃣ 动态渐变（通过 `data` 或 `computed` 控制）

<template><div :style="gradientStyle"><input type="color" v-model="colorStart" /><input type="color" v-model="colorEnd" /></div>
</template><script>
export default {data() {return {colorStart: '#ff7e5f',colorEnd: '#feb47b'};},computed: {gradientStyle() {return {height: '100vh',background: `linear-gradient(to right, ${this.colorStart}, ${this.colorEnd})`};}}
};
</script>

📌 用户可实时调整颜色，适合主题切换或个性化设置。

5️⃣ 渐变按钮或导航栏

<template><button class="gradient-btn">点击我</button>
</template><style scoped>
.gradient-btn {padding: 10px 20px;border: none;border-radius: 5px;background: linear-gradient(to right, #6a11cb, #2575fc);color: white;font-size: 16px;cursor: pointer;
}
</style>

📌 渐变可用于按钮、卡片、导航栏等局部组件。

6️⃣ 多层渐变叠加（高级效果）

<template><div class="layered-bg"><h1>多层渐变背景</h1></div>
</template><style scoped>
.layered-bg {height: 100vh;background: linear-gradient(to bottom, rgba(255,0,0,0.5), rgba(255,0,0,0)),radial-gradient(circle, rgba(0,255,0,0.5), rgba(0,255,0,0));
}
</style>

📌 可用于玻璃拟态、模糊背景等视觉增强。

7️⃣ 渐变动画（背景颜色动态变化）

<template><div class="animated-bg"><h1>渐变动画背景</h1></div>
</template><style scoped>
.animated-bg {height: 100vh;animation: gradientShift 5s infinite alternate;background: linear-gradient(270deg, #ff6ec4, #7873f5);background-size: 400% 400%;
}@keyframes gradientShift {0% {background-position: 0% 50%;}100% {background-position: 100% 50%;}
}
</style>

📌 适合炫酷首页或加载页。

8️⃣ 响应式渐变（根据窗口大小或状态变化）

<template><div :style="responsiveGradient"><h1>响应式渐变背景</h1></div>
</template><script>
export default {data() {return {width: window.innerWidth};},computed: {responsiveGradient() {const color = this.width > 768 ? '#00c6ff' : '#f77062';return {height: '100vh',background: `linear-gradient(to right, ${color}, #ffffff)`};}},mounted() {window.addEventListener('resize', () => {this.width = window.innerWidth;});}
};
</script>

📌 可用于移动端适配或暗/亮模式切换。

9️⃣ SVG 渐变背景（更复杂的图形渐变）

<template><div class="svg-bg"><svg width="100%" height="100%"><defs><linearGradient id="grad1" x1="0%" y1="0%" x2="100%" y2="0%"><stop offset="0%" style="stop-color:#ff7e5f;stop-opacity:1" /><stop offset="100%" style="stop-color:#feb47b;stop-opacity:1" /></linearGradient></defs><rect width="100%" height="100%" fill="url(#grad1)" /></svg></div>
</template><style scoped>
.svg-bg {height: 100vh;overflow: hidden;
}
</style>

📌 适合需要精细控制渐变路径的场景。
