🎨 Vue 2 背景颜色渐变实现方式汇总

1 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）

2 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

3 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。

4 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。

5 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。

6 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。

7 渐变动画（背景颜色动态变化）

}@keyframes gradientShift {0% {background-position: 0% 50%;}100% {background-position: 100% 50%;}
}
</style>

📌 适合炫酷首页或加载页。

8 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。

9 SVG 渐变背景（更复杂的图形渐变）

</template><style scoped>
.center-horizontal {height: 100vh;background: linear-gradient(to left, white, #3498db 50%, white);
}
</style>

📌 说明：

渐变从中间颜色（蓝色）向左右两边变白
to left 表示从右向左绘制，但颜色顺序是从左到右定义的

19 从中间向上下渐变为白（垂直展开）

<template><div class="center-vertical"><h1>从中间向上下渐变为白</h1></div>
</template><style scoped>
.center-vertical {height: 100vh;background: linear-gradient(to top, white, #3498db 50%, white);

20 从中间斜向左上和右下渐变（对角线展开）

<style scoped>
.center-diagonal {height: 100vh;background: linear-gradient(135deg, white, #3498db 50%, white);
}
</style>

📌 135deg 表示从左上到右下方向绘制，颜色在中间最深，两端变浅。

21 使用径向渐变模拟中心向四周扩散

<template><div class="radial-center"><h1>使用径向渐变模拟中心向四周扩散</h1></div>
</template><style scoped>
.radial-center {height: 100vh;background: radial-gradient(circle at center, #3498db 0%, white 100%);
}
</style>

}
</style>

📌 颜色从白 → 浅蓝 → 深蓝 → 浅蓝 → 白，形成更柔和的过渡。
