# 怎么使用CSS画一个棒棒糖
## 引言
在网页设计中,CSS不仅能控制布局和样式,还能通过纯代码创建有趣的图形效果。本文将手把手教你用CSS绘制一个可爱的棒棒糖,涵盖圆形绘制、条纹效果、阴影处理以及棒棒糖棍的制作技巧。通过这个案例,你将掌握CSS的`border-radius`、`linear-gradient`、`box-shadow`等核心属性的创意用法。

## 一、基础HTML结构
首先创建最简单的HTML骨架,只需要一个`div`元素作为容器:
```html
<!DOCTYPE html>
<html lang="zh-CN">
<head>
<meta charset="UTF-8">
<title>CSS棒棒糖</title>
<link rel="stylesheet" href="styles.css">
</head>
<body>
<div class="lollipop">
<div class="candy"></div>
<div class="stick"></div>
</div>
</body>
</html>
在CSS文件中初始化基本样式:
body {
display: flex;
justify-content: center;
align-items: center;
min-height: 100vh;
background-color: #f0f8ff;
margin: 0;
}
.lollipop {
position: relative;
width: 200px;
height: 300px;
}
.candy {
width: 150px;
height: 150px;
border-radius: 50%;
position: absolute;
top: 0;
left: 25px;
}
使用conic-gradient
创建彩虹色条纹:
.candy {
background: conic-gradient(
#ff0000 0deg 45deg,
#ff9900 45deg 90deg,
#ffff00 90deg 135deg,
#33cc33 135deg 180deg,
#0099ff 180deg 225deg,
#6633cc 225deg 270deg,
#cc3399 270deg 315deg,
#ff0000 315deg 360deg
);
box-shadow: 0 5px 15px rgba(0,0,0,0.2);
}
用伪元素创建反光点增强立体感:
.candy::after {
content: "";
position: absolute;
width: 40px;
height: 40px;
background: rgba(255,255,255,0.7);
border-radius: 50%;
top: 20px;
right: 20px;
filter: blur(2px);
}
.stick {
position: absolute;
width: 20px;
height: 150px;
background: linear-gradient(to bottom, #f5deb3, #d2b48c);
bottom: 0;
left: 90px;
border-radius: 0 0 10px 10px;
}
使用伪元素创建条纹细节:
.stick::before {
content: "";
position: absolute;
width: 100%;
height: 100%;
background: linear-gradient(
90deg,
transparent 40%,
rgba(0,0,0,0.1) 40%,
rgba(0,0,0,0.1) 60%,
transparent 60%
);
}
用border
模拟塑料薄膜效果:
.candy {
border: 3px solid rgba(255,255,255,0.3);
}
添加无限旋转动画:
@keyframes spin {
from { transform: rotate(0deg); }
to { transform: rotate(360deg); }
}
.lollipop:hover .candy {
animation: spin 3s linear infinite;
}
根据光源位置调整阴影:
.lollipop {
filter: drop-shadow(5px 10px 5px rgba(0,0,0,0.3));
}
/* 完整样式汇总 */
body {
display: flex;
justify-content: center;
align-items: center;
min-height: 100vh;
background-color: #f0f8ff;
margin: 0;
}
.lollipop {
position: relative;
width: 200px;
height: 300px;
filter: drop-shadow(5px 10px 5px rgba(0,0,0,0.3));
}
.candy {
width: 150px;
height: 150px;
border-radius: 50%;
position: absolute;
top: 0;
left: 25px;
background: conic-gradient(
#ff0000 0deg 45deg,
#ff9900 45deg 90deg,
#ffff00 90deg 135deg,
#33cc33 135deg 180deg,
#0099ff 180deg 225deg,
#6633cc 225deg 270deg,
#cc3399 270deg 315deg,
#ff0000 315deg 360deg
);
box-shadow: 0 5px 15px rgba(0,0,0,0.2);
border: 3px solid rgba(255,255,255,0.3);
}
.candy::after {
content: "";
position: absolute;
width: 40px;
height: 40px;
background: rgba(255,255,255,0.7);
border-radius: 50%;
top: 20px;
right: 20px;
filter: blur(2px);
}
.stick {
position: absolute;
width: 20px;
height: 150px;
background: linear-gradient(to bottom, #f5deb3, #d2b48c);
bottom: 0;
left: 90px;
border-radius: 0 0 10px 10px;
}
.stick::before {
content: "";
position: absolute;
width: 100%;
height: 100%;
background: linear-gradient(
90deg,
transparent 40%,
rgba(0,0,0,0.1) 40%,
rgba(0,0,0,0.1) 60%,
transparent 60%
);
}
@keyframes spin {
from { transform: rotate(0deg); }
to { transform: rotate(360deg); }
}
.lollipop:hover .candy {
animation: spin 3s linear infinite;
}
radial-gradient
制作糖晶体质感transform-style: preserve-3d
和透视变换clamp()
函数实现尺寸自适应通过这个案例,我们实践了: - 圆形绘制与渐变色的结合 - 伪元素的创意使用 - CSS动画的简单应用 - 细节质感的营造技巧
CSS图形绘制既能锻炼编码能力,又能培养设计思维。试着用这些技术创造更多有趣的图形吧! “`
