实用 CSS 特效
一、svg 实现跳转 github 图标
在查阅文档时, 经常看到这个分享图标, 鼠标移上去还会动, 以为很是麻烦, 就是一个 svg 图标
搭建个人博客等网站时,也可以把这个按钮添加进来, 有点技术元素了没! 先上效果:
超简单使用: 代码
<!-- 右上角 github corner -->
<div class="svg-wrap">
<a href="https://your-url/" target="_blank" class="github-corner">
<svg width="80" height="80" viewBox="0 0 250 250" style="fill:#b45dea; color:#fff; position: absolute; top: 0; border: 0; right: 0;" aria-hidden="true">
<path d="M0,0 L115,115 L130,115 L142,142 L250,250 L250,0 Z"></path>
<path d="M128.3,109.0 C113.8,99.7 119.0,89.6 119.0,89.6 C122.0,82.7 120.5,78.6 120.5,78.6 C119.2,72.0 123.4,76.3 123.4,76.3 C127.3,80.9 125.5,87.3 125.5,87.3 C122.9,97.6 130.6,101.9 134.4,103.2" fill="currentColor" style="transform-origin: 130px 106px;" class="octo-arm"></path>
<path d="M115.0,115.0 C114.9,115.1 118.7,116.5 119.8,115.4 L133.7,101.6 C136.9,99.2 139.9,98.4 142.2,98.6 C133.8,88.0 127.5,74.4 143.8,58.0 C148.5,53.4 154.0,51.2 159.7,51.0 C160.3,49.4 163.2,43.6 171.4,40.1 C171.4,40.1 176.1,42.5 178.8,56.2 C183.1,58.6 187.2,61.8 190.9,65.4 C194.5,69.0 197.7,73.2 200.1,77.6 C213.8,80.2 216.3,84.9 216.3,84.9 C212.7,93.1 206.9,96.0 205.4,96.6 C205.1,102.4 203.0,107.8 198.3,112.5 C181.9,128.9 168.3,122.5 157.7,114.1 C157.9,116.9 156.7,120.9 152.7,124.9 L141.0,136.5 C139.8,137.7 141.6,141.9 141.8,141.8 Z" fill="currentColor" class="octo-body" ></path>
</svg>
</a>
</div>
二、四角边框
需求: 是不是似曾相识..
实现效果如下:
Talk is cheap, show the codes
<div class="card-wrapper">
<div class="content-box"></div>
</div>
.card-wrapper {
display: inline-block;
padding: 13px;
background: linear-gradient(#00ffd4, #00ffd4) left top, linear-gradient(#00ffd4, #00ffd4) left top,
linear-gradient(#00ffd4, #00ffd4) right top, linear-gradient(#00ffd4, #00ffd4) right top,
linear-gradient(#00ffd4, #00ffd4) left bottom, linear-gradient(#00ffd4, #00ffd4) left bottom,
linear-gradient(#00ffd4, #00ffd4) right bottom, linear-gradient(#00ffd4, #00ffd4) right bottom;
background-repeat: no-repeat;
background-size: 2px 20px, 20px 2px;
}
.content-box {
width: 213px;
height: 132px;
border: #b45dea 1px solid;
background: rgba(213, 213, 213, 0.3);
}
三、渐变边框的探索
1. 最原始方案: 背景组合 叠加产生渐变边框
父元素使用背景渐变 linear-gradient, 再通过叠加一个其他颜色的背景盖在上面, 即子(伪)元素使用背景 background 盖住, 从而达到渐变边框的需求. 效果如下:
非常简单,简单的示意图如下:
实现代码如下:
<div class="box bd-6">
<div class="content bd-6">1. 背景组合产生渐变边框</div>
</div>
<div class="box">
<div class="content">1. 背景组合产生渐变边框</div>
</div>
.bd-6 {
border-radius: 6px;
}
.box {
width: 270px;
height: 66px;
background: linear-gradient(145deg, #0061fe, #ff00f0);
}
.content {
width: 265px;
height: 60px;
font-size: 18px;
color: #fff;
text-align: center;
margin: 3px;
background-color: rgb(24, 24, 24);
}
同理也可以使用 伪元素 ::before 和 ::after, 这样一个标签就可实现了,
但是如果需求背景是透明的就不行了
2. CSS3 border 属性 border-image
前面的实现方法都是使用了多个标签, 不雅也不推荐,
根据 CSS3 找到最新实现方案: border-image 我们可以给 border 元素添加 image, 类似于 background-image,可以是渐变也可以是图片, 也可背景透明, 但设置圆角会失效。
具体语法可以参考: border-image
<div class="border-image">border-image</div>
.border-image {
width: 200px;
height: 100px;
/* 这里边框类型没有效果 但仍需设置 */
border: 10px solid;
/* 圆角失效 */
border-radius: 10px;
border-image-source: linear-gradient(145deg, #0061fe, #ff00f0);
border-image-slice: 1;
border-image-repeat: stretch;
}
border-radius 失效
3. 使用 background-clip
只需一个单独的标签即可,
同样: 如果需求背景是透明的就不行了
.bg-clip {
width: 200px;
height: 100px;
border: solid 10px transparent;
border-radius: 10px;
background-image: linear-gradient(#fee, #fee), linear-gradient(to right, green, gold);
background-origin: border-box;
background-clip: content-box, border-box;
}
4. clip-path
<div class="border-image-clip-path"></div>
.border-image-clip-path {
position: relative;
width: 200px;
height: 80px;
border: 10px solid;
border-image: linear-gradient(45deg, #0061fe, #ff00f0) 1;
clip-path: inset(0 round 10px);
}
另外,还可以用 filter: hue-rotate() 再加个渐变动画:
.border-image-clip-path {
filter: hue-rotate(360deg);
}
@keyframes huerotate {
0% {
filter: hue-rotate(0deg);
}
100% {
filter: hue-rorate(360deg);
}
}
边框背景渐变动画:
四、渐变字体
<h2 class="gradient-text">
gradient Text gradient Text gradient Text gradient Text gradient Text gradient Text
</h2>
.gradient-text {
background-image: linear-gradient(to right, #0061fe, #ff00f0);
-webkit-background-clip: text;
background-clip: text;
color: transparent;
text-transform: uppercase;
}
五、在售状态标志
比较原始的方案: 采用定位方法...后续更新...
<div class="box">
<div class="badge">ON SALE</div>
<img
src="https://cdn.jsdelivr.net/gh/xn213/img-hosting@master/juejin-posts-imgs/compare_mbp16__fykfvftfaeuu_large.6fi0c3rwsq00.png"
alt=""
/>
</div>
.box {
width: 200px;
height: 200px;
position: relative;
overflow: hidden;
}
.badge {
position: absolute;
top: 20px;
left: -30px;
background: red;
color: #fff;
width: 120px;
text-align: center;
transform: rotate(-45deg);
}
