CSS奇思妙想图形(心形、气泡三角形、切角、梯形、饼图等)

 今天看到一篇不错文章,在原来CSS3图形创建基础上扩展了很多。

这里记录总结下

心形

CSS奇思妙想图形(心形、气泡三角形、切角、梯形、饼图等)_第1张图片

原理:利用 圆形 和 正方形实现

HTML:

<div class="heartShaped">
    <h1>heartShapedh1>
div>

CSS:

.heartShaped {
    position: absolute;
    top: 50%;
    left: 50%;
    transform: translate(-50%, -50%) rotate(45deg);
    background: rgba(255, 20, 147, .85);
    width: 140px;
    line-height: 140px;
    text-align: center;
    color: white;
    font-size: 12px;
}

.heartShaped:before, .heartShaped:after {
    content: '';
    position: absolute;
    top: 0;
    left: -70px;
    width: 140px;
    height: 140px;
    border-radius: 50%;
    background: rgb(255, 20, 147);
    z-index: -1;
}

.heartShaped:after {
    top: -70px;
    left: 0;
}

气泡三角形

原理:利用 border 的 transparent 特性实现

 HTML:

<div class="bubbly">
    <p>heartShapedp>
div>

CSS:

.bubbly {
    position: absolute;
    top: 50%;
    left: 50%;
    transform: translate(-50%, -50%);
    background: #00aabb;
    border-radius: .4em;
    width: 260px;
    padding: 60px 20px;
    text-align: center;
    color: white;
    font-size: 200%;
}

.bubbly:after {
    content: '';
    position: absolute;
    bottom: 0;
    left: 50%;
    border: 34px solid transparent;

            padding: 60px 20px;
            text-align: center;
            color: white;
            font-size: 200%;
        }

        .notching {
            background: linear-gradient(135deg, transparent 15px, deeppink 0) top left, linear-gradient(-135deg, transparent 15px, deeppink 0) top right, linear-gradient(-45deg, transparent 15px, deeppink 0) bottom right, linear-gradient(45deg, transparent 15px, deeppink 0) bottom left;
            background-size: 50% 50%;
            background-repeat: no-repeat;
        }

弧形切角

<div class="arc">
    <p>arcp>
div>

CSS:

.arc {
    position: absolute;
    top: 50%;
    left: 50%;
    transform: translate(-50%, -50%);
    width: 60px;
    padding: 60px;
    text-align: center;
    color: white;
    font-size: 200%;
}

.arc {
    background: radial-gradient(circle at top left, transparent 15px, yellowgreen 0) top left, radial-gradient(circle at top right, transparent 15px, yellowgreen 0) top right, radial-gradient(circle at bottom right, transparent 15px, yellowgreen 0) bottom right, radial-gradient(circle at bottom left, transparent 15px, yellowgreen 0) bottom left;
