实现成果

1.什么是conic-gradient(圆锥突变)

conic-gradient是圆锥突变,以一个点为核心起始点,沿着圆周变动。
语法:conic-gradient( from 起始角度 at 中心点地位, 突变断点 )
兼容性:

一个简略的例子:看清他的突变方向,起始点是图形核心,而后以顺时针方向绕核心实现突变成果。

<style>         section{            margin: 40px auto;            display: flex;            flex-direction: column;            align-items: center;            justify-content: center;        }                    .a{            background:conic-gradient(#000, #fff);            width: 200px;            height: 200px;        }    </style>    <body>        <section>            <h1>一个简略的例子</h1>            <div class="a"></div>        </section>    </body>

2.linear-gradient : 线性突变

linear-gradient 线性突变的方向是一条直线,能够是任何角度,向下/向上/向左/向右/对角方向。看一个简略的例子。repeating-linear-gradient()示意反复的线性突变。
语法:background-image: linear-gradient(direction, color-stop1, color-stop2, ...);
为了创立一个线性突变,你必须至多定义两种色彩节点。色彩节点即你想要出现平稳过渡的色彩。同时,你也能够设置一个终点和一个方向(或一个角度)。

<section>    <h1>一个简略的例子linear-gradient</h1>    <div class="b"></div></section><section>    <h1>一个例子repeating-linear-gradient</h1>    <div class="c"></div></section>.b{    background:linear-gradient(to top right ,red 0,yellow 50%,transparent 50%,transparent 100%);    width: 200px;    height: 200px;}.c{    background:repeating-linear-gradient(45deg,#55aa7f,#55ff7f,5px ,#ffaaff 0,#ff55ff  20px);    width: 200px;    height: 200px;}

3.radial-gradient : 径向突变

径向突变是从圆心点以椭圆形状向外扩散。
语法:background-image: radial-gradient(shape size at position, start-color, ..., last-color);
shape 参数定义了形态。它能够是值 circle 或 ellipse。其中,circle 示意圆形,ellipse 示意椭圆形。默认值是 ellipse。

<section>    <h1>一个例子radial-gradient</h1>    <div class="d"></div></section><section>    <h1>一个例子radial-gradient椭圆形 Ellipse(默认):</h1>    <div class="e"></div></section><section>    <h1>一个例子radial-gradient圆形 Circle:</h1>    <div class="f"></div></section>.d{    background-image:radial-gradient(transparent 0,transparent 49%,#ffaaff 50%,#3eff8b 100%);    width: 200px;    height: 200px;}.e{    background-image:radial-gradient(#ffaaff ,#3eff8b,#000);    width: 300px;    height: 200px;}.f{    background-image:radial-gradient(circle,#ffaaff ,#3eff8b,#000);    width: 300px;    height: 200px;}

3.1反复的径向突变

repeating-radial-gradient() 函数用于反复径向突变。

<section>    <h1>一个反复的radial-gradient</h1>    <div class="g"></div></section>.g{        width: 300px;        height: 200px;        background-image: repeating-radial-gradient(#ffaaff 10% ,#3eff8b 20%,#000 10%);    }

4.重点的说一下conic-gradient(锥形突变的利用)

.j{    background:conic-gradient(red, orange, yellow, green, teal, blue, purple,red);    width: 200px;    height: 200px;    border-radius: 50%;}<section>    <h1>conic-gradient实现色彩表盘</h1>    <div class="j"></div></section>

4.2圆环进度条

<section>    <h1>conic-gradient实现圆弧进度条成果</h1>    <div class="n" style="background-image:conic-gradient(from -180deg,#a8c992 77%,#ebebeb 0%)">        <text class="n-text">77%</text>    </div></section>.n{    width: 200px;    height: 200px;    border-radius: 50%;    position: relative;}.n::before {  content: "";  position: absolute;  left: 50%;  top: 50%;  transform: translate(-50%, -50%);  width: 90%;  height: 90%;  border-radius: 50%;  background-color: #fff;}.n-text{  position: absolute;  left: 50%;  top: 50%;  transform: translate(-50%, -50%);  font-size: 20rpx;  color: #a8c992;}
