您可以在多个背景下执行此操作。
从0%到50%:
.box {
width: 100px;
height: 100px;
display: inline-block;
border-radius: 50%;
border: 5px solid transparent;
background:
linear-gradient(#ccc, #ccc) padding-box,
linear-gradient(var(--v), #f2f2f2 50%, transparent 0) border-box,
linear-gradient(to right, #f2f2f2 50%, blue 0) border-box;
}
<div class="box" style="--v:-90deg"></div><!-- 0% -->
<div class="box" style="--v:-45deg"></div><!-- 12.5% -->
<div class="box" style="--v: 0deg"></div><!-- 25% -->
<div class="box" style="--v: 45deg"></div><!-- 37.5% -->
<div class="box" style="--v: 90deg"></div><!-- 50% -->
<p>The formula is [p = (18/5) * x - 90]. <small>Where x is the percentage and p the degree</small></p>
<p>for x = 5% --> p = -72deg </p>
<div class="box" style="--v:-72deg"></div>
从50%到100%:
.box {
width:100px;
height:100px;
display:inline-block;
border-radius:50%;
border:5px solid transparent;
background:
linear-gradient(#ccc,#ccc) padding-box,
linear-gradient(var(--v), blue 50%,transparent 0) border-box,
linear-gradient(to right, #f2f2f2 50%,blue 0) border-box;
}
<div class="box" style="--v:-90deg"></div><!-- 50% -->
<div class="box" style="--v:-45deg"></div><!-- 62.5% -->
<div class="box" style="--v: 0deg"></div><!-- 75% -->
<div class="box" style="--v: 45deg"></div><!-- 87.5% -->
<div class="box" style="--v: 90deg"></div><!-- 100% -->
<p>The formula is [p = (18/5) * x - 270]. <small>Where x is the percentage and p the degree</small></p>
<p>for x = 80% --> p = 18deg </p>
<div class="box" style="--v:18deg"></div>
您可以像这样组合两者:
.box {
width:100px;
height:100px;
display:inline-block;
border-radius:50%;
border:5px solid transparent;
background:
linear-gradient(#ccc,#ccc) padding-box,
linear-gradient(var(--v), #f2f2f2 50%,transparent 0) center/calc(var(--s)*100%) border-box,
linear-gradient(var(--v), blue 50%,transparent 0) center/calc(100% - var(--s)*100%) border-box,
linear-gradient(to right, #f2f2f2 50%,blue 0) border-box;
}
<div class="box" style="--v:-90deg;--s:1"></div>
<div class="box" style="--v:0deg;--s:1"></div>
<div class="box" style="--v:90deg;--s:1"></div>
<div class="box" style="--v:0deg;--s:0"></div>
<div class="box" style="--v:90deg;--s:0"></div>

使用新的圆锥体渐变,可以使用一个div来进行管理,该div刚刚作为实验属性进入Chrome浏览器。
:root {
--size: 100px;
--bord: 10px;
}
.chart {
width: var(--size);
height: var(--size);
margin: 1em auto;
border-radius: 50%;
background-image: conic-gradient(lightseagreen var(--value), lightgrey var(--value));
position: relative;
display: flex;
justify-content: center;
align-items: center;
}
.chart::after {
content: "";
position: absolute;
left: 50%;
top: 50%;
transform: translate(-50%, -50%);
width: calc(100% - var(--bord));
height: calc(100% - var(--bord));
background: white;
border-radius: inherit;
}
p {
position: relative;
z-index: 1;
font-size: 2em;
}
.x-60 {
--value: 60%;
}
.x-20 {
--value: 20%;
}
<div class="chart x-60">
<p>60%</p>
</div>
<div class="chart x-20">
<p>20%</p>
</div>
多亏了Temani Afif,可以在没有使用边框和伪造元素的伪元素的情况下实现此目标background-clip。
background:
linear-gradient(white,white) padding-box,
conic-gradient(lightseagreen var(--value), lightgrey var(--value)) border-box;
:root {
--size: 100px;
--bord: 10px;
}
.chart {
width: var(--size);
height: var(--size);
margin: 1em auto;
border: var(--bord) solid transparent;
border-radius: 50%;
background: linear-gradient(white, white) padding-box, conic-gradient(lightseagreen var(--value), lightgrey var(--value)) border-box;
position: relative;
display: flex;
justify-content: center;
align-items: center;
font-size: 2em;
}
.x-60 {
--value: 60%;
}
.x-20 {
--value: 20%;
}
<div class="chart x-60">
<p>60%</p>
</div>
<div class="chart x-20">
<p>20%</p>
</div>
