根据宽度百分比裁剪CSS线性渐变

问题描述

我在进度条上应用了的线性渐变。问题在于，即使百分比较低或较高，渐变也是相同的。

我想要实现的是，百分比越多，它应该变得更正确。 因此，换句话说，完整渐变应为100％，而对于50％，仅应显示渐变的50％。我不想创建多个渐变来解决此问题，而是尝试使用剪切路径解决此问题，但没有成功。任何帮助将不胜感激。

这是我当前的代码 https://codepen.io/taimursaeed/pen/gOrLNyv

body {
  font-size: 30px;
}

.progress-custom {
  display: flex;
  align-items: center;
  margin-bottom: 0.5em;
}

.progress {
  display: flex;
  height: 1rem;
  overflow: hidden;
  font-size: 0.75rem;
  background-color: #e9ecef;
  border-radius: 0.25rem;
  height: 3em;
  font-size: 0.6em;
  flex: 1;
}

.progress-bar {
  display: flex;
  flex-direction: column;
  justify-content: center;
  overflow: hidden;
  color: #fff;
  text-align: center;
  white-space: nowrap;
  background-color: #007bff;
  transition: width 0.6s ease;
  background: linear-gradient(90deg,#ff9800 0%,#ff5722 100%);
}

.progress-custom .progress-value {
  font-size: 0.8em;
  padding: 0 0.5em;
}

<div class="progress-custom">
  <div class="progress">
    <div role="progressbar" aria-valuenow="70" aria-valuemin="0" aria-valuemax="100" class="progress-bar" style="width: 70%;">
      My Progress
    </div>
  </div>
  <span class="progress-value"> 70%</span>
</div>
<div class="progress-custom">
  <div class="progress">
    <div role="progressbar" aria-valuenow="50" aria-valuemin="0" aria-valuemax="100" class="progress-bar" style="width: 50%;">
      My Progress
    </div>
  </div>
  <span class="progress-value"> 50%</span>
</div>
<div class="progress-custom">
  <div class="progress">
    <div role="progressbar" aria-valuenow="20" aria-valuemin="0" aria-valuemax="100" class="progress-bar" style="width: 20%;">
      My Progress
    </div>
  </div>
  <span class="progress-value"> 20%</span>
</div>

解决方法

在.progress-bar上添加一行

.progress-bar{ background-attachment: fixed}

我相信，为获得引人注目的效果，颜色应更加多样化-取决于闪电，相似的颜色可能看起来相同。
在代码段中，我更改了它们-根据您自己的喜好使用颜色，而不是我的：）

div{
box-sizing: border-box;
margin: 20px auto 20px 0;
padding: 20px;
color: #fff;
text-align: center;
background: linear-gradient(to right,gold,red);
background-attachment: fixed}

<div style="width: 20%;">20%</div>
<div style="width: 50%;">50%</div>
<div style="width: 70%;">70%</div>
<div style="width: 99%;">99%</div>

看看我的片段。您的渐变具有两种几乎相同的颜色，并且差别不大，因为颜色太相似了。

想到了另一个选择-具有透明度的渐变：

background: linear-gradient(to right,rgba(200,200,0.2),rgba(255,1.0));

,

我使用了clip-path和padding-right。我没有使用伪元素或多余元素。

body {
  font-size: 30px;
  width: 350px;
  margin: 50px auto;
}

.progress-custom {
  display: flex;
  align-items: center;
  margin-bottom: 0.5em;
}

.progress {
  display: flex;
  height: 1rem;
  overflow: hidden;
  font-size: 0.75rem;
  background-color: #e9ecef;
  border-radius: 0.25rem;
  height: 3em;
  font-size: 0.6em;
  flex: 1;
  position: relative;
}

.progress-bar {
  display: flex;
  flex-direction: column;
  justify-content: center;
  overflow: hidden;
  color: #fff;
  text-align: center;
  white-space: nowrap;
  transition: width 0.6s ease;
  overflow: hidden;
  background: linear-gradient(to right,red);
  padding-right:calc(100% - var(--width));
  width: 100%;
  height: 100%;
  -webkit-clip-path: inset(0 calc(100% - var(--width)) 0 0);
  clip-path: inset(0 calc(100% - var(--width)) 0 0);
}

.progress-custom .progress-value {
  font-size: 0.8em;
  padding: 0 0.5em;
}

<div class="progress-custom">
  <div class="progress">
    <div role="progressbar" aria-valuenow="70" aria-valuemin="0" aria-valuemax="100" class="progress-bar" style="--width: 70%;">
      My Progress
    </div>
  </div>
  <span class="progress-value"> 70%</span>
</div>
<div class="progress-custom">
  <div class="progress">
    <div role="progressbar" aria-valuenow="50" aria-valuemin="0" aria-valuemax="100" class="progress-bar" style="--width: 50%;">
      My Progress
    </div>
  </div>
  <span class="progress-value"> 50%</span>
</div>
<div class="progress-custom">
  <div class="progress">
    <div role="progressbar" aria-valuenow="20" aria-valuemin="0" aria-valuemax="100" class="progress-bar" style="--width: 20%;">
      My Progress
    </div>
  </div>
  <span class="progress-value"> 20%</span>
</div>

您可以使用background-clip和padding来解决此问题，如下所示：

body {
  font-size: 30px;
}

.progress-custom {
  display: flex;
  align-items: center;
  margin-bottom: 0.5em;
}
.progress-custom > div:first-child {
  flex:1;
}

.progress-bar {
  display: flex;
  justify-content: center;
  align-items:center;
  border-radius: 0.25rem;
  height: 3em;
  font-size: 0.6em;
  color: #fff;
  transition: padding 0.6s ease;
  padding-right:calc(100% - var(--p));
  background: 
    /* show the gradient on the content only but use the padding area for the calculation */
    linear-gradient(90deg,#ff9800 0%,#ff5722 100%) padding-box content-box,#e9ecef;
}

.progress-custom .progress-value {
  font-size: 0.8em;
  padding: 0 0.5em;
}

<div class="progress-custom">
  <div>
    <div role="progressbar" aria-valuenow="70" aria-valuemin="0" aria-valuemax="100" class="progress-bar" style="--p:70%;">
      My Progress
    </div>
  </div>
  <span class="progress-value"> 70%</span>
</div>
<div class="progress-custom">
  <div>
    <div role="progressbar" aria-valuenow="50" aria-valuemin="0" aria-valuemax="100" class="progress-bar" style="--p:50%">
      My Progress
    </div>
  </div>
  <span class="progress-value"> 50%</span>
</div>
<div class="progress-custom">
  <div>
    <div role="progressbar" aria-valuenow="20" aria-valuemin="0" aria-valuemax="100" class="progress-bar" style="--p:20%">
      My Progress
    </div>
  </div>
  <span class="progress-value"> 20%</span>
</div>

使用剪切路径和伪元素的另一个想法：

body {
  font-size: 30px;
}

.progress-custom {
  display: flex;
  align-items: center;
  margin-bottom: 0.5em;
}
.progress-custom > div:first-child {
  flex:1;
  position:relative; /* the pseudo element will be relative to this div */
  background:#e9ecef;
  z-index:0;
}

.progress-bar {
  display: flex;
  justify-content: center;
  align-items:center;
  border-radius: 0.25rem;
  height: 3em;
  font-size: 0.6em;
  color: #fff;
  transition: width 0.6s ease;
  width:var(--p);
  clip-path:inset(0); /* hide the non needed part*/
}
.progress-bar::before {
  content:"";
  position:absolute;
  z-index:-1;
  top:0;
  left:0;
  right:0;
  bottom:0;
  background: linear-gradient(90deg,#ff5722 100%);
}

.progress-custom .progress-value {
  font-size: 0.8em;
  padding: 0 0.5em;
}

<div class="progress-custom">
  <div>
    <div role="progressbar" aria-valuenow="70" aria-valuemin="0" aria-valuemax="100" class="progress-bar" style="--p:70%;">
      My Progress
    </div>
  </div>
  <span class="progress-value"> 70%</span>
</div>
<div class="progress-custom">
  <div>
    <div role="progressbar" aria-valuenow="50" aria-valuemin="0" aria-valuemax="100" class="progress-bar" style="--p:50%">
      My Progress
    </div>
  </div>
  <span class="progress-value"> 50%</span>
</div>
<div class="progress-custom">
  <div>
    <div role="progressbar" aria-valuenow="20" aria-valuemin="0" aria-valuemax="100" class="progress-bar" style="--p:20%">
      My Progress
    </div>
  </div>
  <span class="progress-value"> 20%</span>
</div>
