<p class="rainbowtext">Hello! This should have rainbow coloring.</p>

我想制作一个彩虹色的文字。此代码工作正常，但只有Safari / Chrome，在Firefox中文本是透明的。我试过乱搞它没有成功。任何帮助：P？

使用SVG在Yoksel的codepen上找到一个解决方案，使用彩虹渐变绘制200x200图案，然后将其作为填充应用于文本。

<div class="wrapper">
  <svg  width="350" height="25">
    <defs>
        <linearGradient id="rainbowGradient" x1="0" y1="0" x2="100%" y2="0%"> <!--20% spreadMethod="repeat"-->
          <stop offset="0%" stop-color="crimson" /><stop offset="10%" stop-color="purple" />
          <stop offset="10%" stop-color="red" /><stop offset="20%" stop-color="crimson" />
          <stop offset="20%" stop-color="orangered" /><stop offset="30%" stop-color="red" />
          <stop offset="30%" stop-color="orange" /><stop offset="40%" stop-color="orangered" />
          <stop offset="40%" stop-color="gold" /><stop offset="50%" stop-color="orange" />
          <stop offset="50%" stop-color="yellowgreen" /><stop offset="60%" stop-color="gold" />
          <stop offset="60%" stop-color="green" /><stop offset="70%" stop-color="yellowgreen" />
          <stop offset="70%" stop-color="steelblue" /><stop offset="80%" stop-color="skyblue" />
          <stop offset="80%" stop-color="mediumpurple" /><stop offset="90%" stop-color="steelblue" />
          <stop offset="90%" stop-color="purple" /><stop offset="100%" stop-color="mediumpurple" />
        </linearGradient>
      
        <pattern id="rainbow" 
                 patternUnits="userSpaceOnUse"
                 width="200" height="200" 
                 viewbox="0 0 200 200">
          <rect width="200" height="200"
                  fill="url(#rainbowGradient)"/>
        </pattern>
      </defs>
  
    <text x="0" y="50%" style="fill: url(#rainbow);">Hello! This has have rainbow coloring.</text>
  </svg>
</div>

修改

具有讽刺意味的是，我在这里使用ff，所以我误解了你的问题。

你正在使用的这个效果是webkit独有的，firefox上没有对应-webkit-background-clip: text;
