css实现文字颜色渐变的几种方法

(推荐教程:CSS视频教程

在web前端开发过程中,UI设计师经常会设计一些带渐变文字的设计图,在以前我们只能用png的图片来代替文字,今天可以实现使用纯CSS实现渐变文字了。下面就介绍3中实现方式供大家参考!

基础样式:

.gradient-text {

    text-align: left;

    text-indent: 30px;

    line-height: 50px;

    font-size: 40px;

    font-weight: bolder;

    position: relative;

}

.gradient-text-one{ 

    background-image:-webkit-linear-gradient(bottom,red,#fd8403,yellow);

    -webkit-background-clip:text;

    -webkit-text-fill-color:transparent;

}

说明 :

  • background: -webkit-linear-gradient(...) 为文本元素提供渐变背景。

  • webkit-text-fill-color: transparent 使用透明颜色填充文本。

  • webkit-background-clip: text 用文本剪辑背景,用渐变背景作为颜色填充文本。

第二种方法,使用 mask-image

}

 

.gradient-text-two[data-content]::after {

    content: attr(data-content);

    display: block;

    position: absolute;

    color: yellow;

    left: 0;

    top: 0;

    z-index: 2;

    -webkit-mask-image: -webkit-gradient(linear, 0 0, 0 bottom,

                           from(yellow), to(rgba(0, 0, 255, 0)));

}

<svg viewBoxs="0 0 500 300" class="svgBox">

    <defs>

        <linearGradient id="SVGID_1_" gradientUnits="userSpaceOnUse" x1="0" y1="10" x2="0" y2="50">

            <stop  offset="0" style="stop-color:yellow"/>

            <stop  offset="0.5" style="stop-color:#fd8403"/>

            <stop  offset="1" style="stop-color:red"/>

        </linearGradient>

    </defs>

    <text text-anchor="middle" class="gradient-text-three" x="110px" y="30%">花信年华</text>

</svg>

说明:

在SVG中,有两种主要的渐变类型:

  • 线性渐变(linearGradient)

  • 放射性渐变(radialGradient)

SVG中的渐变不仅可以用于填充图形元素,还可以填充文本元素
