It is impossible to do this with CSS3 - even CSS3 image values and the replaced content module , although there is a lot of material related to gradients in it , allows you to use them where you could use the image, and not as a color.
However, SVG allows you to do this , although using this in HTML is a bit of work. First create an SVG document with gradient text. You will need a gradient:
<defs>
<linearGradient id="heading_gradient" x1="0%" y1="0%" x2="0%" y2="100%">
<stop offset="0%" style="stop-color:rgb(0,0,0); stop-opacity:1"/>
<stop offset="100%" style="stop-color:rgb(0,0,0); stop-opacity:0.1"/>
</linearGradient>
</defs>
And some text to apply it, pay attention to the attribute fill:
<text x="0" y="100"
font-family="sans-serif" font-weight="bold" fill="url(#heading_gradient)" >
<tspan font-size="100">A Big Heading</tspan>
</text>
Then you need to include SVG in your HTML.
<h1>
<object data="heading-fill.svg" type="image/svg+xml" height="125" width="800">
A Big Heading
</object>
</h1>
, SVG , , ( ). CSS, SVG :
h1 {
font-size: 100px;
font-family: sans-serif;
background-image: url('daisy-grass-repeating-background.jpg');
}
