Transparent text cut out of background
It's possible with css3 but it's not supported in all browsers
With background-clip: text; you can use a background for the text, but you will have to align it with the background of the page
body {
background: url(http://www.color-hex.com/palettes/26323.png) repeat;
margin:10px;
}
h1 {
background-color:#fff;
overflow:hidden;
display:inline-block;
padding:10px;
font-weight:bold;
font-family:arial;
color:transparent;
font-size:200px;
}
span {
background: url(http://www.color-hex.com/palettes/26323.png) -20px -20px repeat;
-webkit-text-fill-color: transparent;
-webkit-background-clip: text;
display:block;
}
<h1><span>ABCDEFGHIKJ</span></h1>

Automatic Alignment
With a little javascript you can align the background automatically:
$(document).ready(function(){
//Position of the header in the webpage
var position = $("h1").position();
var padding = 10; //Padding set to the header
var left = position.left + padding;
var top = position.top + padding;
$("h1").find("span").css("background-position","-"+left+"px -"+top+"px");
});
body {
background: url(http://www.color-hex.com/palettes/26323.png) repeat;
margin:10px;
}
h1 {
background-color:#fff;
overflow:hidden;
display:inline-block;
padding:10px;
font-weight:bold;
font-family:arial;
color:transparent;
font-size:200px;
}
span {
background: url(http://www.color-hex.com/palettes/26323.png) -20px -20px repeat;
-webkit-text-fill-color: transparent;
-webkit-background-clip: text;
display:block;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<h1><span>ABCDEFGHIKJ</span></h1>

There is a simple way to do this with just CSS:
background: black;
color: white;
mix-blend-mode: multiply;
for transparent text on a black background, or
background: white;
color: black;
mix-blend-mode: screen;
for transparent text on a white background.
Put these styles on your text element with whichever background you want behind it.
Example CodePen
Read up on mix-blend-mode
and experiment with it to use different colours.
Caveats:
- For this to work in chrome, you also need to explicitly set a background colour on the
html
element. - This works on basically all modern browsers except IE.
Although this is possible with CSS, a better approach would be to use an inline SVG with SVG masking. This approach has some advantages over CSS :
- Much better browser support: IE10+, chrome, Firefox, safari...
- This doesn't impact SEO as spiders can crawl SVG content (google indexes SVG content since 2010)
CodePen Demo : SVG text mask
body,html{height:100%;margin:0;padding:0;}
body{
background:url('https://farm9.staticflickr.com/8760/17195790401_94fcf60556_c.jpg');
background-size:cover;
background-attachment:fixed;
}
svg{width:100%;}
<svg viewbox="0 0 100 60">
<defs>
<mask id="mask" x="0" y="0" width="100" height="50">
<rect x="0" y="0" width="100" height="40" fill="#fff"/>
<text text-anchor="middle" x="50" y="18" dy="1">SVG</text>
<text text-anchor="middle" x="50" y="30" dy="1">Text mask</text>
</mask>
</defs>
<rect x="5" y="5" width="90" height="30" mask="url(#mask)" fill-opacity="0.5"/>
</svg>
If you aim on making the text selectable and searchable, you need to include it outside the <defs>
tag. The following example shows a way to do that keeping the transparent text with the <use>
tag:
body,html{height:100%;margin:0;padding:0;}
body{
background:url('https://farm9.staticflickr.com/8760/17195790401_94fcf60556_c.jpg');
background-size:cover;
background-attachment:fixed;
}
svg{width:100%;}
<svg viewbox="0 0 100 60">
<defs>
<g id="text">
<text text-anchor="middle" x="50" y="18" dy="1">SVG</text>
<text text-anchor="middle" x="50" y="30" dy="1">Text mask</text>
</g>
<mask id="mask" x="0" y="0" width="100" height="50">
<rect x="0" y="0" width="100" height="40" fill="#fff"/>
<use xlink:href="#text" />
</mask>
</defs>
<rect x="5" y="5" width="90" height="30" mask="url(#mask)" fill-opacity="0.5"/>
<use xlink:href="#text" mask="url(#mask)" />
</svg>
