# QRMarkupHTML
|
||
|
||
[Class `QRMarkupHTML`](https://github.com/chillerlan/php-qrcode/blob/main/src/Output/QRMarkupHTML.php): HTML output
|
||
|
||
This class is a cheap markup substitute for when SVG is not available or not an option (which was an issue before ca 2012).
|
||
As a general rule: if you plan to display the QR Code in a web browser, you should be using the [SVG output](../Built-In-Output/QRMarkupSVG.md).
|
||
|
||
|
||
## Example
|
||
|
||
See: [HTML example](https://github.com/chillerlan/php-qrcode/blob/main/examples/html.php)
|
||
|
||
Set the options:
|
||
|
||
```php
|
||
$options = new QROptions;
|
||
|
||
$options->outputInterface = QRMarkupHTML::class;
|
||
$options->cssClass = 'qrcode';
|
||
$options->moduleValues = [
|
||
// finder
|
||
QRMatrix::M_FINDER_DARK => '#A71111', // dark (true)
|
||
QRMatrix::M_FINDER_DOT => '#A71111', // finder dot, dark (true)
|
||
QRMatrix::M_FINDER => '#FFBFBF', // light (false)
|
||
// alignment
|
||
QRMatrix::M_ALIGNMENT_DARK => '#A70364',
|
||
QRMatrix::M_ALIGNMENT => '#FFC9C9',
|
||
];
|
||
```
|
||
|
||
Output in a HTML document (via PHP):
|
||
|
||
```php
|
||
<?php
|
||
|
||
$data = 'https://www.youtube.com/watch?v=dQw4w9WgXcQ';
|
||
$out = new QRCode($options)->render($data);
|
||
|
||
header('Content-type: text/html');
|
||
|
||
?>
|
||
<!DOCTYPE html>
|
||
<html lang="none">
|
||
<head>
|
||
<meta charset="UTF-8"/>
|
||
<meta name="viewport" content="width=device-width, initial-scale=1.0"/>
|
||

|
||
<style>
|
||
div.qrcode{
|
||
margin: 1em;
|
||
}
|
||
|
||
/* rows */
|
||
div.qrcode > div {
|
||
height: 10px;
|
||
}
|
||
|
||
/* modules */
|
||
div.qrcode > div > span {
|
||
display: inline-block;
|
||
width: 10px;
|
||
height: 10px;
|
||
}
|
||
</style>
|
||
</head>
|
||
<body>
|
||
<!-- php poutput -->
|
||
<?php echo $out; ?>
|
||
</body>
|
||
</html>
|
