Hello,
Sure, here you're:
$docx= new CreateDocx();
$html= '<p style="border: 2px solid black; color: red">A short text with a red border.</p>';
$rawWordML = $docx->embedHTML($html, array('rawWordML' => true, 'target' => 'defaultHeader'));
$html = $docx->createWordMLFragment(array($rawWordML));
$docx->addHeader(array('default' => $html));
$docx->createDocx('example_embedSimpleHTML');
Regards.
