What are some common pitfalls when converting HTML with CSS to a PDF using dompdf in PHP?

One common pitfall when converting HTML with CSS to a PDF using dompdf in PHP is that certain CSS properties or selectors may not be fully supported by dompdf, leading to unexpected rendering issues in the PDF output. To address this, it's important to review dompdf's documentation on supported CSS properties and selectors, and adjust the HTML and CSS accordingly to ensure compatibility.

// Example code snippet demonstrating how to adjust CSS properties for dompdf compatibility
$html = '<html><head><style>
            body {
                font-family: Arial, sans-serif; /* Use web-safe fonts */
            }
            .content {
                width: 100%; /* Make sure content fits within PDF page */
            }
        </style></head><body>
        <div class="content">
            <h1>Hello, World!</h1>
            <p>This is a sample PDF generated using dompdf.</p>
        </div>
        </body></html>';

require_once 'dompdf/autoload.inc.php';
use Dompdf\Dompdf;

$dompdf = new Dompdf();
$dompdf->loadHtml($html);
$dompdf->render();
$dompdf->stream('sample.pdf');
