Can't use @page or something similar - Goal is to use a class for only the first page

In general all css rules are working but I can't define css, that should work only for the first page.

Is there any workaround?

Thanks and regards

You are correct that @page supports limited styling options. What type of styling are you attempting to apply only to the first page?

Super simple, I want to give a div container "display: none;" and this only at the first page.

That is challenging with current feature support, but not impossible. It has to be done outside the document through callbacks. I think something like the following might work (untested, unoptimized):

$dompdf->setCallbacks([
    [
        'event' => 'begin_frame',
        'f' => function ($frame, $canvas, $fontMetrics) {
            $node = $frame->get_node();
            if ($node->hasAttributes() && ($id = $node->attributes->getNamedItem("id")) !== null && $id->nodeValue === "myid") {
                $style = $frame->get_style();
                if ($canvas->get_page_number() === 1) {
                    $style->set_used("display", "none");
                } else {
                    $style->set_used("display", "block");
                }
            }
        }
    ]
]);

There is a request to make @page usable as a selector (#1486), though there is no movement on that request at this time.

@bsweeney Where to place the class name?

[bsweeney]

Sorry I left something out, sample updated. If you're identifying by the class attribute instead use getNamedItem("class")

Sadly it didn't worked out.

If you share a sample of the HTML and PHP you tried I can try to figure out why not.
