Break out page to complete width

have you checked with another / default theme ?
sounds to me like perhaps some invalid html (missing a closing tag for example somewhere) or some css that overrides things specifically .

If it’s ok with you , I can make a test order on your site (it will be clearly marlked as such) and have a look

Hi Olly, sure thats good. Thanks for this quick and adequate reaction.

Best!

what’s (appears to be) happening is the following:
the order page containing the order page shortcode is wrapped in lots and lots of container elements (perhaps/probably by some pagebuilder plugin, though I cannot be certain )

The content of that page gets *replaced in its entirety* – after an order is made – with the order details.

As the surrounding page container in your theme/setup fills the whole page width, the order details will fill the whole width. There isn’t anything “breaking out” as it were.

However, you could target the so-called “thank you page” (for lack of a better description) layout using the “wppizza-order-wrap-thankyoupage” class to adjust / narrow this to your needs
(see also https://docs.wp-pizza.com/advanced/?section=frontend-css-styles-layout for some ideas as to application of custom css)

perhaps something like

.wppizza-order-wrap-thankyoupage{
max-width:1024px;
margin: 10px auto;
}

or whatever else you fancy

Thank you so much, quick and great answer. Thanks for the effort!

Best regards,

Remco
