How can I add line breaks and hyphens to my Prestige theme?

[MoritzRuschen]

Hello all, 

I would like to add line breaks and hyphens to my Shopify theme, Prestige. I have already crafted a CSS code snippet that achieves this; however, Shopify is preventing me from publishing it. The issue seems to be with the `hyphen` attribute, which is being blocked within this section of the code.

Do you have any suggestions or solution?

@media (max-width: 699px) {
p {
text-align: justify !important;
hyphens: auto; /* Aktiviert die automatische Silbentrennung */
}
}

Thanks in advance, would really appreciate any help...

Edit: The Problem also occurs by using the shopify theme Dawn.
