Align center 404 page text and add text to a button

Hi there,

Try this CSS:

.error404 h1.entry-title {
    text-align: center;
}

Adding CSS: https://docs.generatepress.com/article/adding-css/

and this PHP:

add_filter( 'generate_search_button','generate_custom_search_button' );
function generate_custom_search_button()
{
	return 'Search';
}

Adding PHP: https://docs.generatepress.com/article/adding-php/

Hello again,

I could align the text but the button doesn't work. I pasted the second code on my punctions.php of my child theme.

Try this CSS instead:

.error404 .search-submit:before {
    content: "Search";
}

.error404 .search-submit .gp-icon {
    display: none;
}

Bingo!

Thanks!

No problem :)
