Some improvements if possible

Hi there,

1. You can move your Language Widget to the Top bar widget area.
To display the current date - Tom provides the code to create a shortcode here:

https://generatepress.com/forums/topic/shortcode-for-current-date/#post-632065

You can use that to add the date to a HTML widget in the top bar.

2. and 3. You can add use the Hook Element to insert content into the site:

The after_header hook can be used to place elements after your site header and navigation.

Hi David, When i put the clock code on 'CSS aditional' all code letters stay red

Sorry for the my last comment.

David i put the code

add_shortcode( 'custom_date', function() {
$time_string = '<time class="entry-date published" datetime="%1$s" itemprop="datePublished">%2$s</time>';

if ( get_the_time( 'U' ) !== get_the_modified_time( 'U' ) ) {
$time_string .= '<time class="updated" datetime="%3$s" itemprop="dateModified" style="display:none;">%4$s</time>';
}

$time_string = sprintf( $time_string,
esc_attr( get_the_date( 'c' ) ),
esc_html( get_the_date() ),
esc_attr( get_the_modified_date( 'c' ) ),
esc_html( get_the_modified_date() )
);

$date = sprintf( '%3$s',
esc_url( get_permalink() ),
esc_attr( get_the_time() ),
$time_string
);

return $date;
} );

in the HTML Widget and nothing happens.

Say 'Please use tab for identation'.

That code is PHP.
It goes in either your Child Theme functions.php or use the Code Snippets plugin.
More info:
https://docs.generatepress.com/article/adding-php/

Once that is added you add this to your widget:

[custom_date]

David, when i put the php code on a create plugin and activate it a message say 'Fatal error'.

Install the Code Snippets plugin:

https://en-gb.wordpress.org/plugins/code-snippets/

And Copy the code from here:

https://generatepress.com/forums/topic/shortcode-for-current-date/#post-632065

Then paste the code in Code Snippets

I have problem David, once i installed this program and i puted a code when activated i must to recover the site because a fatal error appear, since then always i install the Code Snippets plugin and activate it a fatal error occurs.

I use Pluginception
