By default, the Sydney theme applies a full-height layout to pages, making them stretch to at least the height of the browser viewport (100vh). This avoids awkward spaces after the footer in case your page content doesn’t have enough height, but in some cases you may want to disable it for custom designs or compatibility reasons.
To disable this behaviour, you can use a custom code plugin like WPCode and add this filter:
/**
* Disable full-height pages in Sydney theme
*/
add_filter( 'sydney_enable_page_min_height', '__return_false' );If you are an existing user and would like to enable this feature, simply add the following code using the WPCode plugin:
set_theme_mod( 'sydney_enable_page_min_height', true );
