WordPress : Genesis Framework add Class - wordpress

Question

Are you able to add classes to the genesis themes structure?
For example:
do_action('genesis_before_header');
do_action('genesis_header');
do_action('genesis_after_header');
Where are these functions initialised and where can I add to them or create my own?

Answer 1

Example do_action( 'genesis_header' );, if you wish to change the class of your header or HTML mark up for example, use this codes.
THIS IS THE DEFAULT STRUCTURE
add_action( 'genesis_header', 'genesis_header_markup_open', 5 );
function genesis_header_markup_open() {
genesis_markup( array(
'html5' => '<header %s>',
'xhtml' => '<div id="header">',
'context' => 'site-header',
) );
genesis_structural_wrap( 'header' );
}
function genesis_header_markup_close() {
genesis_structural_wrap( 'header', 'close' );
genesis_markup( array(
'html5' => '</header>',
'xhtml' => '</div>',
) );
}
add_action( 'genesis_header', 'genesis_header_markup_close', 15 );
THIS IS YOUR CUSTOM STRUCTURE
remove_action( 'genesis_header', 'genesis_header_markup_open', 5 );
remove_action( 'genesis_header', 'genesis_header_markup_close', 15 );
add_action( 'genesis_header', 'genesis_header_markup_open_custom', 5 );
function genesis_header_markup_open_custom() {
genesis_markup( array(
'html5' => '<div %s>',
'xhtml' => '<div id="my-header">',
'context' => 'my-header',
) );
genesis_structural_wrap( 'header' );
}
function genesis_header_markup_close_custom() {
genesis_structural_wrap( 'header', 'close' );
genesis_markup( array(
'html5' => '</div>',
'xhtml' => '</div>',
) );
}
add_action( 'genesis_header', 'genesis_header_markup_close_custom', 15 );
Or simply add a custom function that contains your custom HTML mark-up and classes. Use this
add_action( 'genesis_header', 'opening', 6 );
add_action( 'genesis_header', 'closing', 14 );
function opening(){
echo '<div class="opening">'; //Opening div element
}
function closing(){
echo '</div>'; //Closing div element
}
Output
To know where is the genesis structure located, visit this folder
theme/genesis/genesis/lib/structure
Hope this will help.

If you just need a body class on a particular template, try
//* Add custom body class to the head
add_filter( 'body_class', 'my_body_class' );
function my_body_class( $classes ) {
$classes[] = 'YOUR-CLASS-HERE';
return $classes;
}
