如何自定义Wordpress主题标题以更改布局？

I am using the latest version of the Avada theme. I would like to place full-width content (a simple shortcode) in the header area of a page that has sidebars enabled. However, I have found that the theme does not allow you to have full-width content (aside from built-in options like the slide, menu, artwork, etc.), with a page that has sidebars enabled.

A moderator on their user forum wrote this in regards to this limitation:

Going by your screenshot you will have to create a custom solution for that. (referring to the full width section above the page and sidebar content, based on your screenshot) – that would mean creating a std page in WP and then in the header file using PHP to call that page and it's content into position:

    <?php if ( is_front_page() ) { $subPageHeader = new WP_Query("page_id=25″); >while($subPageHeader->have_posts()) : $subPageHeader->the_post(); ?>

This is just a head start.

Here is the screenshot he's referring to: http://i.stack.imgur.com/jHRdn.jpg

The four content items: Our Issues, Our Contract, Opportunities, Q&A is what I'm trying to add.

Unfortunately I only got a partial explanation and am humbly asking for the community's help on achieving this. Thanks in advance.

As the moderator said you can make other page and design it as you want and call it into your header.php . It's so simple just make your page by .php format witch it start with:

<?php

and ends with:

?>

then call it like this:

<?php get_template_directory_uri(); ?>

or

<?php echo get_template_directory_uri(); ?>

or even you can call it by functions.php like this:

<?php
function my_scripts_method() {
    wp_enqueue_script(
        'custom_script',
        get_template_directory_uri() . '/js/custom_script.js',
        array('jquery')
    );
}
add_action('wp_enqueue_scripts', 'my_scripts_method');
?>

Just remember to do not call header and footer into your page cause you no want double header into each other.
