Case Study: Global CSS Override for WPBakery Pages

The Problem

A website with over 300 pages was built using WPBakery Page Builder. A global CSS rule had been added and applied across every page, forcing all h2 and h3 headings to display in bold and a specific color using !important.

This created a major limitation: heading styles could not be adjusted within WPBakery, as the global rule overrode all page-level customizations. Manually updating each page was not a practical solution due to the scale of the site.

The Solution

To resolve this efficiently, a global override was implemented using a WordPress action hook. A custom function was added code snippet, injecting targeted CSS into the site header.

This override specifically targeted WPBakery content containers and reset the heading styles to normal font weight and inherited color. By using !important strategically, the new rule successfully overrode the existing global CSS without modifying individual pages.

Code Implementation

				
					function override_heading_styles() {
    if (!is_admin()) {
        echo '<style>
            .vc_row h2,
            .vc_row h3 {
                font-weight: normal !important;
                color: inherit !important;
            }
        </style>';
    }
}
add_action('wp_head', 'override_heading_styles', 100);

The Results

Successfully restored flexible heading styling across all WPBakery pages
Eliminated the need to manually edit 300+ pages
Reduced development time significantly
Improved maintainability and scalability of the website’s styling system

This solution demonstrates an efficient approach to handling large-scale CSS conflicts using WordPress hooks and targeted overrides.
