How to Change the Breakpoint in a WordPress Block Theme 

If you’ve worked with WordPress block themes, you’ve probably noticed that the default breakpoints don’t always align with your design needs. While the default settings work for most scenarios, there are times when you need to tweak them to match your project’s specific requirements—especially if you’re aiming for a more custom, responsive design. 

In my case, I needed to adjust the navigation block’s breakpoint. Out of the box, WordPress decides when the menu switches to the “hamburger” style based on its default breakpoint, but I wanted more control over when that switch happens. 

Customizing the Navigation Block Breakpoint 

To adjust the navigation block’s breakpoint, you’ll need a bit of custom CSS. Specifically, you can target the classes used by the WordPress navigation block to modify its behavior. Below is the CSS I used to change the breakpoint: 

/* CHANGE NAV BREAKPOINT */ 
.wp-block-navigation__responsive-container-open:not(.always-shown) { 
    display: block !important; 
} 
 
.wp-block-navigation__responsive-container:not(.hidden-by-default):not(.is-menu-open) { 
    display: none !important; 
} 
 
/* Change the navigation breakpoint to 1199px */ 
@media (min-width: 1199px) { 
 
    .wp-block-navigation__responsive-container-open:not(.always-shown) { 
        display: none !important; 
    } 
 
    .wp-block-navigation__responsive-container:not(.hidden-by-default):not(.is-menu-open) { 
        display: block !important; 
    } 
} 

When working on customizations like this, make sure to test your changes. Check how your navigation behaves on different devices and screen sizes. The goal is to ensure the menu transitions smoothly and remains user-friendly. 

Adjusting breakpoints might seem like a small change, but it can have a big impact on your site’s responsiveness and usability. I hope this article helps.
