Hi Kym,
Thanks so much for reaching out with your BoldGrid Post and Page Builder questions!
I’m sorry to hear you’re having some issues with mobile responsiveness. Post and Page Builder allows you to set conditions for which blocks and elements appear on the page, depending on the size of the screen.
By default, all elements are visible on all devices but you can use the responsive utilities in Post and Page Builder to hide specific elements. This allows you to easily build out your WordPress site with a mobile first design approach.
You may also benefit from reviewing this comprehensive guide on using the Post and Page Builder in general.
If you let us know what exactly what issues you’re experiencing with mobile responsiveness and we will help you to tackle them one by one.
I hope this helps Kym! We’re always here if you have any other questions for us.
