CSS would be an easy option. * Let me know 🙂 * Thread Starter [Stefano](https://wordpress.org/support/users/stefacchio/) * (@stefacchio) * [1 year, 11 months ago](https://wordpress.org/support/topic/set-global-max-width-by-code-for-custom-theme/#post-17847319) * I mean to set the global max-width value into GB Settings sections. I wanna keep a universal place where set this value, at the moment I have a custom option in WP Customizer to set it. * Maybe can I set global max-width with some code in functions.php by first retrieving the value from the customiser and then injecting it into generateblock? * Thanks - This reply was modified 1 year, 11 months ago by [Stefano](https://wordpress.org/support/users/stefacchio/). * Plugin Support [ying](https://wordpress.org/support/users/yingscarlett/) * (@yingscarlett) * [1 year, 11 months ago](https://wordpress.org/support/topic/set-global-max-width-by-code-for-custom-theme/#post-17847348) * I actually don’t quite get your idea. The max-width is not an essential attribute for GB blocks, we adds that only when it’s needed. * However, GB has the global max-width option at dashboard> generateblocks > settings. * Let me know if that works for you. * Thread Starter [Stefano](https://wordpress.org/support/users/stefacchio/) * (@stefacchio) * [1 year, 11 months ago](https://wordpress.org/support/topic/set-global-max-width-by-code-for-custom-theme/#post-17847364) * it’s very usefull because with a max width wrapper set on the theme, when I use a full width block/container and an inner container, to keep the same width of the template theme, it’s necessary set the max width on inner container. * Plugin Support [ying](https://wordpress.org/support/users/yingscarlett/) * (@yingscarlett) * [1 year, 11 months ago](https://wordpress.org/support/topic/set-global-max-width-by-code-for-custom-theme/#post-17847498) * So it works? * Thread Starter [Stefano](https://wordpress.org/support/users/stefacchio/) * (@stefacchio) * [1 year, 11 months ago](https://wordpress.org/support/topic/set-global-max-width-by-code-for-custom-theme/#post-17847536) * what? * I Just need something like a GB filter to set the global max width by code…. * Plugin Support [ying](https://wordpress.org/support/users/yingscarlett/) * (@yingscarlett) * [1 year, 11 months ago](https://wordpress.org/support/topic/set-global-max-width-by-code-for-custom-theme/#post-17847538) * You can set the global max width in GB’s setting, that doesn’t work? * Thread Starter [Stefano](https://wordpress.org/support/users/stefacchio/) * (@stefacchio) * [1 year, 11 months ago](https://wordpress.org/support/topic/set-global-max-width-by-code-for-custom-theme/#post-17847541) * Maybe I didn’t explain myself well, sorry but I’m not English.

Or maybe you can read It from theme.json? * Plugin Support [Alvind](https://wordpress.org/support/users/alvindcaesar/) * (@alvindcaesar) * [1 year, 11 months ago](https://wordpress.org/support/topic/set-global-max-width-by-code-for-custom-theme/#post-17847668) * Hi there, * If you defined the max-width value inside the settings array in `theme.json`, you can try using the `wp_get_global_settings` function to retrieve the value. * Or, why not just use the `generateblocks_global_container_width` filter hook and return the max-width value you set? That is simpler in my opinion. * Thread Starter [Stefano](https://wordpress.org/support/users/stefacchio/) * (@stefacchio) * [1 year, 11 months ago](https://wordpress.org/support/topic/set-global-max-width-by-code-for-custom-theme/#post-17850251) * I can’t find `generateblocks_global_container_width`, hoe use It? * however I want to set global width automatically Reading a value from my theme option * Plugin Support [ying](https://wordpress.org/support/users/yingscarlett/) * (@yingscarlett) * [1 year, 11 months ago](https://wordpress.org/support/topic/set-global-max-width-by-code-for-custom-theme/#post-17850313) * The link I provided should take you right to the line 1193 of the GB file, and the filter `generateblocks_global_container_width` should be on that line. * You can do something like this: * ```wp-block-code add_filter('generateblocks_global_container_width', function() { return 1500;}); ``` * Or you can add your own function which fetch your theme’s max-width to the filter. * Thread Starter [Stefano](https://wordpress.org/support/users/stefacchio/) * (@stefacchio) * [1 year, 11 months ago](https://wordpress.org/support/topic/set-global-max-width-by-code-for-custom-theme/#post-17851829) * It works! the only small problem is that the set value is visible in the blocks but in the settings is not read and whatever value is then entered on the settings page is not read. Is there no way to enter the value in the db or in the settings page?
