Hydration mismatch in Nuxt UI

Using 
<UInput/>
<UInput/>
And custom config 
input: {
            wrapper: "relative",
            base: "relative block w-full disabled:cursor-not-allowed disabled:opacity-75 focus:outline-none border-0",
            default: {
                size: "md",
                color: "gray",
                variant: "outline",
            },
            error: {

            },
            color: {
                white: {
                    outline:

                }
            },
        },

                }
            },
        },

Hi @Kyllian. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To address the hydration mismatch you're experiencing with Nuxt UI's UInput component, you need to ensure that your custom configuration is properly applied and that it overrides the default styles consistently on both the server and client side. Here are some steps to fix this issue: 1. Make sure you're applying your custom configuration correctly. In your app.config.ts file, you should structure your UI configuration like this: 
export default defineAppConfig({
  ui: {
    input: {
      // Your custom input configuration here
    }
  }
})
export default defineAppConfig({
  ui: {
    input: {
      // Your custom input configuration here
    }
  }
})
2. The hydration mismatch occurs because the server-side rendering is using the default Nuxt UI styles, while the client-side is attempting to use your custom styles. To fix this, you need to ensure that your custom styles are applied consistently. 3. Instead of completely overriding the default styles, try to extend them. This approach helps maintain consistency between server and client rendering. Here's an example of how you might modify your configuration: 
export default defineAppConfig({
  ui: {
    input: {
      default: {
        size: "md",
        color: "gray",
        variant: "outline",
      },
      color: {
        gray: {
          outline: "ring-1 ring-gray-300 focus:ring-1 focus:ring-main-500 py-2 px-3 leading-tight transition duration-150 ease-in-out"
        }
      }
    }
  }
})
export default defineAppConfig({
  ui: {
    input: {
      default: {
        size: "md",
        color: "gray",
        variant: "outline",
      },
      color: {
        gray: {
          outline: "ring-1 ring-gray-300 focus:ring-1 focus:ring-main-500 py-2 px-3 leading-tight transition duration-150 ease-in-out"
        }
      }
    }
  }
})
4. If you want to completely override the styles, you need to provide all the necessary classes to replace the default ones. This includes classes for different states (like focus, disabled) and color schemes (light and dark mode). 5. After making these changes, clear your Nuxt cache and rebuild your application to ensure the new styles are applied correctly. If you're still experiencing issues after trying these steps, it might be helpful to check the Nuxt UI documentation on theming for more detailed information on customizing components. Remember that when overriding styles, you need to be comprehensive to avoid inconsistencies between server and client rendering. If you're unsure about which classes to include, you can refer to the default configuration in the Nuxt UI Input component documentation. If the problem persists, you might want to consider using the ui prop on the UInput component for more specific overrides: 
<UInput :ui="{ base: 'your-custom-classes-here' }" />
<UInput :ui="{ base: 'your-custom-classes-here' }" />
This approach allows you to target specific instances of the component without affecting the global configuration. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
