Hi @Alejandro Mery. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To address your question about loading CSS variables using a reactive URL in useHead() styles and making it client-only, we can use a combination of useHead() and the <ClientOnly> component in Nuxt 3. Here's how you can approach this: 1. First, we'll use useHead() to set up the reactive CSS variables: 
<script setup>
import { ref, computed } from 'vue'

const imageUrl = ref('<https://example.com/image.jpg'>)

const styles = computed(() => [
  {
    innerHTML: `:root { --bg-image: url(${imageUrl.value}); }`
  }
])

useHead({
  style: styles
})
</script>
<script setup>
import { ref, computed } from 'vue'

const imageUrl = ref('<https://example.com/image.jpg'>)

const styles = computed(() => [
  {
    innerHTML: `:root { --bg-image: url(${imageUrl.value}); }`
  }
])

useHead({
  style: styles
})
</script>
2. To make this client-only, we can wrap the component that uses these styles in a <ClientOnly> component: 
<template>
  <ClientOnly>
    <div class="my-component">
      <!-- Your component content here -->
    </div>
  </ClientOnly>
</template>

<style scoped>
.my-component {
  background-image: var(--bg-image);
}
</style>
<template>
  <ClientOnly>
    <div class="my-component">
      <!-- Your component content here -->
    </div>
  </ClientOnly>
</template>

<style scoped>
.my-component {
  background-image: var(--bg-image);
}
</style>
By using <ClientOnly>, the styles will only be applied on the client-side, preventing any server-side rendering issues. For more information on using <ClientOnly>, you can refer to the Nuxt 3 documentation on Client Components (https://nuxt.com/docs/guide/directory-structure/components#client-components). Remember that when using client-only components, you might need to handle any potential layout shifts or loading states appropriately.
