Is there a way to adjust the opacity of all Vuetify input fields?

I designed a component that includes the following code:

<v-text-field
  style="opacity: 1 !important"
  class="foo"
  base-color="primary"
></v-text-field>

However, I discovered that the opacity was not changing as expected. Upon inspecting the element, I observed that it was rendered in the following structure:

<div class="v-input foo ..."> <!-- fallthrough attrs are applied here -->
  <div class="v-input__control">
    <div class="v-field ...">
      <div class="v-field__overlay">...</div>
      <div class="v-field__loader">...</div>
      <div class="v-field__field">...</div>
      <div class="v-field__outline ...">...</div>
    </div>
  </div>
</div>

The CSS for the v-field__outline class is defined as follows:

.v-field__outline {
  --v-field-border-opacity: 0.38;
  ...
}

I am looking to adjust this opacity value. Can anyone provide guidance on how to achieve this in an efficient manner?

Answer №1

Typically, Vuetify offers the flexibility to customize and modify components through its API. However, in this particular scenario, adjusting the border opacity of a v-text-field is not directly accessible through the API. The good news is that most CSS-related customizations can still be achieved with the right selection approach.

In order to target internal elements within a component, employing a deep selector becomes necessary.

<style scoped>
  .v-text-field :deep(.v-field__outline) {
    --v-field-border-opacity: 1;
  }
</style>

Check out this Vuetify Playground example for reference

If a style modification needs to be applied globally (non-scoped), skipping the deep selector is advisable.

<style>
  /* global style */
  .v-field__outline {
    --v-field-border-opacity: 1;
  }
</style>

Special thanks to @yoduh for the valuable insights that led me to discover a solution that resolved my issue. My primary objective was to eliminate the opacity effect without relying on CSS, but solely leveraging the capabilities of "Vuetify."

The culprit CSS rule responsible for the opacity is as follows:

.v-field--variant-filled .v-field__outline::before {
  ...
  opacity: var(--v-field-border-opacity);
}

To address this, I made adjustments in my settings.scss file:

@use 'vuetify/settings' with (
  $field-outline-opacity: 1
);

As a result, the opacity is now set to 1.
