Основы использования

Управление непрозрачностью фильтров фона

Используйте утилиты backdrop-opacity-{amount} для управления непрозрачностью других фильтров фона, применяемых к элементу.

backdrop-opacity-10

backdrop-opacity-60

backdrop-opacity-95

<div class="backdrop-opacity-10 backdrop-invert bg-white/30 ...">
  <!-- ... -->
</div>
<div class="backdrop-opacity-60 backdrop-invert bg-white/30 ...">
  <!-- ... -->
</div>
<div class="backdrop-opacity-95 backdrop-invert bg-white/30 ...">
  <!-- ... -->
</div>

Удаление фильтров фона

To remove all of the backdrop filters on an element at once, use the backdrop-filter-none utility:

<div class="backdrop-blur-md backdrop-opacity-60 md:backdrop-filter-none">
  <!-- ... -->
</div>

This can be useful when you want to remove backdrop filters conditionally, such as on hover or at a particular breakpoint.


Применяя условно

Tailwind lets you conditionally apply utility classes in different states using variant modifiers. For example, use hover:backdrop-opacity-60 to only apply the backdrop-opacity-60 utility on hover.

<div class="backdrop-opacity-100 hover:backdrop-opacity-60">
  <!-- ... -->
</div>

For a complete list of all available state modifiers, check out the Hover, Focus, & Other States documentation.

Контрольные точки и медиа-запросы

You can also use variant modifiers to target media queries like responsive breakpoints, dark mode, prefers-reduced-motion, and more. For example, use md:backdrop-opacity-60 to apply the backdrop-opacity-60 utility at only medium screen sizes and above.

<div class="backdrop-opacity-100 md:backdrop-opacity-60">
  <!-- ... -->
</div>

To learn more, check out the documentation on Responsive Design, Dark Mode and other media query modifiers.


Использование пользовательских значений

Настройка вашей темы

По умолчанию Tailwind включает в себя несколько утилит общего назначения backdrop-opacity. Вы можете настроить эти значения, отредактировав theme.backdropOpacity или theme.extend.backdropOpacity в вашем файле tailwind.config.js.

tailwind.config.js
module.exports = {
  theme: {
    extend: {
      backdropOpacity: {
        15: '.15',
      }
    }
  }
}

Дополнительные сведения о настройке темы по умолчанию смотрите в документации настройка темы.

Произвольные значения

If you need to use a one-off backdrop-opacity value that doesn’t make sense to include in your theme, use square brackets to generate a property on the fly using any arbitrary value.

<div class="backdrop-opacity-[.15]">
  <!-- ... -->
</div>

Learn more about arbitrary value support in the arbitrary values documentation.
