localeTitle: Уменьшить непрозрачность элемента
---
## Description
<section id='description'>
Свойство <code>opacity</code> в CSS используется для настройки непрозрачности или, наоборот, прозрачности для элемента. <blockquote> Значение 1 непрозрачно, что совсем не прозрачно. <br> Значение 0,5 равно половине видимости. <br> Значение 0 полностью прозрачно. </blockquote> Приведенное значение будет применяться ко всему элементу, будь то изображение с некоторой прозрачностью или цвета переднего плана и фона для блока текста.
</section>
## Instructions
<section id='instructions'>
Установите <code>opacity</code> тегов привязки на 0.7, используя класс <code>links</code> чтобы выбрать их.
</section>
## Tests
