   ДОТОШНО. Студия продуманных решений
   Основные стили сайта.

   Как устроен файл:
   1. Цвета, шрифты и размеры (переменные). Поменяли здесь, поменялось везде.
   2. Базовые правила для текста.
   3. Шапка и меню.
   4. Общие блоки: кнопки, секции, иллюстрации.
   5. Главная страница.
   6. Страницы проектов.
   7. Страница «О студии».
   8. Подвал, галерея, увеличение картинок.
   9. Адаптация под телефоны и планшеты.
