Пробую на каких-то простых примерах — всё ясно. Чуть-чуть усложняю код — и всё разлетается. Стала смотреть документацию и разные статьи, нашла хорошее объяснение и рекомендации и захотелось поделиться. Сначала написала в обсуждениях к уроку, но там только Никита прочитал :-)**\n\n::programs\n\nУ директивы @extend совершенно неочевидный механизм компиляции и, если не обратить на это внимание, можно неожиданно для себя получить в CSS много кода непонятного происхождения. Или же ошибки при компиляции, которые остановят всю работу. \n\n**[Вот пример из статьи \"What Nobody Told You About Sass's @extend\"](https://www.sitepoint.com/sass-extend-nobody-told-you/)**. Догадайтесь, какой код будет здесь на выходе?\n\n```css\n.message + .message {\n margin-bottom: .5em;\n}\n\n.message-error {\n @extend .message;\n}\n```\n\nПодсказка, вернее ответ для «не гениев» (думаю, окажусь в хорошей большой компании :-) \n\n```css\n.message + .message, \n.message-error + .message-error, \n.message + .message-error, \n.message-error + .message { \n margin-bottom: .5em;\n}\n```\n\n**[Вот тут более понятное объяснение и совет, как писать код при использовании @extend:](https://csswizardry.com/2014/01/extending-silent-classes-in-sass/)** \n\nАвтор предупреждает, что его решение тоже не идеально, да и статья довольно старая (2014 года), но объяснения и примеры здесь показались мне более лёгкими для понимания, чем в документации. \n\nОчень примитивно говоря: Использовать @extend только с шаблонными селекторами.\n\nТо есть вместо:\n\n```css\n.info {color: blue;}\n```\n\nПишем \n\n```css\n.info, %info {color: blue;}\n```\n\nИ вместо \n\n```css\n.modal-info {\n //more code …\n @extend .info;\n}\n```\n\nПишем \n```css\n.modal-info {\n //more code …\n @extend %info;\n}\n```\nВот, кстати, ссылка на документацию ([на русском](https://sass-scss.ru/documentation/pravila_i_direktivi/direktiva_extend/) и [на английском](https://sass-lang.com/documentation/at-rules/extend)).\n\n::posts\n\nДля себя делаю вывод: @extend с использованием классов – это для самых смелых и сообразительных. А я уж лучше поосторожничаю. Всё-таки все эти надстройки предназначены для ускорения работы, а не для ввода в мысленный ступор и потери времени и веры в собственные умственные способности. \n\nНу и совсем тихонько в сторону: Не употребляйте @extend вместе с классами. Не смешивайте.

<p>Для себя делаю вывод: @extend с использованием классов – это для самых смелых и сообразительных. А я уж лучше поосторожничаю. Всё-таки все эти надстройки предназначены для ускорения работы, а не для ввода в мысленный ступор и потери времени и веры в собственные умственные способности.</p>
<p>Ну и совсем тихонько в сторону: Не употребляйте @extend вместе с классами. Не смешивайте. Наутро голова болеть будет ;-)</p></div><div class=""><div
