Google сетка галереи
Этот Blueprint является адаптивной сеткой галереи основанной на галереи Google для руководства Chromebook Getting Started. В этом Blueprint мы используем Masonry для сетки и 3D-преобразования для навигации детальной информации. Для небольших экранов у нас есть некоторые примеры media queries запросов, которые регулируют расположение сетки, а также вид галереи.
Осуществлять навигацию в галереи можно также клавишами «влево», «вправо» на вашей клавиатуре, а закрыть просмотр можно клавишей «Esc».
Пожалуйста, обратите внимание, что мы используем CSS 3D-преобразования, которые поддерживаются только в современных браузерах.
Изображения, используемые в демо созданны с использованием граффити форм от Луки Робертс.
