58 bytes of css to look great nearly everywhere

58 bytes of CSS to look great nearly everywhere

When making this website, i wanted a simple, reasonable way to make it look good on most displays. Not counting any minimization techniques, the following 58 bytes worked well for me:

main {
  max-width: 38rem;
  padding: 2rem;
  margin: auto;
}

Задача:
Используя открытый API (https://dog.ceo/dog-api/) написать небольшое web-приложение на стэке React 16.3.x + Redux + React-Router.
Приложение должно иметь более чем один роут: список собак, страница конкретной собаки.
Сборка должна производиться с помощью webpack версии 4.x.x.
Покрытие тестами (хотя бы одного компонента) с помощью Jest
Обязательное и обоснованное использование EcmaScript 6+ фич (babel-present-env).
Код должен быть отформатирован по eslint airbnb (https://www.npmjs.com/package/eslint-config-airbnb)
Дизайн и структура файлов/папок проекта приложения остаётся на совесть выполняющего данное тестовое задание.

Pixi Performance Tips
Global :
- Only optimize when you need to! Pixi can handle a fair amount of content off the bat.
- Be mindful of the complexity of your scene. The more objects you add the slower things will end up.
- Order can help, for example sprite / graphic / sprite / graphic is slower than sprite / sprite / graphic / graphic
- Some older mobile devices run things a little slower. passing in the option 'legacy:true' to the renderer can help with performance
- Culling, is disabled by default as its often better to do this at an application level. If you are GPU it will improve performance, if you are CPU bound - it will degrade performance
Sprites:
- Use spritesheets where possible to minimize total textures
- Sprites can be batched with up to 16 different textures (dependent on hardware)
