Imagens responsivas

As imagens vêm em todos os tamanhos. O mesmo acontece com as telas. Imagens responsivas automaticamente ajuste para caber no tamanho da tela.

Crie imagens responsivas adicionando uma classe .img-fluid para a tag <img>. A imagem será então dimensionada perfeitamente para o elemento pai.

A classe .img-fluid aplica max-width: 100%; e height: auto; para a imagem:

Exemplo

<img class="img-fluid" src="ny.jpg" alt="New York">
