Obrázky jsou ve všech velikostech. Stejně tak obrazovky. Automaticky responzivní obrázky upravit tak, aby odpovídala velikosti obrazovky.
Vytvářejte responzivní obrázky přidáním třídy .img-fluid
na značku <img>
. Obrázek se pak pěkně změní na nadřazený prvek.
Třída .img-fluid
platí max-width: 100 %;
a výška: auto;
k obrázku:
<img class="img-fluid" src="ny.jpg" alt="New York">
