## Description
2018-10-16 13:43:02 +00:00
< section id = "description" > Além das classes, cada elemento HTML também pode ter um atributo < code > id< / code > . Há vários benefícios em usar os atributos < code > id< / code > : você pode usar um < code > id< / code > para estilizar um único elemento e, posteriormente, aprenderá que pode usá-los para selecionar e modificar elementos específicos com JavaScript. Atributos < code > id< / code > devem ser exclusivos. Os navegadores não reforçam isso, mas é uma prática recomendada amplamente aceita. Então, por favor, não dê a mais de um elemento o mesmo atributo < code > id< / code > . Veja um exemplo de como você atribui ao elemento < code > h2< / code > o id de < code > cat-photo-app< / code > : < code > < h2 id=" cat-photo-app" > < / code > < / section >
