## Descrição
2018-10-10 18:03:03 -04:00
< section id = "description" > As bordas CSS têm propriedades como < code > style< / code > , < code > color< / code > e < code > width< / code > Por exemplo, se quisermos criar uma borda vermelha de 5 pixels em torno de um elemento HTML, poderíamos usar essa classe: < blockquote > < style> < br > .thin-red-border { < br > border-color: vermelho; < br > largura da borda: 5 px; < br > estilo de borda: sólido; < br > } < br > < / style> < / blockquote > < / section >

## Instruções
2018-10-10 18:03:03 -04:00
< section id = "instructions" > Crie uma classe chamada < code > thick-green-border< / code > . Essa classe deve adicionar uma borda verde sólida de 10 pixels em torno de um elemento HTML. Aplique a turma à sua foto de gato. Lembre-se de que você pode aplicar várias classes a um elemento usando seu atributo de < code > class< / code > , separando cada nome de classe com um espaço. Por exemplo: < code > < img class=" class1 class2" > < / code > < / section >

tests:
- text: Seu elemento < code > img</ code > deve ter a classe < code > smaller-image</ code > .

- text: Seu elemento < code > img</ code > deve ter a classe < code > thick-green-border</ code > .
testString: 'assert($("img").hasClass("thick-green-border"), "Your < code > img< / code > element should have the class < code > thick-green-border< / code > .");'
- text: Dê à sua imagem uma largura de borda de < code > 10px</ code > .
testString: 'assert($("img").hasClass("thick-green-border") & & parseInt($("img").css("border-top-width"), 10) >= 8 & & parseInt($("img").css("border-top-width"), 10) < = 12, "Give your image a border width of < code > 10px< / code > .");'
- text: Dê à sua imagem um estilo de borda < code > solid</ code > .
testString: 'assert($("img").css("border-right-style") === "solid", "Give your image a border style of < code > solid< / code > .");'
- text: A borda em volta do seu elemento < code > img</ code > deve ser verde.
testString: 'assert($("img").css("border-left-color") === "rgb(0, 128, 0)", "The border around your < code > img< / code > element should be green.");'
