Description

CSS 边框具有style，color和width属性。假如我们想要创建一个 5px 的红色实线边框包围一个 HTML 元素，我们可以这样做：

<style>
  .thin-red-border {
    border-color: red;
    border-width: 5px;
    border-style: solid;
  }
</style>

Instructions

创建一个thick-green-border CSS class，该 class 应在 HTML 元素周围添加一个 10px 的绿色实线边框，将它应用在猫咪照片上。记得在一个元素上可以同时应用多个class，通过使用空格来分隔。例子如下： <img class="class1 class2">

Tests

tests:
  - text: '<code>img</code>元素应该含有<code>smaller-image</code> class。'
    testString: assert($("img").hasClass("smaller-image"));
  - text: '<code>img</code>元素应该含有<code>thick-green-border</code> class。'
    testString: assert($("img").hasClass("thick-green-border"));
  - text: '设置图片边框为<code>10px</code>。'
    testString: assert($("img").hasClass("thick-green-border") && parseInt($("img").css("border-top-width"), 10) >= 8 && parseInt($("img").css("border-top-width"), 10) <= 12);
  - text: '设置图片边框为<code>solid</code>实线。'
    testString: assert($("img").css("border-right-style") === "solid");
  - text: '<code>img</code>元素的边框颜色应该为绿色。'
    testString: assert($("img").css("border-left-color") === "rgb(0, 128, 0)");
