bad87fee1348bd9aed908826	Change the CSS of an Element Using jQuery	link https://cdnjs.cloudflare.com/ajax/libs/animate.css/3.2.0/animate.css	6		使用jQuery更改元素的CSS

Description

我们也可以使用jQuery直接更改HTML元素的CSS。 jQuery有一个名为.css()的函数，允许您更改元素的CSS。以下是我们将其颜色更改为蓝色的方法： $("#target1").css("color", "blue");这与普通的CSS声明略有不同，因为CSS属性及其值在引号中，并用逗号而不是冒号分隔。删除jQuery选择器，留下一个空的document ready function 。选择target1并将其颜色更改为红色。

Instructions

Tests

tests:
  - text: 您的<code>target1</code>元素应该有红色文本。
    testString: 'assert($("#target1").css("color") === "rgb(255, 0, 0)", "Your <code>target1</code> element should have red text.");'
  - text: 只使用jQuery将这些类添加到元素中。
    testString: 'assert(!code.match(/class.*animated/g), "Only use jQuery to add these classes to the element.");'
