Description
width
的属性,用于控制元素的宽度。就像字体一样,我们将使用px
(像素)来指定图像的宽度。例如,如果我们想要创建一个名为larger-image
的CSS类,它给HTML元素的宽度为500像素,我们将使用: <风格>
.larger-image {
宽度:500px;
}
</样式>
Instructions
smaller-image
的类,并使用它来调整图像大小,使其只有100像素宽。 注意 由于浏览器实现的差异,您可能需要100%缩放才能通过此挑战的测试。
Tests
tests:
- text: 您的<code>img</code>元素应该具有<code>smaller-image</code>类。
testString: 'assert($("img[src="https://bit.ly/fcc-relaxing-cat"]").attr("class") === "smaller-image", "Your <code>img</code> element should have the class <code>smaller-image</code>.");'
- text: 您的图片应为100像素宽。浏览器缩放应为100%。
