--description--
和 width
属性类似,你可以使用 CSS 里面的 height
属性来指定元素的高度。下面这段代码可以把图片的高度设置为 20px:
img {
height: 20px;
}
--instructions--
给 h4
标签添加 height
属性并将属性值设置为 25px。
**注意:**可能需要将浏览器的缩放比调整为 100% 才能通过这一挑战。
--hints--
h4
的 height
属性值应为 25px
。
assert(
Math.round(document.querySelector('h4').getBoundingClientRect().height) ===
25 &&
/h4{\S*height:25px(;\S*}|})/.test($('style').text().replace(/\s/g, ''))
);
