--description--
和 width 屬性類似,你可以使用 CSS 裏面的 height 屬性來指定元素的高度。 下面這段代碼可以把圖片的高度設置爲 20px:
img {
  height: 20px;
}
--instructions--
給 h4 標籤添加 height 屬性並將屬性值設置爲 25px。
注意: 可能需要將瀏覽器的縮放比調整爲 100% 才能通過這一挑戰。
--hints--
h4 的 height 屬性值應爲 25px。
assert(
  Math.round(document.querySelector('h4').getBoundingClientRect().height) ===
    25 &&
    /h4{\S*height:25px(;\S*}|})/.test($('style').text().replace(/\s/g, ''))
);
