看了下代码,就是给 section 加了个 background,为了使固定宽度的图片填充各分辨率的屏幕,将其设置为 cover

HTML 部分:

1

2

<code><section class="billboard">...</section>

</code>

Copy after login

CSS 部分:

1

2

3

4

5

<code>.billboard {

    background: url('../img/mirai.jpg') center center repeat-x;

    background-size: cover;

}

</code>

Copy after login
Copy after login

我对该网站所用的建站流程不是很了解。但是找出图片的来源还是很简单的。

首先,加载了一张图片的前提是该图片被请求。所以查看请求的图片,第一个就是该图片,名字是mirai.jpg.

然后,将该图片导入页面的代码可能出现在三处,html中,js中和css中,html和js经过搜索都搜不到mirai。那么对所有的css进行排查,发现costoms.css中包含这么一段:

1

2

3

4

5

<code>.billboard {

    background: url('../img/mirai.jpg') center center repeat-x;

    background-size: cover;

}

</code>

Copy after login
Copy after login

于是在控制台中执行$('.billboard')选择到一个对象,及网站标题所在的section。换句话说,只要通过css将网站标题的背景图设成该图片即可。
顺便一提,该图片是远大于网页标题的,所以作者通过对标题设置了很大的padding来保证图片可以完全显示而不被裁剪或压缩。
