我想重现一种网站风格,我想像他们一样为背景做,也就是说交替设计:印刷电路板,深灰色背景,印刷电路板,深灰色字体,但是我不知道我的情况该怎么做,有人可以帮助我吗?

站点:https://hydra.bot/ (screen of what I want to reproduce : https://prnt.sc/13kmrkc) 我在下面附上我的代码:

我想创建一个包含我的背景的 div,以便在我的 css 中定义一个精确的风格,但我从来没有这样做过,所以我真的不知道该怎么做(如何以正确的方式做到这一点)。由于我的 body class,目前我正在尝试 css,但它并不出名。如果有人有想法我很感兴趣。当然,我希望它最多是响应式的,因为自从我的网站创建之初我就尽量尊重响应式

你最初使用DIV的想法确实是正确的。

HTML

<div class="circuit"> Some content for the first part of the page</div>
<div class="dark"> Some content for the second part of the page</div>
<div class="circuit"> Some content for the third part of the page</div>

CSS

.circuit {
    background-image:url(URL_OF_THE_IMAGE);
}
.dark {
    background-color:#HEXCODE;
}
