我想在我的网站的页面上应用不同的背景。如何在页面上应用背景?

下面的代码适用于硬后台的所有产品页:

body.path-product { 
    background-image: url("/themes/contrib/bootstrap_subtheme_front_office/images/background-page.svg"); 
    -webkit-background-size: cover; 
    -moz-background-size: cover; 
    -o-background-size: cover; 
    background-size: cover; 
    background-repeat: no-repeat; 
    background-position: center center; 
    background-attachment: fixed; 
} 

我要应用于产品不同的背景/添加/ produit路径。这个怎么做 ?

在我的主题我创建了一个文件 “的HTML - 产品 - add.html.twig” 我在 “html.html.twig” 的内容粘贴。

{# 
/**

* Drupal page.

* - $head_title: A modified version of the page title, for use in the TITLE

如何把类“body.path-product-add”放在这个文件中?

是指所有产品或每个产品的动态? – Kai

@Kai背景已经应用于所有带有上述代码的产品。但我想在产品创建页面上应用不同的背景。路径在屏幕截图上。 – ZenImagine

如果您使用的是相同的类名,预计会发生,请创建另一个类,如body.path-product-create {background-image:...}并将此类添加到产品创建页面 – Mindless

你好@ZenImagine,

You can use another class for your body that corresponds that page. 

如果我是你的一部分,我将使用jQuery使特定页面的身体背景不同。见下面的代码。这个对我有用。

JQUERY

$(window).load(function(){ 
var x = window.location.href; 
    if(x == "full path link of the specific page"){ 
     $('body').addClass('productback'); 
    } 
}); 

CSS

body.productback{ 
background-image: url("your background image") !important; 
}

'@ ZenImagine':我不熟悉Drupal代码。但是,你可以参考这个链接来帮助你:https://www.drupal.org/node/2634364 – bellabelle

如果您只需要更换一个静态的网站上的背景图片,你可以简单地做一小块的jQuery:

jQuery

$('.path-product').css('background-image', 'url("https://www.w3schools.com/css/img_fjords.jpg")'); 

但是,如果你在一个动态网站工作,我肯定会投票无意识的答案。

对不起@ZenImagine,我不能说。我想这可能是一种从数据库中动态获取背景图像的方式,但我在Drupal中没有任何经验。 – Tedds
