离子4:更改离子含量背景不起作用 [英] ionic 4: changing ion-content background does not work

问题描述

我曾在global.scss中尝试过

i have tried in global.scss as

ion-content{
    background-image: url('assets/images/cover.jpg');
    -webkit-background-image: url('assets/images/cover.jpg');
    background-repeat: no-repeat;
    background-size:cover;
  }

但这不会渲染图像.尝试将路径也设置为./assets/images/cover.jpg.

but this does not render the image. tried path as ./assets/images/cover.jpg as well.

如果我在显示排除无效图像可能性的页面上放置了与img标签相同的图像.

if i put the same image as img tag on the page that shows up ruling out invalid image possibility.

我还尝试将homeage.scss放入

I also tried to put in the homeage.scss as

.myview {
    background-image: url('../../assets/images/cover.jpg');
    background-repeat: no-repeat;
    background-size:cover;
}

并在home.html中使用class ="myview"祝你好运

and using class="myview" in home.html no luck

推荐答案

您可以使用CSS-Variable --background更改离子含量的背景.

You can use the CSS-Variable --background to change the background of ion-content.

示例:

ion-content{
    --background: #fff url('../../assets/images/cover.jpg') no-repeat center center / cover;
}

将其放入您的组件，页面或全局scss.

Put this into your components, pages or global scss.
