我正在使用Ionic 4 Angular应用程序并设置<ion-slide>
的样式以显示背景。
我在CSS中使用background-size: cover;
。在浏览器和iOS设备上,一切看起来都很完美,但是在Android设备上运行时,背景无法正确显示。我已经附上了一些屏幕截图,供参考。
HTML:
<ion-slide class="step-two">
<div class="slide-container">
<h1>Find</h1>
<p>Tap into stockists and discover where to buy your favourite beers.</p>
<ion-img class="swipe-img" src="../../assets/imgs/swipe.svg"></ion-img>
</div>
</ion-slide>
CSS:
.step-two {
background: linear-gradient(rgba(121, 168, 226, .9), rgba(0, 0, 0, .7)), url("../../assets/imgs/onboarding-bg2.jpg") no-repeat center;
background-size: cover;
color: var(--ion-color-primary-contrast);
}
.slide-container {
width: 80%;
}
在iOS设备上正确显示:
在Android设备上显示不正确:
我试图像这样设置幻灯片的高度:
.step-two {
background: linear-gradient(rgba(121, 168, 226, .9), rgba(0, 0, 0, .7)), url("../../assets/imgs/onboarding-bg2.jpg") no-repeat center;
background-size: cover;
color: var(--ion-color-primary-contrast);
height: 100%; // This didn't work. The height was less than the view height of the device (about 30% in fact). Also tried 100vh which filled the view height but didn't fix the cover issue.
}
除了封面尺寸不正确外,似乎背景图片也未在Android上居中显示。
任何帮助,不胜感激。谢谢。

不要使用背景大小作为“封面”,而应使用“ 100%100%”。这将根据容器设置图像的100%宽度和100%高度。像这样:
background-size:100% 100%;
示例:
.step-two {
background: linear-gradient(rgba(121, 168, 226, .9), rgba(0, 0, 0, .7)), url("../../assets/imgs/onboarding-bg2.jpg") no-repeat center;
background-size: 100% 100%;
color: var(--ion-color-primary-contrast);
height: 100%;
}
