Currently, I have a webpage that utilizes a background image set up like this:
body {
background-image : url("https://example.com/image.png");
background-size : cover;
background-repeat : no-repeat;
}
While this setup works well for screens with a 16:9 aspect ratio, on mobile phones with a 9:16 aspect ratio, the image only covers about half of the screen!
Is there a way to specify different images based on the aspect ratio of the screen?
If you're experiencing issues with your image position, you can attempt the following solution:
body{
background: url(http://www.planwallpaper.com/static/images/nature-wallpapers-hd.jpg) no-repeat top center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}For further clarification on the background-size property, you may find this resource helpful:
CSS background image to fit width, height should auto-scale in proportion
It is inevitable when using background-size: cover that the browser will attempt to fill the element with the same background. Although adjustments can be made with background-position, it may not be very effective in this situation.
An alternative approach would be to utilize media queries to display different backgrounds based on screen size.
For example:
@media only screen and (max-width: 640px) {
background: url(../images/mobile-background.jpg) no-repeat center center;
background-size: cover;
}
@media only screen and (min-width: 641px) {
background: url(../images/large-background.jpg) no-repeat center center;
background-size: cover;
}
By implementing this method, specific images can be selected for each scenario, providing advantages such as optimized image size for quicker loading times and reduced bandwidth consumption for the user. This approach can also result in improved Page Speed performance.
