In your quest to set an image as a fullscreen background for your webpage, you've encountered an issue: the image doesn't fully cover the page and repeats on the rightmost end. Here's how you can resolve this using CSS techniques:
The background-size property can be used to control the size of the background image. In this case, using the value cover will ensure that the image covers the entire page, even if it means stretching or cropping the image to fit:
background-size: cover;
To ensure the image is centered both horizontally and vertically, you can use the background-position property with the value 50% 50%:
background-position: 50% 50%;
To prevent the background image from scrolling with the page content, you can set the background-attachment property to fixed. This will fix the image in place, allowing the page to scroll behind it:
background-attachment: fixed;
You can write a shorthand version of both solutions using the following syntax:
background: url(image.jpg) fixed 50% / cover;
where the / separates the background-position and background-size properties.
Note that Safari has a bug with the shorthand syntax described above. To use it in Safari, you should separate the properties as follows:
background-image: url(image.jpg); background-attachment: fixed; background-position: 50% 50%; background-size: cover;
By implementing these techniques, your background image will now fully cover the page and remain centered, providing a visually appealing and responsive background for your website.
