Sass: Utilizing Random Background Images from a Designated List

SASS, a powerful CSS extension, provides advanced functionality for stylizing web pages. One such feature is the ability to dynamically select background images from a predetermined list. This article explores how to achieve this using SASS.

Question:

How can I use SASS to generate CSS code that randomly selects a background image from a provided list of URLs?

Answer:

To accomplish this task, harness the power of SASS's random() function, introduced in version 3.3.0. This function generates a random number within a specified range. By combining this functionality with a pre-defined list of image URLs, you can create dynamic background image assignments.

Consider the following SASS code snippet:

$imgKey: random(5);

$list: "image1.jpg", "image2.jpg", "image3.jpg", "image4.jpg", "image5.jpg";
$nth: nth($list, $imgKey);

#footer-widgets .container .row {
    background-image: url("http://domain.com/blablabla/#{$nth}");
    background-position: right bottom;
    background-repeat: no-repeat;
}

In this example, the $list variable holds the list of image URLs. The $imgKey variable generates a random number between 1 and 5, representing the index of the image to be selected from the list. The nth($list, $imgKey) function extracts the image URL at that index.

Additional Notes:

• The randomly selected background image will only change when the SASS is compiled. This may not happen every time a page is visited.
• You can adjust the range of the random() function to match the number of images in your list.
• Explore the SASS documentation for more information on the random() and nth() functions.
