How Can SASS Help You Randomly Select Background Images?

Random Background Image Selection in SASS

Looking to spruce up your web pages with an element of surprise? SASS makes it possible to randomly select a background image from a predefined list, adding a touch of dynamism to your website.

Generating Random Background Images with SASS

Sass offers a convenient random function that can be utilized to pick a random number within a specified range. By combining this function with a list of image URLs, we can create CSS with a background image that varies each time SASS is compiled.

Example Code:

$imgKey: random(5);

$list: apple, banana, cherry, durian, eggplant;
$nth: nth($list, $imgKey);

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

In this example, $imgKey retrieves a random number between 1 and 5. The $nth function then selects the image URL corresponding to that random number from the $list variable. The result is a CSS rule that assigns a random background image to the specified container row.

Compilation and Image Selection

It's important to note that the random background image will change only when the SASS is recompiled, not every time the page is visited. This ensures that the random selection is consistently reflected across multiple page loads, preventing abrupt visual shifts.
