Tilted Angles in Sass

This article explores creating tilted angles in CSS using Sass, offering a sophisticated solution that avoids the limitations of other methods. Instead of using base64 encoded images, skewed pseudo-elements, or the Angled Edges library, this approach leverages a clever gradient technique.

Traditional methods like base64 images hinder customization, while skewing is cumbersome, and the Angled Edges library requires fixed dimensions. This new method uses a half-transparent, half-solid linear gradient applied to an absolutely positioned pseudo-element. The gradient's angle dictates the tilt.

A Sass mixin encapsulates this, accepting the angle and color as parameters. The key challenge lies in dynamically calculating the pseudo-element's height based on the angle. This is solved using trigonometry and the Pythagorean theorem.

A Sass function, get-tilted-height(), performs this calculation. It uses the sine function and the Pythagorean theorem (b = √(c² - a²)) to determine the height (b) based on the angle (B) and a width of 100%.

The tilted() mixin then applies the calculated height (via padding-top) to the pseudo-element, along with the gradient and color styling. The container element receives the background color for consistency. The mixin uses position: relative on the container to establish the positioning context for the pseudo-element.

While this method is more complex than others, it offers greater flexibility and avoids the drawbacks of simpler approaches. The article concludes by suggesting potential improvements, such as handling existing ::before pseudo-elements and allowing bottom tilting. The author also notes that using JavaScript-based Sass functions (via Eyeglass or Sassport) could enhance the solution.
