The CSS `border-image` property is one of those properties you undoubtedly know exists but may not have ever reached for. In this article, Temani Afif demonstrates different approaches for using `border-image` to create clever decorative accents and shapes.

CSS gradients are represented by the gradient data type, a special type of image made of a progressive transition between two or more colors. You can choose between three types of gradients: linear (created with the linear-gradient() function), radial (created with radial-gradient()), and conic (created with the conic-gradient() function). You can also create repeating gradients with the repeating-linear-gradient(), repeating-radial-gradient(), and repeating-conic-gradient() functions.
