The stitched glowing effect is generally used in the design of classical or retro-themed websites. You can also call it a Denim effect if you use blue color for the effect as it looks similar to the classic original denim. It is one of the best effect to understand the concept of radial-gradient and dashed property of border.
Approach: The approach is simple, we will use the dashed property for stitch effect and radial-gradient for the glow effect. The below code is the implementation of the above approach.
In the above example, we have a <h1> element and first we align it to center of the page and then apply radial-gradient property to give it a glow effect and border dashed property to give stitch effect. Border-radius is completely optional and use of it comes to personal preferences.
