I have noticed a common design element on several websites, but I am clueless about how it is achieved. Specifically, I am curious about the technique used to create the diagonal lines in the background of this screenshot from the digitalocean website: here. While I understand how to apply gradients or solid colors as backgrounds for div elements, I'm intrigued by more intricate designs like this one.
Additionally, I encountered another interesting feature where there are two sections separated with a unique curvature instead of a straight line. This raised questions about the coding techniques involved in achieving such visual effects, prompting me to seek further information online. I appreciate any insights you can provide on these topics. Thank you!
