In the last 5-6 months, we started seeing a lot of web designs that employ visible grid lines, as well as horizontal, vertical, and diagonal lines. These lines allow to separate websites into logical blocks and create a visual path guiding visitors from one point to another. Also, thin lines can add a delicate vibe to the website, while bold ones contribute to a more brutal geometric style. However, this technique should be used with caution, as overuse of lines can make websites look somewhat heavy.
