1. Color: A well thought out color palette can go a long way to enhance the user experience. Vibrant colors create emotion and should be used delicately. White space/ negative space is very effective at giving your website a modern and uncluttered look.
2. Layout: Placing content randomly on your web page can end up with a sudden appearance that is messy. Grid-based layouts arrange content into sections, columns and boxes that line up and feel balanced, which leads to a better-looking website design.
