This presentation focuses on three main components of website design: concept, contrast, and color. Several examples are provided to illustrate effective concepts, including a dark background with changing images, a single scrolling page design, and a centered heading with a live background picture. Color contrast is also emphasized, as unbalanced colors can ruin a website's appearance. Different tones are shown to influence how professional or attractive a website feels to users, such as exciting, professional, or relaxing styles. In summary, the key aspects of concept, color, and tone that make a website look polished are demonstrated through various inspirational examples.
