A website is more like an art. You could stoke a few lines with different colors on a canvas and call it a drawing but that is far away from what people admire and call it as an art.
A website should not just be colorful and attractive, but should serve the purpose of converting. It should be easy to navigate and tell the visitor everything they're looking for, as quickly as possible, without frustrating them.
Content is another important part of the website design. People need emailrmation and that's exactly why they're visiting your website. Either you sell products or provide a service, you need to educate them clearly.
