The first principle is based on something that's the basis of web design – innovation. A designer must always keep the fact that innovation can make all the difference in a good web design in mind.
When you a have a website that makes it easy to find what the visitor is looking for and a careful UI and display of information, it can make a website useful.
The aesthetic quality of a website is the balance between the visual details and the usefulness of it. Beautiful websites are those that deliver a unique experience when you visit them, and present relevant content.
Easy to use
To make a website easy to understand, you have to have a clear view of the goals that the website has in order to design for those goals. You must keep the ease of use and how easy it is for a visitor to reach their goal in mind.
Always be aware of the goal of your ideas, create systems that are transparent and easy to use, concentrate on the essential features of a website when designing it and keep it simple and clean to be better understood by the user.
There will always be a new trend in web design. Just don't follow them without thinking carefully about the purpose of a radical change in your design.
