Human mind to receive the new knowledge, skill, or attitude through a website follow the psychological principles and rules. These rules have been already studies as learning process.
Learning theories explain how human receive, process, and retain new knowledge, skill and attitude.
Some of learning theories are mentioned here.
Gestalt theory was first developed in the early 1900s by Austrian and German psychologists. Some of the notable founders of Gestalt theory include Max Wertheimer, Wolfgang Kohler, and Kurt Koffka. The word 'Gestalt' means whole or 'form in German. One of the main beliefs of Gestalt theory is that something is a whole of interacting parts that can be separated, analyzed, and rearranged in the whole. In other words, the whole is different from the sum of its parts.
the tendency of the visual system to simplify a scene into the main object that we are looking at (the figure) and everything else that forms the background (or ground).

When looking at a visual scene, people tend to look for ways to differentiate between the figure and the ground.
We use these as the techniques in web designing for directing the use's mind on the subject that we want
When creating visual images for display, ensure it is easy for viewers to distinguish the figure where you want them to pay attention. Make the figure clear and distinct, standing out from the background.
Objects in the foreground tend to be crisp and distinct while those in the background are blurry or hazy.
Since the early days of graphical user interfaces, screens have employed shadows to help users understand how to use an interface. Images and elements with shadows seem to pop off of a page, and it gives users the impression that they can physically interact with the element. Even though visual cues vary from app to app, users can usually rely on two assumptions:
Elements that appear raised look like they could be pressed down (clicked with the mouse or tapped with a finger). This technique is often used as a visual signifier for buttons.
Elements that appear sunken look like they could be filled. This technique is often used as a visual signifier for input fields.
Contrast: The high contrast between objects can lead to the perception of figure and ground. The Rubin vase is one example.
There are some great tips to consider when using Color to add Contrast to your artwork!
some more pointers to consider when working with Shapes!
Size: Images that appear to be larger will be perceived as closer and part of the figure while those that are smaller will seem further away and part of the background.
Size is simply how small or big an element is in relation to other objects within a design. Generally, we use size to make a particular element stand out or to give it importance. However, size becomes a much more powerful design tool when it is considered alongside scale.
An object isolated from everything else in a visual scene is more likely to be seen as a figure versus background.
“white space” refers to the space that surrounds the elements. You may find the term “negative space” here and there, indicating the exact same thing.
White space is used to:

It explains how we perceive incomplete shapes (Palmer & Rock, 1994). When there is missing information in an image, the eye ignores the missing information and fills in the gaps with lines, color or patterns from the surrounding area to complete the image.
