Repetition

A gaggle of geese, a school of fish, a pride of lions. Any time you bring a set of like items together, they form a group. In the same way, repetition of colors, shapes, textures, or similar objects helps to tie a web page design together so that it feels like a cohesive unit. The example in Figure 1.17 illustrates repetition. Even though there are other similar strokes around, the nine red strokes on the left-hand side appear to be a unified group because they repeat a shape, color, and texture. The strokes to the right of this group have no repeated pattern, so they appear isolated even though there are other shapes nearby.

Whether you notice it or not, repetition is often used in web site designs to unify elements of the layout. A good example of this concept at work among unmodified HTML elements is the bulleted list. The bullet that precedes each list item is a visual indicator that the bullet items are parts of a whole. Repeated patterns and textures can also help to unify a design. Take a look at the screenshot of Left Justified, the personal site of Australian designer Andrew Krespanis. This layout contains many eye-catching elements, but the repeated use of the red wood texture in the header, menu, and page borders literally hold this design together.

Proximity

Proximity is an obvious, but often overlooked way to make a group of objects feels like a single unit. Placing objects close together within a layout creates a focal point toward which the eye will gravitate. Take a look at the digital painting in Figure 1.15. While composed of a seemingly random assortment of strokes, the five strokes that are the closest together appear to form a unified object.

We practice the concept of proximity on the Web when we start setting margins and padding for elements. For instance, when I define the CSS style rules for most sites, I usually change the default margin that exists between common HTML elements such h1, h2, h3 …), paragraphs, block quotes, and even images. By altering these as headings (values, I can cause more or less space to appear between elements, thereby creating groups.

If you look at the two columns of text in Figure 1.16, you’ll notice that they look very similar. The only difference is in the placement of the headings. In the column on the left, the word “Unkgnome” is equip-distant from the top and bottom paragraphs. This results in a heading that looks more like a separator than a heading for the next paragraph. In the second column, the “Gnomenclature” heading is placed closer to the paragraph that follows it. In accordance with the rules of proximity, this heading appears to belong to that block of text.
