Design Patterns 4 Summary: Follow these 12 design guidelines for tab controls to distinguish tabs from site navigation and address click uncertainty.

Simplest GUI widgets are the building blocks for most functionality on the web, but it's rare to find sites that use all the dialog controls correctly. Even something as simple as radio buttons and checkboxes are incorrectly used half the time.

And let's not even get started on drop-down menuswhich are horribly abused. This article talks about another design element that gets frequently misused: Here, I'm talking about in-page tabs, as shown in the several example screenshots below.

These are the tabs you might design yourself, as part of your website or web-based application. A different kind of tabs is used as browser chrome to allow users to keep multiple pages open in the browser at the same time. I'm not discussing browser tabs in this article.

Tab-Usability Guidelines Here are 12 design guidelines for using tabs: Use tabs to alternate between views within the same context, not to navigate to different areas. This is the single most important point, because staying in place while alternating views is the reason we have tabs in the first place.

Logically chunk the content behind the tabs so users can easily predict what they'll find when they select a given tab.

If you don't find clearly distinct groupings, then tabs are likely the wrong interface control for managing your content.

Use tabs only when users don't need to see content from multiple tabs simultaneously.

If people do need to compare the info behind different tabs, then having to switch back and forth puts an added burden on their short-term memoryincreases cognitive load and interaction costand lowers usability compared to a design that puts everything on one big page.

Design tabs that are parallel in nature. If the tabs are significantly dissimilar, users will interpret them as site navigation.

Make sure that the highlighting is prominent enough so people can tell which tab is selected. With only 2 tabs, it is hard to tell which one is selected. In addition to highlighting, you can mark the current tab by size, a boldfaced label, an icon, or by making it appear to be in front of the other tabs.

As shown in the above example, such additional signaling is important if there are only two tabs. The unselected tabs should be clearly visible and readable, reminding the user of the additional options.

If the nonhighlighted tabs are faded too much into the background, there's a risk that users will never click them and never discover the many hidden features.

Connect the current tab to the content area, just as if you were shuffling several physical index cards with tabs stuck to them.Write an essay in which you explain how Paul Bogard builds an argument to persuade his audience that natural darkness should be preserved.

In your essay, analyze how Bogard uses one or more of the features in the directions that precede the passage (or features of your own choice) to strengthen the logic and persuasiveness of his argument.
