 <p>For section-related screens, offering touchable and keyboard-focusable targets in the parent is generally the most straightforward and familiar kind of touch-based navigation interface. Examples of such targets include buttons, fixed-size list views, or text links, although the latter is not an ideal UI (user interface) element for touch-based navigation. Upon selecting one of these targets, the child screen is opened, replacing the current context (screen) entirely. Buttons and other simple targets are rarely used for representing items in a collection.</p>

-<p>Several best practices apply when using tabs. Tabs should be persistent across immediate related screens. Only the designated content region should change when selecting a tab, and tab indicators should remain available at all times. Additionally, tab switches should not be treated as history. For example, if a user switches from a tab <em>A</em> to another tab <em>B</em>, pressing the BACK button (more on that in the <a href="ancestral-temporal.html">next lesson</a>) should not re-select tab <em>A</em>. Tabs are usually laid out horizontally, although other presentations of tab navigation such as using a drop-down list in the <a href="{@docRoot}guide/topics/ui/actionbar.html">Action Bar</a> are sometimes appropriate. Lastly, and most importantly, <em>tabs should always run along the top of the screen</em>, and should not be aligned to the bottom of the screen.</p>

 <p>A common criticism is that space must be reserved for the tab indicators, detracting from the space available to tab contents. This consequence is usually acceptable, and the tradeoff commonly weighs in favor of using this pattern. You should also feel free to customize tab indicators, showing text and/or icons to make optimal use of vertical space. When adjusting indicator heights however, ensure that tab indicators are large enough for a human finger to touch without error.</p>

 <p>3 to 4-inch screens are generally only suitable for showing a single vertical pane of content at a time, be it a list of items, or detail information about an item, etc. Thus on such devices, screens generally map one-to-one with levels in the information hierarchy (<em>categories</em> &rarr; <em>object list</em> &rarr; <em>object detail</em>).</p>
 
 <p>Larger screens such as those found on tablets and TVs, on the other hand, generally have much more available screen space and are able to present multiple panes of content. In landscape, panes are usually ordered from left to right in increasing detail order. Users are especially accustomed to multiple panes on larger screens from years and years of desktop application and desktop web site use. Many desktop applications and websites offer a left-hand navigation pane or use a master/detail two-pane layout.</p>
