1# Bottom Tab 2 3Bottom tabs, as a common navigation component, allow users to quickly access different functions of an application. 4 5 6 7 8## How to Use 9 10- Use bottom tabs only on level-1 screens to provide quick switch between different tab pages. 11 12- Place bottom tabs at the bottom of the screen to reflect the level-1 categories of an application. These categories are presented in an equal manner. This practice allows users to perform actions with one hand. 13 14- Use the combination of an icon and a text for each bottom tab. When users touch a tab, the tab is activated and highlighted. 15 16- Use a siderbar rather than bottom tables on tablets in landscape mode so that your users can perform actions with both hands. 17 18- Use concise text on each bottom tab. 19 20 21- Use two to five bottom tabs to avoid an overwhelming layout. 22 23- Use badges on bottom tabs to notify users of new unread information.
