What Tab Component Designer does and how it behaves

Tabs look trivial to draw and end up inconsistent: this tool builds the whole component - the tab list plus the panels it switches between - in three layouts: a horizontal bar, a vertical column, and a pill-style segmented control. You set the tab labels, the number of tabs, and the colors for active and inactive states, and you get the markup and CSS to paste into a page. The usual surprise is that styling the tabs is only half the job: a tab bar with no panel to open is a row of dead buttons.

How the result is produced

Three layouts, one set of tabs

The three variants are the same set of tabs restyled, so switching a component's layout does not mean re-entering labels or colors. Horizontal lays the labels in a row with the active tab marked. Vertical stacks them in a column with the active tab filled or tinted, the sidebar arrangement. Pill renders a segmented control where the selected tab becomes a filled rounded capsule and the rest stay transparent.

The active state is the product

A tab component runs on one state: which tab is selected. The colors you set describe the active tab, the inactive tabs get the quieter treatment, and only the selected tab's panel is visible. The output keeps the tab list and its panels together, so pasting the snippet gives the whole component, not a decoration. The moving part is the click that moves the selection; everything else is structure.

Good uses

A settings screen with account, privacy, and notification sections as a horizontal tab bar above a content panel.
A dashboard whose left column lists report views as vertical tabs, switching the main panel without navigating away.
A list/grid/map view toggle on a content page using the pill variant as a segmented control.

Limits and checks

Styled tabs are not working tabs. The pasted component still needs the click behavior that moves the selected state, and every tab needs a panel to open; without both, the bar renders but does nothing.
The active tab must not be shown by color alone. If the selected state differs only in hue, it disappears on grayscale and for color-blind users; pair the color with a shape change such as an underline, fill, or weight, and keep the contrast requirements in mind for the indicator.
Tab bars do not shrink gracefully. A horizontal bar sized for five short labels crowds badly with twelve, and the pill variant gets cramped below roughly 320px; plan for scrolling, truncation, or fewer tabs instead of expecting the component to adapt.

Common questions

Does the tool generate the JavaScript that makes the tabs switch?

It produces the component's markup and CSS, which is the designer's job; whether a click handler travels with the snippet is worth checking the moment you paste it. If not, one listener that moves the selected state and shows the matching panel is all a tab bar needs - the markup and styles already define the states it toggles between.

What is the difference between the horizontal and the pill variant?

Same tabs, different active-state language. Horizontal puts an indicator under the selected label and reads as 'section of the page', which suits longer label sets. Pill fills the selected tab as a rounded capsule and reads as a toggle between equal options, which suits short choices like list, grid, and map. Vertical is the same relationship rotated into a sidebar column.
