React Tailwind Component Builder with Live Preview

What is the React Tailwind Component Builder?

The React Tailwind Component Builder is a free browser tool that generates a React component styled with Tailwind CSS. A person picks a component type, such as a button or a text input, adjusts a few style options, and the tool shows a live preview next to the matching JSX code. Everything runs in the browser. No account or server call is needed.

Component types

The tool can generate five kinds of components:

• Button — a clickable button with custom text
• Text input — a single-line form field with placeholder text
• Textarea — a multi-line form field with a set number of rows
• Select — a dropdown list built from a list of options
• Breadcrumb — a row of links showing a page's location in a site, such as Home / Products / Category

Which properties can be changed

Five style properties apply to every component type:

• Text color — white, black, gray, blue, red, or green
• Background color — none, white, light gray, blue, red, or green
• Padding (inner spacing) — none, small, medium, large, or the button default
• Border radius (corner rounding) — none, small, medium, large, or fully rounded
• Width — auto, full, one half, one third, or one quarter

Some properties only appear for certain component types: the button's text, the placeholder text on a text input or textarea, the number of rows on a textarea, the list of options on a select, and the list of items on a breadcrumb. Text inputs, textareas, and selects also have "required" and "disabled" checkboxes; buttons have a "disabled" checkbox too.

Four properties are fixed and cannot be changed through the interface: margin (always m-0), border style (always border border-transparent), font size (always text-base), and font weight (always font-medium). Every generated component carries these same four classes. To use a different margin, border, or font size, edit the copied code by hand.

How the generated class list is built

The tool builds the Tailwind class string for each component in a fixed order:

1. Text color class, if one is set
2. Background color class, if one is set
3. Padding, margin, border, and border-radius classes
4. Width class, unless width is set to "auto"
5. The fixed font-size and font-weight classes
6. Classes for interactive states (hover, focus, active), which differ by component type
7. Classes for the disabled state, if "disabled" is checked

Buttons get hover:bg-opacity-90, focus:ring-2, focus:ring-offset-2, and focus:ring-blue-500. A button that is not disabled also gets cursor-pointer. Text inputs, textareas, and selects instead get focus:outline-none, focus:ring-2, focus:ring-blue-500, and focus:border-blue-500. Breadcrumbs get none of these interactive classes, and the disabled state never applies to a breadcrumb, since a navigation list cannot be disabled.

Example: button

With the default settings (white text, blue-500 background, medium padding, rounded corners) the tool outputs:

Example: text input

With gray text, a white background, small padding, large border radius, full width, and "required" checked:

Example: textarea and select

Textareas and selects follow the same class-building rule as text inputs. A textarea with black text, medium padding, medium rounding, full width, and 4 rows:

A select with the same colors and spacing as the text input example above, and three options:

Example: breadcrumb

Breadcrumb links and separators always use fixed classes (hover:text-blue-600 on links, mx-2 text-gray-400 on the "/" separator). Only the outer list picks up the five shared style properties. With gray text and no padding or rounding:

Responsive preview versus responsive classes

The tool has a "Responsive View" control with three options: mobile, tablet, and desktop. Switching between them only changes the width of the preview box, so a person can see roughly how a component would look on a narrower screen. It does not add any Tailwind breakpoint prefix, such as sm:, md:, lg:, or xl:, to the generated code. The JSX output is the same regardless of which responsive view is selected. Anyone who needs a component to look different at different screen widths must add those breakpoint classes to the copied code themselves.

How to add Tailwind CSS to a React project

1. Install the packages: npm install -D tailwindcss postcss autoprefixer
2. Set up the config files: npx tailwindcss init -p
3. List the project's source files in tailwind.config.js under content
4. Add the three Tailwind directives to the main CSS file: @tailwind base; @tailwind components; @tailwind utilities;
5. Paste a generated component into a React file

Frequently asked questions

What does the React Tailwind Component Builder do? It generates a styled React component and its matching Tailwind CSS classes, and shows a live preview while a person adjusts the settings.

Does the tool add responsive breakpoint classes like sm: or md: automatically? No. The mobile/tablet/desktop control only resizes the preview box. The exported code has no sm:, md:, lg:, or xl: classes; these must be added by hand if needed.

Can I change the margin, border style, or font size? Not through the interface. Every generated component uses the same fixed margin (m-0), border (border border-transparent), font size (text-base), and font weight (font-medium). Change these by editing the copied code directly.

Does the tool save my components? No. There is no save feature. Copy the generated code and store it in the project's own files.

Does it generate TypeScript? The tool outputs JSX (JavaScript syntax). The output is plain JSX markup, so it can be pasted into a .tsx file without changes, though no type definitions are generated.

Is the tool free to use? Yes. It runs entirely in the browser, with no account and no request sent to a server.

Does it work with Next.js, Gatsby, or other React frameworks? Yes. The generated code is plain JSX with Tailwind classes, so it works in any React-based framework that has Tailwind CSS configured.
