A responsive React portfolio is built by composing reusable interface components, choosing a styling approach, and checking that the layout and interactions work at narrow and wide viewport sizes. The exact project named “How I Built a Responsive React.js Portfolio Website” could not be verified, so this guide does not claim a particular design, codebase, breakpoint, or device test. Instead, it lays out a practical build path and identifies where your own project choices belong.
Choose how to start the React app
For a new React application, React recommends starting with a framework. Building from scratch can still make sense when you are learning the fundamentals or when a project constraint calls for it. React’s Creating a React App guidance discusses both paths.

Use a framework for a new application
A framework provides an established foundation for application concerns. Pick one that fits the needs of your portfolio rather than assuming every project should use the same setup.

Use a build tool when building from scratch fits
React’s from-scratch guidance lists Vite, Parcel, and Rsbuild as build-tool options. This route gives you a client-only single-page app, so you must make additional choices for routing, data fetching, and styling. React does not require a particular build tool or styling method.

If you want to explore React before installing software, the official Installation guide points to browser-based sandboxes. It also explains that React can be added to an existing site or used to create an app.
Plan the portfolio as components
React describes components as reusable, nestable pieces of UI, commonly written as JavaScript functions that return markup. Start by dividing the portfolio according to its real content and behavior rather than making a separate component for every visual detail. A typical portfolio might have a page shell, navigation, introduction, project list, project card, and contact area; treat these as examples to adapt, not verified parts of the titled project.
Keep a component focused enough that its purpose is clear. A project card, for example, can receive a project’s title, summary, image, and destination as data. The parent list can render multiple cards from a collection. If a value or interaction is shared across several components, decide where it belongs and pass it where needed.

Use those patterns to make content and interaction explicit rather than duplicating markup or hard-coding each card separately.
Choose a styling approach and design for different widths
React does not prescribe a CSS approach. You can include CSS through a simple HTML link or through your chosen build tool or framework; the right choice depends on how you want to organize and maintain the project. Name the method your implementation actually uses instead of implying that React requires a particular one.
Responsive behavior comes from the layout rules you write, not from using React. Decide how content should reflow as available space changes: for example, whether project cards stack or form columns, how navigation remains usable, and whether images scale without overflowing. Use fluid rules where they suit the content and add breakpoints only where the design needs a different arrangement. There is no verified breakpoint value for the specific project referenced by the title.
Check the actual page at narrow and wide viewport sizes. Confirm that text remains readable, images fit their containers, controls can be reached and used, and content does not become hidden or create unwanted horizontal scrolling. If navigation changes form on small screens, verify how that interaction opens, closes, and behaves with keyboard focus. Describe only the viewport checks you performed; a responsive claim should not stand in for evidence of testing.

Connect portfolio content to interactions
Keep project information in a data structure when the same presentation repeats. Render the collection as a list, and use a stable key for each item as required by React’s list-rendering pattern. Conditional rendering can handle optional details, such as omitting a link when a project has no public destination.
Best Value
Make interactive elements do what their labels promise. A navigation control should take the visitor to its intended destination, and a contact action should have a clear outcome, such as opening the chosen contact method. The exact project data, navigation behavior, and contact implementation are not established for this title; document the behavior your code actually provides.
Inspect the finished interface
React Developer Tools is an optional browser debugging aid. According to the official React Developer Tools guide, it can inspect components, edit props and state, and help identify performance problems. These capabilities can help during development, but using the tool does not by itself establish that an app was profiled or tested.
Before publishing, review the page as a visitor: follow the project links, try the navigation and contact interaction, and check the layout at the viewport sizes that matter for your audience. Record what you checked and avoid claiming device coverage or performance results you did not measure.
