THE ANSWER / PLAIN ENGLISH

The idea to remember.

Structured data describes the type of page and information it contains, helping search engines interpret the content. It must accurately describe visible material and does not guarantee a rich search result.

01Learn by doing

From first example to real project.

Start with the smallest working idea, examine a more detailed example, then look at a real application pattern. Adapt dependencies, error handling and data models to your project.

Basic: meaningful markup

01 / BEGINNER

Native HTML elements give browsers and assistive tech useful semantics.

HTML / EXAMPLE

<nav aria-label="Main navigation">
  <a href="/explore/questions">Interview questions</a>
</nav>
<main><h1>React interview guide</h1></main>

Intermediate: responsive CSS

02 / INTERMEDIATE

Use a fluid layout rather than fixed desktop widths.

CSS / EXAMPLE

.cards { display: grid; grid-template-columns: repeat(auto-fit, minmax(min(100%, 18rem), 1fr)); gap: 1rem; }
.card { min-width: 0; }

Real scenario: accessible search form

03 / REAL SCENARIO

Connect the visible label and the input; communicate updated results.

HTML / EXAMPLE

<form role="search">
  <label for="search">Search questions</label>
  <input id="search" type="search" autocomplete="off" />
</form>
<p role="status" aria-live="polite">24 matching articles</p>

02Check your understanding

Try it in your own words.

Explain what does structured data add to technical articles without looking at the code. Then modify the intermediate example, describe one trade-off and identify when the real-world pattern fits.
