CSS RWD Grid View

🎯 한 줄 통찰 (One-line insight)

A grid-view divides the page into rows and columns; using box-sizing: border-box and a display: grid container with named grid-template-areas, you build a layout whose regions can later be rearranged with media queries for different screen sizes. [S1]

🧠 핵심 개념 (Core concepts)

• Grid-view — many web pages are based on a grid-view, which means that the page is divided into rows and columns. [S1]
• box-sizing: border-box — applied to all elements, this makes sure that the padding and border are included in the total width and height of the elements. [S1]
• CSS Grid container — display: grid on a container, combined with grid-template-areas, defines named layout regions (header, menu, main, facts, footer). [S1]
• gap — the container sets spacing between grid items (here gap: 10px). [S1]
• Next step — the page points to adding media queries and breakpoints for different screen sizes in the next chapter. [S1]

🧩 추출된 패턴 (Extracted patterns)

• Named-area layout — assign each block a grid-area name and lay them out by listing those names in grid-template-areas, making the structure readable and easy to rearrange. [S1]
• Universal border-box reset — * { box-sizing: border-box; } removes width-math surprises across the whole document. [S1]

📖 세부 내용 (Details)

What is a Grid-View? Many web pages are based on a grid-view, which means that the page is divided into rows and columns. [S1]

box-sizing The box-sizing property allows us to include the padding and border in an element's total width and height. Applying it to all elements makes sure that the padding and border are included in the total width and height of the elements. [S1]

Complete HTML [S1]

<div class="grid-container">

<div class="header"><h1>Chania</h1></div>

<div class="menu">
  <ul>
    <li>The Flight</li>
    <li>The City</li>
    <li>The Island</li>
    <li>The Food</li>
  </ul>
</div>

<div class="content">
  <h1>The City</h1>
  <p>Chania is the capital of the Chania region on the island of Crete.</p>
  <p>The city can be divided in two parts, the old town and the modern city. The old town is situated next to the old harbour and is the matrix around which the whole urban area was developed.</p>
  <p>Chania lies along the north west coast of the island Crete.</p>
</div>

<div class="facts">
  <h2>Facts:</h2>
  <ul>
    <li>Chania is a city on the island of Crete</li>
    <li>Crete is a Greek island in the Mediterranean Sea</li>
  </ul>
</div>

<div class="footer"><p>A footer.</p></div>

</div>

By default this single-column stacking layout (header, menu, main, facts, footer) is the mobile/base view; the next chapter adds media queries and breakpoints to rearrange these areas for larger screens. [S1]
