Block grids are used to divide the content of the page equally: for example, to display four pictures in a row, you need to divide the width equally no matter what the screen is.

Can be used <ul> Element plus .small|medium|large-block-grid-num Class to create a block mesh. num Used to specify that the average score is the quantity:

8.36.1. Example

<ul class="small-block-grid-3">
  <li><img src="newyork.jpg" alt="New York"></li>
  <li><img src="paris.jpg" alt="Paris"></li>
  <li><img src="sanfran.jpg" alt="San Francisco"></li>
</ul>

For another example, use paragraphs:

8.36.2. Example

<ul class="small-block-grid-3">
  <li><p>Just a Simple Example Text...</p></li>
  <li><p>Just a Simple Example Text...</p></li>
  <li><p>Just a Simple Example Text...</p></li>
</ul>

Different sizes of screens show different quantities.

You can set different sizes of screens to display different numbers of blocks by adding multiple grid block classes:

8.36.3. Example

<ul class="small-block-grid-2 medium-block-grid-3 large-block-grid-4">
  <li><img src="newyork.jpg" alt="New York"></li>
  <li><img src="paris.jpg" alt="Paris"></li>
  <li><img src="sanfran.jpg" alt="San Francisco"></li>
  <li><img src="newyork.jpg" alt="New York"></li>
</ul>

Principles, Technologies, and Methods of Geographic Information Systems  102

In recent years, Geographic Information Systems (GIS) have undergone rapid development in both theoretical and practical dimensions. GIS has been widely applied for modeling and decision-making support across various fields such as urban management, regional planning, and environmental remediation, establishing geographic information as a vital component of the information era. The introduction of the “Digital Earth” concept has further accelerated the advancement of GIS, which serves as its technical foundation. Concurrently, scholars have been dedicated to theoretical research in areas like spatial cognition, spatial data uncertainty, and the formalization of spatial relationships. This reflects the dual nature of GIS as both an applied technology and an academic discipline, with the two aspects forming a mutually reinforcing cycle of progress.
