HTML - 超文本标记语言 (Hyper Text Markup Language)

HTML是建设网站/网页制作主要语言。

HTML是一种易于学习的标记语言。

HTML使用像 <p> 尖括号内标记标签来定义网页的内容:

HTML 实例

<html>
<body>
<h1>My First Heading</h1>
<p>My first paragraph.</p>
</body>
</html>

HTML使用开始标记和结束标记来标记一个网页元素,:在上面的例子, <p>标签标志着一个段落开始,</p>标志着该段末尾。

通过使用简单的HTML标签,网页设计师可以为一个网页(HTML文档)添加标题, 段落,文字,表格,图片,列表,编程代码等。

Web浏览器(IE浏览器,火狐,Chrome等)读取HTML文档,解释HTML标记, 并显示正确用户可读的内容(不显示HTML标签):

根据HTML标准,HTML可用于定义网页的内容。

要定义视觉样式(颜色,大小,外观,布局等),应使用CSS(层叠样式表)(见下一章)。

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.
