Bold text

Italic text

Computer automatic output is subscript and superscript

HTML formatting label

HTML uses tags < b > (“bold”) and < I > (“italic”) to format the output text, such as bold or italics

These HTML tags are called formatting tags (see the complete tag reference manual at the bottom).

Usual label <strong> replace bold label <b> to use <em> replace <i> label use. However, the meanings of these labels are different: <b> and <i> defines bold or italic text. <strong> or <em> means that the text you want to present is important, so highlight it. All major browsers today can render fonts with various effects. However, browsers may support better rendering in the future.

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.
