Introduction
The World-Wide Web is a set of computer technologies that publish and view information over the Internet in a highly interactive manner.
This information, commonly text and images, is structured using the HyperText Markup Language (HTML) and styled using Cascading Style Sheets (CSS).
Additional types of content can be used with HTML, in particular Scalable Vector Graphics (SVG) for displaying geometric shapes (similar to Adobe Illustrator).
Geographic data such as basemaps or digital elevation models can be displayed using images.
Geographic data in the form of points, lines, and polygons can be displayed using SVG.
CSS can be used to properly position and overlay different geographic data sets, assuming they have the same coordinate system.
In this chapter we will learn about these static languages of the Web and how they form the foundation of Web-based GIST.
