visionCATS’s report templating is based on standard Web technologies. The final report document is a PDF file, but it is first created as an HTML file.
HTML (HyperText Markup Language) defines the content and basic structure of a template. For reference, please see W3Schools HTML.
CSS (Cascading Style Sheets) defines the presentation of a template. For reference, please see W3Schools CSS.
SCSS (Sassy CSS) is a flavor of CSS using Sass preprocessor language to add features like variable. For reference, please see sass-lang.com.

Replaced in new templates by D3.js.

EO.Pdf is a .NET class library for rendering HTML to PDF. It use an embedded Chromium web browser (the base of Google Chrome web browser). Chromium is embedded in one or more process of eowp.exe.
An error in the template could block the rendering to PDF. After 1 minutes, the rendering process will be stopped, and then you should look at the EO.Pdf log and try the report inside a web browser, to determine the error.
Some antivirus may block eowp.exe. Please add eowp.exe to your white list if it is happening.
The Chromium used by EO.Pdf is a recent one, and therefore most modern HTML features should be usable. The actual Chromium version is displayed in About visionCATS (and in report data, by the field
