About formats

CDT (CorelDRAW Template) is a template file format used by CorelDRAW, Corel Corporation's vector graphics editor available since January 1989. A CDT file is structurally identical to a standard CDR document — sharing the same RIFF-based container, vector object types, color definitions, and page layout capabilities — but is designated as a reusable starting point for new designs rather than a finished artwork file. When opened in CorelDRAW, a CDT creates a new untitled document pre-populated with the template's content, leaving the original template unchanged for repeated use. This workflow mirrors the template model found in office productivity suites, adapted for graphic design. CDT files commonly contain pre-built layouts for business cards, brochures, letterheads, certificates, posters, and other standardized print materials, complete with placeholder text, guide lines, bleed areas, and properly configured color spaces for print output. One advantage is workflow consistency — design teams can distribute branded templates ensuring every new document starts with correct dimensions, margins, fonts, and color palettes aligned to corporate identity standards. The format also saves significant setup time: rather than configuring document properties and recreating layout elements from scratch, designers begin with a production-ready foundation. Corel ships hundreds of CDT templates with CorelDRAW installations, and the format is supported across CorelDRAW versions with the same compatibility considerations as CDR.

HTML (HyperText Markup Language) is the standard markup language for creating web pages, originally conceived by Tim Berners-Lee at CERN in 1991 and later standardized by the W3C and WHATWG. HTML structures content using a system of nested tags that define headings, paragraphs, lists, links, images, tables, forms, and multimedia elements, with CSS handling visual presentation and JavaScript adding interactivity. The language has evolved through major versions — HTML 2.0 (1995), HTML 4.01 (1999), XHTML 1.0 (2000), and the current HTML Living Standard (evolved from HTML5, published 2014) — each expanding semantic vocabulary and capabilities. HTML documents are plain text files interpretable by any web browser, and the language's role extends beyond websites: email formatting, ebook content (EPUB), application interfaces (Electron, Cordova), and document export all rely on HTML. One advantage is universal rendering — every computing device with a browser displays HTML content, making it the most widely supported document format in existence. The semantic markup model provides another strength: elements like <article>, <nav>, <aside>, and <figure> carry meaning that benefits accessibility tools, search engine indexing, and content reuse. The open, W3C/WHATWG-governed specification ensures vendor independence, and HTML's text-based nature means documents are trivially created, inspected, and processed with any programming language.
