CSS

CSS (Cascading Style Sheets) is a stylesheet language used to describe the presentation of documents written in HTML or XML, including colors, layouts, fonts, and animations. It enables developers to separate content from design, making web pages more accessible and maintainable. CSS works by applying rules to HTML elements, controlling how they are displayed on various devices and screen sizes.

🧊Why learn CSS?

Developers should learn CSS to create visually appealing, responsive, and user-friendly websites, as it is essential for front-end web development alongside HTML and JavaScript. It is used for styling web pages, implementing responsive designs with media queries, and enhancing user interfaces with animations and transitions. Mastery of CSS is crucial for roles in web design, front-end engineering, and UI/UX development.

ABAP (Advanced Business Application Programming) is a high-level programming language created by SAP for developing business applications within the SAP ecosystem. It is primarily used for customizing and extending SAP ERP (Enterprise Resource Planning) systems, enabling developers to build reports, interfaces, forms, and workflows. ABAP runs on the SAP NetWeaver Application Server and integrates tightly with SAP's database and business logic layers.

ActionScript is an object-oriented programming language originally developed by Macromedia (later acquired by Adobe) for creating interactive content, animations, and applications primarily for the Adobe Flash platform. It is based on ECMAScript, sharing syntax similarities with JavaScript, and was widely used for web-based games, multimedia presentations, and rich internet applications (RIAs). While its usage has declined with the deprecation of Flash, it remains relevant for maintaining legacy Flash content and in niche areas like Adobe AIR for desktop and mobile apps.

Ada is a statically typed, high-level programming language designed for safety-critical and real-time systems, originally developed for the U.S. Department of Defense. It emphasizes reliability, maintainability, and efficiency, with strong support for concurrent programming and formal verification. The language is widely used in aerospace, defense, transportation, and medical devices where failure can have severe consequences.

Agda is a dependently typed functional programming language and proof assistant used for formal verification and theorem proving. It allows developers to write programs with precise types that can encode mathematical properties, enabling the construction of proofs about program correctness. It is based on intuitionistic type theory and is often used in academic and research settings for verifying software and mathematical theorems.

Alloy is a declarative modeling language and analyzer for software design, based on first-order logic and relational algebra. It is used to create lightweight models of systems to explore their behavior and verify properties through automated analysis. The Alloy Analyzer tool generates instances or counterexamples to help developers find design flaws early in the development process.

AMPscript is a proprietary scripting language developed by Salesforce for creating dynamic, personalized content in Marketing Cloud (formerly ExactTarget). It is primarily used within email marketing campaigns, landing pages, and SMS messages to insert data-driven content, perform conditional logic, and manipulate data from Salesforce CRM or other data extensions. The language is server-side processed and embedded directly within HTML content to generate personalized output at send time.
