• Intelligent code autocompletion. The system suggests CSS properties, values, selectors, class names, and HTML tags during typing. Suggestions are based on current web standards and adapt to the context of the written code. The feature reduces syntax errors and speeds up the writing process.
• Code inspection and navigation. An inspection tool analyzes the CSS and HTML structure. It allows quick navigation between rules, selectors, classes, and elements. The code explorer view shows a clear hierarchy of document elements.
• CSS validation and checking. An integrated validator reviews CSS code for syntax errors, unsupported properties, or obsolete usages. The checker flags cross-browser compatibility issues and suggests fixes according to W3C standards.
• Real-time preview. Displays visual results of CSS changes without needing to open an external browser. The preview works with local HTML files and supports multiple display modes, including horizontal or vertical split of the work area.
• Multi-tab and multi-project editing. Allows working simultaneously with multiple CSS, HTML, PHP, XML, or JavaScript files in separate tabs. Supports managing complete projects with folder and file structures. Switching between files is instantaneous.
• Code optimization and cleaning tools. Includes functions to format, compact, and organize CSS and HTML code. Removes unnecessary spaces, combines redundant rules, and reorders properties following predefined configurations. Optimization reduces file size.
• Visual CSS code generation. Allows creating CSS rules through dialogs and forms without writing code manually. Styles for colors, borders, margins, fonts, and visual effects can be defined. The editor automatically generates the corresponding CSS code.
• Macro system and automation. Allows recording sequences of scripts and repetitive tasks to replay them later. Macros can be manually edited and assigned to keyboard shortcuts. Automation covers editing, formatting, and file management actions.
• Integrated FTP/SFTP publishing. Features a built-in FTP client to upload files directly to web servers. Supports secure SFTP connections and allows synchronizing local folders with remote directories. Transfer is performed without external software.
• Workspace customization. Offers multiple color schemes for the code editor, interface themes, and configurable panel layouts. Keyboard shortcuts are modifiable. Developers can adapt the tool arrangement according to their workflows.
• Code snippet manager. Stores and organizes reusable CSS and HTML code snippets. Snippets can be quickly inserted via shortcuts or context menus. The library can be expanded with new categories and custom examples.
• File comparison and merging. A tool to compare two versions of CSS or HTML files and visualize differences line by line. Allows selectively merging changes from one version to another. It is useful for version control and team collaboration.

Rapid CSS Editor was developed by Blumentals Software, a software development company based in Latvia. The program was initially released in 2005. The application is written in the Delphi programming language, using the Embarcadero RAD Studio development environment.
