What HTML-Kit is

HTML-Kit is a Windows editor for creating and maintaining HTML, XHTML, and XML pages. It can edit, format, validate, preview, and publish web pages, while also handling CSS, JavaScript, PHP, Python, Ruby, Java, and SQL files. Editing tools include syntax highlighting, multiple-document editing, customizable keyboard shortcuts, auto-complete, and spell checking. Preview choices include an internal view, an external browser, side-by-side display, and offline preview. Its Workspace reaches local files, network drives, and FTP servers, including remote files that can be opened, edited, and saved online or offline. Validation covers HTML and XML, HTML Tidy, and online HTML and CSS validators. Named integrations include CSE HTML Validator, TopStyle Lite, Windows shell, and email clients. Third-party plugins use an open plugins interface, and the features page describes hundreds of optional free add-ins. A free plan is available, while the HTML-Kit Tools full version includes full-version access and a 30-day refund policy.
