What is a LESS file?
A .LESS file is a LESS Style Sheet, which stands for Leaner Style Sheets. Created by Alexis Sellier, it is a dynamic style sheet language that extends standard CSS. Web developers use .LESS files to write cleaner, more reusable code. These files include variables, nested rules, and functions. Before a web browser can use them, a compiler like Less.js or a build tool like Webpack must process the .LESS file and convert it into a standard .CSS file.
How to open LESS files?
You can open and edit a .LESS file using any text editor or code editor. Popular choices include Visual Studio Code, Sublime Text, and Notepad++. To compile the code, developers typically use the Less command-line tool or desktop software like Koala.
Identify your file format
Sometimes, a file extension can belong to different software programs. If you do not know the exact origin of your file, viewer.online/less analyzes .LESS files to identify their exact format and creator software. It shows which programs can open the file and usually previews the content directly in your web browser.
Summary
Because .LESS files use the known Source2 format, viewer.online/less can safely open and display them online, eliminating compatibility problems.
