Stylus is a dynamic stylesheet pre-processor language that is compiled into Cascading Style Sheets (CSS). The design is influenced by SASS and LESS. It's regarded as the fourth most used CSS pre-processor syntax, it is an upgrade to a conventional CSS files where, we can omit the usage of many characters such as braces, punctuations such as semi-colons, etc. this reduces the burden on the user to write the code in a much easy way when compared to writing a CSS file.
