LESS is a CSS preprocessor that is used to extend the capabilities of CSS. CSS, or Cascading Style Sheets, is a stylesheet language that is used to control the appearance and layout of web pages. LESS extends the capabilities of CSS by adding features such as variables, mixins, and functions, which make it easier to write and maintain complex stylesheets.
One of the main benefits of using LESS is that it allows developers to use variables in their stylesheets. This means that they can define a value once, and then reuse it throughout the stylesheet, rather than having to repeat the same value multiple times. This can make it easier to maintain and update stylesheets, as a change to a variable will be automatically applied everywhere it is used.
Another benefit of LESS is that it allows developers to use mixins, which are reusable blocks of styles that can be included in multiple places in a stylesheet. This can make it easier to write and maintain complex stylesheets, as mixins can be used to abstract common patterns and styles, and to avoid repeating the same styles in multiple places.
Overall, LESS is a CSS preprocessor that extends the capabilities of CSS, and makes it easier to write and maintain complex stylesheets. By using LESS, developers can use variables and mixins to improve the organization and maintainability of their stylesheets, and can create more powerful and flexible stylesheets for their web pages.
