Variable Interpolation
LESS also permits us to perform operations corresponding to addition, subtraction, multiplication and division to quantity, colour and variable in the style sheet. By combining namespacing with the lookup syntax, you’ll have the ability to flip your rulesets / mixins into maps. Starting in Less 3.5, you need to use property/variable accessors (also called “lookups”) to select a worth from variable (detached) rulesets. Notice, not like mixins utilized in root, mixin calls assigned to variables and referred to as with no arguments all the time require parentheses. Beginning in Less three.5, you can use property/variable accessors to select a worth from an evaluated mixin’s guidelines.
Variables In Less
Use @import (optional) to allow importing of a file only when it exists. Without the elective keyword Less throws a FileError and stops compiling when importing a file that may not be found.

- It allows us to type properties of HTML elements utilizing selectors.
- Instead of manually running the ‘lessc’ command every time we wish to compile our code, we will set up a task runner.
