Language Features Less. Edit the markdown source for features overview. As an extension to CSS, Less is not only backwards compatible with CSS, but the extra features it adds use existing CSS syntax. This makes learning Less a breeze, and if in doubt, lets you fall back to vanilla CSS. Variables. These are pretty self explanatory nice blue 5. B8. 3AD. light blue nice blue 1. Outputs header. Note that variables are actually constants in that they can only be defined once. Mixins. Mixins are a way of including mixing in a bunch of properties from one rule set into another rule set. So say we have the following class. And we want to use these properties inside other rule sets. Well, we just have to drop in the name of the class where we want the properties, like so menua.

Less gives you the ability to use nesting instead of, or in combination with cascading. Lets say we have the following CSS header. In Less, we can also write it this way header. The resulting code is more concise, and mimics the structure of your HTML. You can also bundle pseudo selectors with your mixins using this method. Heres the classic clearfix hack, rewritten as a mixin represents the current selector parent. See also. Nested Directives and Bubbling. Directives such as media or keyframe can be nested in the same way as selectors. Directive is placed on top and relative order against other elements inside the same ruleset remains unchanged. This is called bubbling. Conditional directives e. Media, supports and document have also selectors copied into their bodies. Remaining non conditional directives, for example font face or keyframes, are bubbled up too. Their bodies do not change a. Operations. Arithmetical operations, can operate on any number, color or variable. If it is possible, mathematical operations take units into account and convert numbers before adding, subtracting or comparing them. The result has leftmost explicitly stated unit type. If the conversion is impossible or not meaningful, units are ignored. Example of impossible conversion px to cm or rad to. Multiplication and division do not convert numbers. It would not be meaningful in most cases a length multiplied by a length gives an area and css does not support specifying areas. Manhattan/300/otf_files%2F000%2F007%2F620%2F7620%2Foriginal%2FVariable_black?trim=false' alt='Variable Black Font Free' title='Variable Black Font Free' />Less will operate on numbers as they are and assign explicitly stated unit type to the result. Colors are split into their red, green, blue and alpha dimensions. The operation is applied to each color dimension separately. E. g., if the user added two colors, then the green dimension of the result is equal to sum of green dimensions of input colors. If the user multiplied a color by a number, each color dimension will get multiplied. Note arithmetic operation on alpha is not defined, because math operation on colors do not have standard agreed upon meaning. Do not rely on current implemention as it may change in later versions. An operation on colors always produces valid color. If some color dimension of the result ends up being bigger than ff or smaller than 0. If alpha ends up being bigger than 1.

Escaping allows you to use any arbitrary string as property or variable value. Anything inside anything or anything is used as is with no changes except interpolation. Functions. Less provides a variety of functions which transform colors, manipulate strings and do maths. They are documented fully in the function reference. Using them is pretty straightforward. The following example uses percentage to convert 0. Namespaces and AccessorsNot to be confused with CSS namespace or namespace selectors. Sometimes, you may want to group your mixins, for organizational purposes, or just to offer some encapsulation. You can do this pretty intuitively in Less, say you want to bundle some mixins and variables under bundle, for later reuse or distributing bundle. Now if we want to mixin the. Note that variables declared within a namespace will be scoped to that namespace only and will not be available outside of the scope via the same syntax that you would use to reference a mixin Namespace. So, for example, you cant do the following Namespace this will not work. The Greatest Film Never Made, 2012 Fiona Banner and Fraser Muggeridge Graphite on paper 139. Scope. Scope in Less is very similar to that of programming languages. Variables and mixins are first looked for locally, and if they arent found, the compiler will look in the parent scope, and so on. Variables and mixins do not have to be declared before being used so the following Less code is identical to the previous example var red. See also. Comments. Both block style and inline comments may be used var red. Importing. Importing works pretty much as expected. You can import a. The extension is optionally specified for.
