It is beneficial when you want to outline a mixin that abstracts out both wrapping a piece of code within a media query or perhaps a non-supported browser class name. The rulesets is often handed to mixin so which the mixin can wrap the written content, e.g.

When a @plugin phone operates well for some situations, there are occasions when you should load a plugin ahead of parsing commences.

The extend is both hooked up to some selector or positioned right into a ruleset. It seems like a pseudo-class with selector parameter optionally accompanied by the key word all:

Food 4 Less gives a various array of new fruits and vegetables, enabling you to try to eat healthily with no breaking the lender.

A ruleset may be now assigned to a variable or passed in to a mixin and can contain the entire set of Less features, e.g.

In order to avoid any unintentional joins, merge calls for an explicit + or +_ flag on Every join pending declaration.

However, you would wish to return an appropriate Less node when you wished to, say, multiply that towards other values or do other Less operations. Otherwise the output in the stylesheet is basic text (which may be great in your needs).

The real key may be the when key word, which introduces a guard sequence (in this article with only one guard). Now if we run the next code:

Setting up in Less three.5, You can utilize home/variable accessors to pick a value from an evaluated mixin's rules. This could certainly assist you to use mixins comparable to features.

If a ruleset has numerous selectors, any of these can possess the increase key phrase. Various selectors with lengthen in a single ruleset:

Variables defined instantly in callers scope can not be overridden. Having said that, variables described in callers dad or mum scope is not really shielded and may be overridden:

Extend by default appears to be like for exact match amongst selectors. It does matter no matter whether selector uses major star or not. It doesn't matter that two nth-expressions hold the exact which means, they should really have to exact same kind so that you can be matched.

Right here the desktop-and-previous-ie mixin defines the media query and root class to be able to make use of a mixin to wrap a piece of code. This tends to output

Namespacing your mixins similar to this decreases conflicts with other library mixins or person mixins, but may also be a means to "organize" groups here of mixins.
