Less runs on both the server-side (with ppti.info and Rhino) or client-side ( modern browsers only). Because Less looks just like CSS, learning it is a breeze. Libby A.

It takes a lot of effort and discipline to keep your CSS maintainable. But it doesn't have to be this way. Luckily, the web development community has solved this problem. They give us a number of benefits over plain CSS:. The negative aspect is that if you use one of these pre-processors, you will need to compile your stylesheets down to regular CSS so that it works in browsers.
If you have node installed, and you know what a terminal is, go ahead and open one. Then install less using NPM:. This will give you access to the lessc command from any open terminal, enabling you to compile your. Let's say we've written all our stylesheet rules with LESS in styles. With the above line, our code will be transformed to plain CSS in styles.
All that is left is to link this css file our HTML. If there was a compilation mistake, it will show up in your terminal. One of the main features of Less is the ability to create variables just like you would in a standard programming language.
They can store any type of value you find yourself using frequently: The philosophy of less is to reuse the CSS syntax where possible. Here, we define two variables, one for background color and one for text color, both containing hexadecimal codes.
Switch between the tabs to see the translated to CSS version of the code:. In the example above, the background color is white, while the text is dark. If, let's say, we want to switch them around and have dark elements with white text, we can simply change the values of the variables, instead of manually replacing every occurrence.
For more about variables in Less read here.
LESS enables us to use an existing class or ids and apply all it's styles directly to another selector. The following example will clear things up:. Another cool thing mixins can do is receive parameters.
In the following example we add an argument for the width and height of our circles, with a default value of 25 pixels. This will create a small circle 25x25 and a big one x pixels.
Read more about Less mixins in their official documentation. Nesting can be used to structure your stylesheet in a way that matches the HTML structure of the page, while reducing the chance of conflicts.
Here is an example of an unordered list and its children:. Just like in programming languages, in Less variables receive their values depending on the scope.

If the value isn't specified in the specific scope, LESS will look for it in upper blocks until it finds the nearest declaration. Learn more about scope here. You can do basic math operations to numerical values and colors. Lets say we want to have two divs placed next to each other, the second one being twice as wide and with a different background.
LESS knows what the measuring units are and won't mess them up. LESS has functions too! It's starting to look more and more like a programming language, isn't it? This is called bubbling. 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. It would not be meaningful in most cases - a length multiplied by a length gives an area and css does not support specifying areas. Less will operate on numbers as they are and assign explicitly stated unit type to the result. This is currently the fourth year an edition has been released.
