  • Course Sass and Less Preprocessing : Content

    In the course Sass and Less Preprocessing participants learn the functionalities of the CSS Preprocessors Sass and Less. Preprocessors are script languages ​​that extend the default capabilities of CSS. This makes it possible to use logic in CSS code with variables, nesting, inheritance, mixins, functions and mathematical operations. CSS preprocessors make it easy to automate repetitive tasks and reduce errors.

    Syntax Sass and Less

    The course starts with a discussion of the basic characteristics of Sass and Less. The Sass syntax with the .scss file extension is discussed. Sass uses standard CSS syntax with braces and semicolons. It is also explained how Less is actually a JavaScript library that requires either NodeJS or compilation using .less files.

    Sass Variables and Types

    Subsequently the variables and types of Sass are discussed and the scope of variables, nested rules and nested properties is explained. And also Sass Plugins are treated.

    Less Variables and Types

    Attention is paid as well to Less variables and types and the syntax of variable interpolation is discussed. The use of mixin's and the parameterization thereof is also part of the program of the course.


    A number of directives can be used in Sass such as @import, @mixin, @include and @extend. The meaning and application of these directives is treated. There is also attention for various Sass functions such as Map, Selector and Introspection.

    Testing Sass and Less

    The course concludes with the subject of testing Sass and Less. This includes the Less Hat, Clearless and 3L libraries.

    Course Forms

    All our courses are classroom courses in which the students are guided through the material on the basis of an experienced trainer with in-depth material knowledge. Theory is always interspersed with exercises.


    We also do custom classes and then adjust the course content to your wishes. On request we will also discuss your practical cases.

    Course times

    The course times are from 9.30 to 16.30. But we are flexible in this. Sometimes people have to bring children to the daycare and other times are more convenient for them. In good consultation we can then agree on different course times.


    We take care of the computers on which the course can be held. The software required for the course has already been installed on these computers. You do not have to bring a laptop to participate in the course. If you prefer to work on your own laptop, you can take it with you if you wish. The required software is then installed at the start of the course.


    Our courses are generally given with Open Source software such as Eclipse, IntelliJ, Tomcat, Pycharm, Anaconda and Netbeans. You will receive the digital course material to take home after the course.


    The course includes lunch that we use in a restaurant within walking distance of the course room.


    The courses are planned at various places in the country. A course takes place at a location if at least 3 people register for that location. If there are registrations for different locations, the course will take place at our main location, Houten which is just below Utrecht. A course at our main location also takes place with 2 registrations and regularly with 1 registration. And we also do courses at the customer’s location if they appreciate that.


    At the end of each course, participants are requested to evaluate the course in terms of course content, course material, trainer and location. The evaluation form can be found at https://www.klantenvertellen.nl/reviews/1039545/spiraltrain?lang=en. The evaluations of previous participants and previous courses can also be found there.
