Sass allows us to nest selectors within one another, making our code easier to read and organize. For example, we can nest a hover state for a button within the button selector. Remember that Sass is, above everything, a way to write CSS code more efficiently.
The add function takes two arguments, $x and $y, and returns the total of those two numbers. The container class width property is then set to the result of running the add function with the arguments 100px and 50px. Ultimately, Sass is a helpful tool for web developers since it makes developing CSS more straightforward, efficient, and error-free. User interface design contains many elements for developers to master.
How does Sass work?
Using Sass, you can take advantage of features like variables, nesting, mixins, and functions to develop styles more quickly and easily and keep your code organized and modular. Furthermore, Sass can be used together with CSS frameworks like Bootstrap and Foundation to help streamline the development process. As you’ll learn in a moment, Sass allows for variables and chunks of code that what is sass in web development can be reused over and over again. This saves developers a lot of time and reduces the risk of coding mistakes. It also makes it easier and faster to change styles in multiple places in your code, such as frame sizes, border styles, colors, and so on. A mixin is a group of CSS declarations that can be reused throughout your stylesheet, similar to a function in a programming language.
The idea here is not to learn everything about Sass but what you see is mostly what you need to know to start using Sass. Style.scss is the source file and style.css is the destination file where Sass generates the CSS code. Finally, Sass is compiled to CSS and adds all the necessary vendor prefixes so you don’t have to worry about writing them manually.
Mixins:
Since SASS extends the functionality of CSS providing a range of powerful features, it makes it easier to manage and organize your stylesheet code. One of the key benefits of SASS is the ability to use variables and mixins. Most people with programming experience are familiar with writing functions or methods in their programs; however, traditional CSS files do not support this feature. Fortunately, Sass allows developers to write mixins, or a group of CSS declarations that are grouped together and can be used repetitively anywhere on your stylesheet. A mixin is essentially the equivalent to a function; it can accept an input value and plug it into the CSS declarations grouped inside the mixin. To create a mixin, simply write @mixin mixinName(value) followed by the CSS declarations that use the inputted value.
To create a partial file, you need to use an ‘underscore’ before the file name. For instance, you can name a file like “_font.sass.” The underscore indicates to the SASS pre-processor that the file is a partial SASS file and should not be compiled. You can include all the details you want in this file and use them in other SASS files to compile it.
The Ultimate Guide to Top Front End and Back End Programming Languages for 2021
To provide some context for this article, I must first elaborate on some details. I am currently in the process of pursuing a career as a web developer, which I began just three months ago. Despite having no prior experience in programming or website development, I decided to embark on this journey because I felt strongly drawn to the field. That said, it is clear that both SASS and LESS play vital roles in the world of development.
- It is fairly easy to learn LESS because it looks just like CSS.
- Because Sass code is reusable, you can save time when building a webpage by referencing past code.
- There are a few reasons (discussed below) that make using SASS efficient for front-end developers.
- The advantage of SCSS is that you don’t need to convert an SCSS file to CSS since all SCSS syntax is also valid in CSS.
- For a more thorough guide of these features and how to implement them in your code, visit the official guide on the Sass website.
- Now, Sass developers can use @if and @else directives which will lead to much more powerful website development.
This allows us to reuse and change values in one place rather than having to update them throughout the code. It’s also easier to learn SCSS syntax if you’re used to CSS already. While SCSS syntax looks more like native CSS, both SCSS and the original Sass syntax can perform the same functions in Sass. Both syntax styles allow you to use variables, Mixins, functions, and other features not available in native CSS.

After you have finished designing your HTML elements using Sass, it is time to finally publish your website. However, you cannot directly use the SCSS files when loading your website. With the Sass gem, which can be installed through the command line, there a variety of executables available. If you do not have the Sass gem installed, you may also run the Sass executables with another source. In an earlier post, we covered getting set up with Sass and being able to convert your files to standard CSS.
This variable is used to set the radius value for each element. While it provides an excellent method for reducing the amount of code you need to write, it can also lead to over-qualified CSS if not executed carefully. The idea is to nest your CSS selectors in such a way as to mimic your HTML hierarchy. The underscore (_) in this example indicates that this file is partial and should not be compiled into a separate CSS file. Partials are Sass files that should be included in other files but not compiled independently.
How to Install and Configure Sass
Sass is an extension of CSS3, adding nested rules, variables, mixins, selector inheritance, and more. It’s translated to well-formatted, standard CSS using the command line tool or a web-framework plugin. It’s particularly useful in large development projects where it quickly becomes difficult to manage multiple style sheets. Front-end developers and UX designers will likely encounter the application of Sass in their day-to-day job responsibilities and development projects. Sass encourages this modular workflow by using what is referred to as partials.
While there are numerous options for choosing how to compile the popular Sass preprocessor into regular CSS, a compiler that utilizes the LibSass engine has increasingly become more common. This tutorial will introduce the Sass programming language and also provide a step-by-step guide to using the node-sass wrapper to compile your Sass code, directly as an npm script. Note that node-sass is intended to be used with .scss files rather than .sass, the former being the more common and popular option. Overall, SASS provides a powerful set of tools for managing and organizing your stylesheet code, making it an essential tool for modern web developers. Imagine you are working on a large-scale web development project that involves multiple developers and a complex set of design requirements. This is where SASS (Syntactically Awesome Style Sheets) comes in.
How to Learn Sass
In this post, I will cover the very basics of SASS, not dwelling into any code since most people are not using a pre-processor for CSS, so a need for its use needs to be understood first. If you try to run the index.html file, nothing will change. It does not change because we have created files that are not related to index.html and our style.sass file only generates the code it has. Since we are https://www.globalcloudteam.com/ working with a Sass file and HTML does not recognize Sass, to see the results we’ll specify the CSS file that has been generated in our file index.html. Because it cuts down on the amount of code you need, it can make it look cleaner and more concise. While nesting is great for making your CSS more organized and readable, overly nested code can be hard to maintain once it’s compiled into CSS.
