If you want to make your career as a Frontend Developer, knowing HTML, CSS, and JavaScript is essential. Numerous individuals who learn CSS (Cascading Style Sheets) go up to Sass (Syntactically Awesome Style Sheets) to gain more efficiency and consistency in web designing, notably in big, complex, and web development projects. At the same time, Sass is an extension of CSS and a style sheet language. CSS alone is not sufficient for a smooth coding experience.
Thus, if you are looking forward to beginning with Sass development but are confused about where to start, you will get a complete guide to Sass development in this article. Not just the definition of Sass development, you will also find out Sass uses, how it works, and the fundamental aspects of learning it.
What is Sass Development?
Sass is an extension tool of CSS, also referred to as the preprocessor. It is also a scripting language and is interpreted into CSS. The primary function of style sheet languages is to maintain and control the appearance of text on a webpage. It also controls the color, menu position, and frame size of text content.
CSS features are utilized in all the web pages, yet using Sass would make the coding experience even more accurate and smooth. Sass was mainly built to assist the developers in writing instructions related to the present text on screen, not just working on variable or complex design tasks.
CSS comes with a few downsides that Sass can easily overcome and prevents developers from wasting excess time and effort on the projects. Sass is used in various ways. We will be discussing the same here in this article later.
Further, Sass was mainly written in Ruby and ported into various languages like C, C++, JavaScript, Java, .NET, PHP, Python, and Scala.
Here are some essential tools of Sass to be utilized by developers;
- Compass-style.org - It is an open-source CSS authoring system.
- Sassmeister.com - It is more like the playground for compass, LibSass, and Sass.
- mhs.github.io/scount-app - Sass and compass are run in a self-contained Ruby environment by Scout. It allows hassle-free managing of all Sass projects with some clicks.
- Bourbon.io - It is a streamlined and lightweight mixins library for Sass.
- Susy.oddbird.net - It is a Sass-based grid system.
- Css2sass.herokuapp.com - It acts as a converter from CSS to Sass/SCSS.
- github.com/brigade.scss-lint - To maintain, clean, and make readable SCSS files, this tool is used.
- Sassdoc.com - One can create excellent and powerful docs with this documentation system tool.
- sass-guidlines.es - Developers can write sane, maintainable, and scalable Sass with this opinionated style guide.
Why Use Sass?
Compared to CSS, Sass is utilized and preferred by web developers. It takes a bit of time to learn and understand the Sass carefully. That's why developers usually prefer Sass over CSS. Moreover, there are numerous reasons to use Sass, and that’s why developers learn Sass.
Reasons to use Sass are:
1. More organized codes as compared to the CSS
Usually, the CSS and Sass come with numerous abilities theoretically. However, a developer can perform the same task with less coding with Sass as compared to CSS. This is the reason that makes Sass more understandable and reliable, specifically for big web projects that need multiple developers to work.
2. Easy Syntax to learn
If you are already into CSS, it would be great to discover that Sass has the same syntax as CSS. However, you can find some different syntax too. Hence, developers who already know CSS with a brief program prefer to go with Sass. They consider Sass as more of a programming language, but not as the whole language.
3. Sass codes are reusable
Sass contains some variables and chunks of code that could be used again and again easily. This reusability helps the developer perform projects fast, and it also minimizes code mistakes during the project. Moreover, this property also helps change the styles more accurately and quicker in various places in code.
4. Sass is more stable
It was launched in 2006; since then, Sass has been supported by its manufacturers and core developers, and some giant tech companies. Hence, today Sass has become one of the matured, latest, and most advanced programming languages.
How does Sass Work?
Now, you must have understood what exactly is Sass development, and its usage in web development projects. Further, it is essential to understand the working behavior of Sass or how it works. Which leads to a better understanding of this language before beginning with it.
Sass is usually a preprocessor language that is deciphered into CSS. A preprocessor language takes input information and converts it to a result utilized as a contribution by another program. Although, it states that when you run Sass code, you are converting your code to CSS. Further, the browser directly utilizes the CSS code output. It is necessary to use this code conversion, as the browser typically understands the CSS code.
Let’s now discuss the advanced features of Sass that developers like to utilize.
Features of Sass
As you may be suspecting, the code conversion manner in which Sass works implies there's nothing you can code in Sass that you were unable to code straightforwardly in CSS.
However, Sass incorporates a couple of particular highlights that assist developers with coding efficiently.
1. Sass has variables
Repeating behavior is the thing developers dislike while working. Assume that you're making a website with various pages. You'd need multiple pages to look and feel associated by having steady color schemes and fonts. CSS demands colors and font styles on each page every time. Also, assuming you needed a new color scheme, you'd need to return and manually alter the colors and fonts in your CSS script every time.
With Sass, there's an extraordinary arrangement. Sass permits you to characterize variables so you can later undoubtedly change the values such as color, font size, and borders. Rather than retyping changes over and over in CSS, you can essentially change the values of the variables you like in Sass.
2. Sass Mixins save time
Apart from setting the variables, you can likewise package groups of variables known as Sass Mixins. For instance, if almost all of the pages on a website utilize similar fonts, colors, and border schemes, you can characterize a Mixin that incorporates these values.
Thus, this function allows you to simply call out the Mixin rather than making sure to independently call the text style, shading, and boundary esteems for future web pages.
3. Extended and Inherited functions
At the point when you want distinguished parts of the website from the existing templates, Sass saves time. Let's assume you need a page on your site that generally looks like different pages; however, it contains something new, like a new header. In such a case, Sass permits you to keep or acquire the properties of a Mixin and add individual qualities depending on the situation. Thus you don't have to reclassify everything from the start.
Besides, you can rapidly import the fonts and colors you characterized in a prior Mixin while adding properties for that new header with the help of Sass.
4. Sass functions
You must have built your functions prior if you're known to other programming languages like Python, Swift, or Ruby. The functions acknowledge inputs from users and go through explicit lines of code to perform complex operations. Many programming languages accompany in-build functions. For instance, functions that ascertain averages and string lengths. In any case, assume that you have a particular need, like calculating the word count in each frame of the page.
Sass can permit you to code in the instructions only one time, instead of coding instructions separately on each page. Further, it's not difficult to call your function to play out similar assignments as many times as you want to.
5. Sass assists CSS to work like a programming language
It is not yet clear whether CSS is considered the full programming language. Yet, regardless of where you remain on the point, it's not difficult to see that CSS was intended to give directions on how a website page should look instead of performing dynamic undertakings and working with variables. While every task a developer performs in Sass should be possible in CSS, Sass helps you as a developer, compose code that closely resembles a programming language.
How to Use Sass?
However, after getting all the basic to key details of the Sass developer. Anyone must be keen to use Sass for numerous development purposes. Although, in this section, you will find some essential tips related to Sass.
1. Syntax
Sass comes with two syntax options;
- Indented (Sass)
It uses the .sass file extension and induction instead of brackets. However, it is not compiled with CSS syntax, but it is the fastest way to write.
- SCSS (Sassy CSS)
It uses the .scss extension of the file and is compliant with CSS syntax.
2. Variables
Sass permits the utilization of variables to store data you can use all through your template, the same as in various programming languages. For instance, you can store color value in a variable at the top of the document and afterward utilize this variable when setting the color of your components. This empowers you to change your colors without altering each line independently.
Example;
$font-stack: Helvetica, sans-serif;
$primary-color: #333;
body {
font: 100% $font-stack;
color: $primary-color; }
After that, the CSS will produce is:
body {
font: 100% Helvetica, sans-serif;
color: #333; }
3. Nesting
Nesting is a blade that cuts both ways. While it gives a magnificent strategy to decrease the code amount that you have to write. If you can execute it properly, it can likewise prompt overqualified CSS. The thought is to nest your CSS selectors to imitate your HTML hierarchy.
The below depicts a fundamental navigation style that utilizes nesting:
nav {
ul {
margin: 0; padding:0;
list-style: none;
}
li { display: inline-block; }
a {
display: block;
padding: 6px 12px;
text-decoration: none; } }
The output of CSS is as;
nav ul {
margin: 0;
padding: 0;
list-style: none;
}
nav li {
display: inline-block;
}
nav a {
display: block;
padding: 6px 12px;
text-decoration: none; }
4. Partials
Partials are more modest Sass documents. It could be transferred into other Sass records. Consider partial code snippets. With these code snippets, your CSS would now be able to be secluded and more straightforward to keep up with. A halfway is assigned as such by naming it with the leading underscore: _partial.scss.
5. Import
Import directive enables the developer to import the partial files to the current file to create a sole CSS file. Be aware of the number of exports being done as an HTTP request will begin for each one.
// _reset.scss
html,
body,
ul,
ol {
margin: 0;
padding: 0; }
// basefile.scss
@import 'reset';
body {
font: 100% Helvetica, sans-serif;
background-color: #efefef; }
The CSS corresponding output;
html, body, ul, ol {
margin: 0;
padding: 0;
}
body {
font: 100% Helvetica, sans-serif;
background-color: #efefef; }
6. Mixins
Being the preprocessor, Sass offers the advantage of simplifying complex and lengthy written codes. As such, the Mixins are utilized.
Such as, to incorporate vendor prefixes, mixins would be perfect to do so. Check the example for border-radius:
@mixin border-radius($radius) {
-webkit-border-radius: $radius;
-moz-border-radius: $radius;
-ms-border-radius: $radius;
border-radius: $radius;
}
.box { @include border-radius(10px); }
The @mixin mentioned above at the top is named with the border-radius, and the $radius variable is utilized as the parameters. The same variable could be used to set the value of the radius for every element.
The CSS command produced is;
.box {
-webkit-border-radius: 10px;
-moz-border-radius: 10px;
-ms-border-radius: 10px;
border-radius: 10px;
}
7. Extend/Inheritance
The @extend order has been called one of Sass' most distinctive elements. In the wake of seeing it in real life, it's clear why.
The concept is that with this directive, you will not need to incorporate numerous class names on your HTML components and can keep your code DRY. Further, the selectors can acquire the styles of different selectors and afterward be effectively expanded when required.
8. Operators
The capacity to perform calculations in your CSS permits you to accomplish more, similar to changing over pixels into percentages. After that, access the standard math such as subtraction, addition, multiplication, and division. You can create complex calculations with these functions after joining.
Moreover, Sass incorporates a couple of underlying features to assist with controlling numbers. Functions like percentage(), floor(), and round().
How to Learn Sass?
As Sass is mainly tied up with CSS, it makes sense to first begin learning CSS even before Sass. After learning and acquiring the skills, you would quickly implement the skills while learning Sass. Or it could also be time-efficient while working.
Although, once you fully understand and learn the CSS, it would be easy to learn the Sass language.
Moreover, if you want to begin as a Frontend developer, supplementing your knowledge of CSS would benefit Sass. To prepare for your complex and lengthy web development project, you can join some CSS courses to gain expertise and practical experience.
The CSS programs are:
- Advanced CSS and Sass
- CSS Bootcamp - Master CSS
- Advanced Stylish and Responsive design
- The CSS and CSS3 crash course
Conclusion
In a nutshell, it is crystal clear that Sass is the ultimate scripting language and a great extension tool for CSS.
