Question 1

What is Sass and why should I use it?

Accepted Answer

Sass (Syntactically Awesome StyleSheets) is a popular CSS preprocessor that allows you to use variables, nested rules, mixins, functions, and more, which improves the reusability and organization of your CSS code. It helps in keeping your stylesheets DRY (Don't Repeat Yourself) and makes it easier to maintain and scale larger projects.

Question 2

What is the difference between Sass and SCSS?

Accepted Answer

Sass has two syntax options – the older indented syntax and the newer SCSS syntax. Indented syntax (also known as 'Sass') is the original syntax with more strict whitespace rules, and it doesn't use semicolons or braces. SCSS (Sassy CSS) syntax is more similar to standard CSS syntax, using braces and semicolons, and it is easier for developers familiar with CSS to learn.

Question 3

How do I use variables in Sass?

Accepted Answer

In Sass, you can use variables for reusability and maintainability of your code. To declare a variable, start with a dollar sign ($) followed by the variable name and a colon, then assign it a value. For example:
`$primary-color: #FF5733;`
You can use this variable in your stylesheet like this:
`background-color: $primary-color;`

Question 4

What are mixins in Sass and how can I create one?

Accepted Answer

Mixins in Sass are reusable blocks of code that can be easily included in other parts of your stylesheet. To create a mixin, use the `@mixin` directive followed by the mixin name and optional parameters. For example:
`@mixin box-shadow($x, $y, $blur, $color) {
  -webkit-box-shadow: $x $y $blur $color;
  -moz-box-shadow: $x $y $blur $color;
  box-shadow: $x $y $blur $color;
}`
To include this mixin in your styles, use the `@include` directive followed by the mixin name and arguments:
`div {
  @include box-shadow(0, 1px, 3px, rgba(0, 0, 0, 0.3));
}`

Question 5

How can I perform calculations in Sass?

Accepted Answer

Sass allows you to perform arithmetic operations (+, -, *, /, %) directly on numbers, colors, and variables. For example, you can calculate the width of an element by dividing the total width by the number of columns:
`$total-width: 960px;
$number-of-columns: 12;
.column {
  width: ($total-width / $number-of-columns);
}`
