Sass Interview Questions and Answers

Answer: SASS  means Syntactically Awesome Stylesheets as a  CSS pre-processor  is a stylesheet language initially designed by Hampton Catlin and developed by Natalie Weizenbaum.After its initial versions, Weizenbaum and Chris Eppstein have continued to extend Sass with SassScript, a simple scripting language used in Sass files. Sass is a scripting language that is interpreted into Cascading Style Sheets (CSS). SassScript is the scripting language itself. Sass consists of two syntaxes. The original syntax, called the indented syntax, uses a syntax similar to Haml. It uses indentation to separate code blocks and newline characters to sep...

Answer: Sass allows variables to be defined. Variables begin with a Dollar sign ($). Variable assiment is done with a colon(:) SassScript supports four data types: Numbers(including units) Strings (with quotes or without) Colors (name, or names) Boolens Variables can be arguments to or results from one of several available function During translation, the values of the variables are inserted into the output CSS document. In SCSS style $blue: #3bbfce; $margin: 16px; .content-navigation { border-color: $blue; color: darken($blue, 20%); } .border { padding: $margin / 2; margin: $margin / 2; border-color: $blue; } Or SASS style $blue:...

Answer: SASS allows the nested code to be inserted within each other. where as  CSS does support logical nesting, but the code blocks themselves are not nested.    table.hl { margin: 2em 0; td.ln { text-align: right; } } li { font: { family: serif; weight: bold; size: 1.3em; } } Would compile to: table.hl { margin: 2em 0; } table.hl td.ln { text-align: right; } li { font-family: serif; font-weight: bold; font-size: 1.3em; } More complicated types of nesting including Namespace nesting and parent references are discussed in the Sass documentation

Answer: CSS does not support mixins Any repeated code must be repeated in each location. A mixin is a section of code that contains any valid Sass code. Whenever a mixin is called, the result of translating the mixin is inserted at the calling location. Mixins allow for efficient and clean code repetitions, as well as easy alteration of code. @mixin table-base { th { text-align: center; font-weight: bold; } td, th {padding: 2px} } #data { @include table-base; } Would compile to: #data th { text-align: center; font-weight: bold; } #data td, #data th { padding: 2px; }  

Answer: Yes Mixins also support arguments @mixin left($dist) { float: left; margin-left: $dist; } #data { @include left(10px); } Would compile to: #data { float: left; margin-left: 10px; }

Answer: While CSS3 supports the Document Object Model hierarchy, it does not allow selector inheritance. Inheritance is done by inserting a line inside of a code block that uses the @extend keyword and references another selector. The extended selector's attributes are applied to the calling selector. .error { border: 1px #f00; background: #fdd; } .error.intrusion { font-size: 1.3em; font-weight: bold; } .badError { @extend .error; border-width: 3px; } Would compile to: .error, .badError { border: 1px #f00; background: #fdd; } .error.intrusion, .badError.intrusion { font-size: 1.3em; font-weight: bold; } .badError { border-width: 3px; } YES...

Answer: Inline: Inline Style Sheet is used to style only a small piece of code. Syntax:           <htmltag style="cssproperty1:value; cssproperty2:value;">            </htmltag>            Embedded: Embedded style sheets are put between the <head>...</head> tags. Syntax:           <style>               body {   background-color: primary;    }            h1 {   color: red;&nbs...

Answer: The z-index helps to specify the stack order of positioned elements that may overlap one another. The z-index default value is zero and can take on either a positive or negative number. An element with a higher z-index is always stacked above than a lower index. Z-Index can take the following values: Auto: Sets the stack order equal to its parents. Number: Orders the stack order. Initial: Sets this property to its default value (0). Inherit: Inherits this property from its parent element.    Use Z Index if you need to put a background element below a container. You can easily place the background under every elem...

Answer: Constraints are the rules enforced on the data columns of a table. These are used to limit the type of data that can go into a table. This ensures the accuracy and reliability of the data in the database. If any interruption occurs between the constraint and data action, the action is failed. Some of the most commonly used constraints are NOT NULL, PRIMARY KEY, FOREIGN KEY, AUTO_INCREMENT, UNIQUE KEY, etc. syntax  to create a constraint for a table:  CREATE TABLE  table_name (  column1 datatype constraint,   column2 datatype constraint,  ....);       SQL cate...
