Sass @while Directive
The Sass @while directive is very similar to @for directive. It also takes SassScript expressions and iteratively outputs nested styles until the statement returns to false. The value of counter is changed (increased/ decreased) after every iteration.
Sass @while Directive Example
Let's take an example to demonstrate the usage of Sass @while directive. We have an HTML file named "simple.html", having the following data.
HTML file: simple.html
Create a SCSS file named "simple.scss", having the following data.
SCSS file: simple.scss
Put the both file inside the root folder.
Now, open command prompt and run the watch command to tell SASS to watch the file and update the CSS whenever SASS file is changed.
Execute the following code: sass --watch simple.scss:simple.css
It will create a normal CSS file named "simple.css" in the same directory automatically.
The created CSS file "simple.css" contains the following code:
Now, execute the above html file, it will read the CSS value.
