LESS - Named Parameters
Description
Mixins provide parameter values instead of positions by using their names. Parameters don't have any order for placing values and they can be referenced by name. The result of named parameters is easier to read and provides clear codes.
Example
The following example demonstrates the use of named parameters in the LESS file −
<!doctype html> <head> <title>Named Parameters</title> <link rel = "stylesheet" href = "style.css" type = "text/css" /> </head> <body> <h2>Example of Named Parameters</h2> <p class = "class1">Hello World...</p> <p class = "class2">Welcome to Tutorialspoint...</p> </body> </html>
Next, create the style.less file.
style.less
.mixin(@color: black; @fontSize: 10px) { color: @color; font-size: @fontSize; } .class1 { .mixin(@fontSize: 20px; @color: #F5A9D0); } .class2 { .mixin(#F79F81; @fontSize: 20px); }
You can compile the style.less to style.css by using the following command −
lessc style.less style.css
Execute the above command; it will create the style.css file automatically with the following code −
style.css
.class1 { color: #F5A9D0; font-size: 20px; } .class2 { color: #F79F81; font-size: 20px; }
Output
Follow these steps to see how the above code works −
Save the above html code in the named_param.html file.
Open this HTML file in a browser, the following output will get displayed.
