Contrast Function Example
Let’s take an example to demonstrate the usage of contrast color operation in Less file.
Create a HTML file named ?simple.html?, having the following data.
HTML file: simple.html
Now create a file named “simple.less”. It is similar to CSS file. The only one difference is that it is saved with “.less” extension.
LESS file: simple.less
Put the both file “simple.html” and “simple.less” inside the root folder of Node.js
Now, execute the following code: lessc simple.less simple.css
This will compile the “simple.less” file. A CSS file named “simple.css” will be generated.
For example:
The generated CSS “simple.css”, has the following code:
Output:
