Less acos()

The Less acos function is used to specify arccosine value (inverse of cosine) of a number which returns values between 0 and pi.

Acos Function Example

Let's take an example to demonstrate the usage of acos function in Less file.

Create a Less file named "simple.less", having the following code:

Less file: simple.less

Now open the node.js command prompt and 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:

Here, you can see that the font having acos-math function is produced the arccosine value of a specific radian.
