Less isstring()

The Less isstring() function takes a value as a parameter and returns TRUE if it is a string otherwise, returns FALSE.


isstring() Function Example

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

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

Less file: simple.less

  1. div {  

  2.     font:      isstring("variable");     

  3.     background:      isstring(1234);   

  4.     border:      isstring(24px);     

  5.     font:      isstring(7.8%);   

  6.     background:      isstring(#fff);     

  7.     border:      isstring(keyword);                    

  8. }   

Now open the node.js command prompt and execute the following code: lessc simple.less simple.css

Less isstring function1

This will compile the "simple.less" file. A CSS file named "simple.css" will be generated.

For example:

Less isstring function2

The generated CSS "simple.css", has the following code:

Output:

  1. div {  

  2.   font: true;  

  3.   font: false;  

  4.   background: false;  

  5.   border: false;  

  6. }
