Concatenate string and var less css

Question

Can anyone please tell me how to concatenate a var and a string in LESS so I don\'t have the space between them?

I have the following code:

.text(@si         


        

Answer 1

this is how I recently solved a similar problem.

.text(@size: 10) {
  font-size: e(%("%dpx", @size));
  line-height: e(%("%dem", @size/10));
}

The %("string", value) function simply format a string and so it take the %d inside the string and transform it in whatever is value. an example here: http://cdpn.io/hAbwl

Hope this can help.
