Question

I’m new to Less.

In my script, I’d like to use the width of box1 in box2.

Please review my script.

#box1
{
    width: 1000px;
    height: 500px;
}
#box2
{
    width: #box1.width - 100px;
}

Is it possible or not? If yes, please give me correct Less code.

Answer 1

unfortunatly it is indeed not possible. You could work with variables and do something like this however:

@box1width: 1000px;
#box1
{
    width: @box1width;
    height: 500px;
}
#box2
{
    width: @box1width - 100;
}
