Is it bad practice to comment out single lines of CSS with //?

Question

I have recently started using // to \"comment\" out single lines of CSS code. I understand that I am not actually commenting out the line; I am just breaking it

Answer 1

I use // to 'comment out' lines in .css files all the time. Because it's bound to a shortcut in Vim, and I always forget what I am editing. In JavaScript it's really handy to comment out blocks of code, test the code, and 'comment in' the block of code again (shortcuts, yes).

But when I tidy op my .css file, I use the following constructs to more easily move declarations in and out of scope:

.pin {
    /*
    position: absolute;
    background: url(buttons-3x3.png);
    background-color: red;
    */
    height:50px;
    width:150px;
    position: relative;
}


.shadow {
    margin-top: 25px;
    margin-left: 25px;
    margin-left: 60px;
    width:50px;
    height:50px;
    background: url(playground.png) -400px -100px;
    position: relative;
    position: absolute;
}

In .pin I can remove a line and add it to the commented area and vice versa. In .shadow I just redeclare the same property with a different value.

It's a pain.
