SingleLine is a CSS Single to Multiline Style Switch plugin for Sublime Text 2.

It will convert between multi-line rules:

body {
    height: 600px;
    width: 600px;
    margin: auto;
    border: 1px solid #000;
}

to

body { height: 600px; width: 600px; margin: auto; border: 1px solid #000; }

-- It also works in less / scss with nested selectors:

.upperclass{
   .middleclass{
        .testclass{
            margin: 20px;
            padding: 10px;
            background: #f00;
        }
    }
}

to

.upperclass{
   .middleclass{
        .testclass{ margin: 20px; padding: 10px; background: #f00; }
    }
}

To toggle between single-line and multiline format you can either select the block or move the cursor inside the block and press ctrl+alt+j.

You can also expand selection to css rule with ctrl+shift+r.
