Create object from string in Coffee script

I'm sure there is a much cleaner (and coffee native) way to do this.

What I need is to go from

background: url(../assets/logos/logos.jpg) no-repeat; background-position: 0px -50px; height: 50px; width: 250px; margin: 0 auto;

into

{ background: 'url(../assets/logos/logos.jpg) no-repeat',
 'background-position': '0px -50px',
  height: '50px',
  width: '250px',
  margin: '0 auto' }

which is basically

• take a string


• split it by ;


• split them by :


• first() is the key and second is the value

Here is the code I currently have to do this conversion

  items = {}
  log style
  for item in style.split(';')
    if (item)
      items[item.split(':').first().trim()] =item.split(':').second().trim()
  log items

For reference here is where this code snippet fits (I'm creating a unit test to test CSS)

  check_Generic_Footer_Css = (html, baseUrl, next)->
    juice   = require('juice')
    cheerio = require('cheerio')
    juice.juiceContent html, { url: baseUrl}, (err, cssHtml)->
      $css = cheerio.load(cssHtml)
      footer_Attr = $css('#footer #footer-img #si-logo').attr()
      footer_Attr.assert_Is {  id: 'si-logo'
                             , style: 'background: url(../assets/logos/logos.jpg) no-repeat; background-position: 0px -50px; height: 50px; width: 250px; margin: 0 auto;' }

      style = footer_Attr.style
      items = {}
      log style
      for item in style.split(';')
        if (item)
          items[item.split(':').first().trim()] =item.split(':').second().trim()
      log items

      background =items['background']

      items['background'].assert_Is('url(../assets/logos/logos.jpg) no-repeat' )
      next()
