CSP violation

[AnaghaForBike]

Hi,

While trying to enable Content Security Policy (CSP), we came cross direct use of inline css in the package webpack-hot-middleware
in file https://github.com/webpack-contrib/webpack-hot-middleware/blob/master/client-overlay.js. i.e.

var color = problemColors[type] || colors.red;
  return (
    '<span style="background-color:#' +
    color +
    '; color:#000000; padding:3px 6px; border-radius: 4px;">' +
    type.slice(0, -1).toUpperCase() +
    '</span>'
  );

Which is flagged as CSP violation. To fix this, we need to replace usage of eval/dynamic function to something safe. Can you please take care in your package webpack-hot-middleware
