Remarks

  1. Since filter is an experimental feature, you should use the -webkit prefix. It may change in syntax and behavior, but the changes are probably going to be small.

  2. It might not be supported in older versions of major browsers. It might be entirely unsupported in mobile browsers.

  3. Due to its relatively limited support, try to use box-shadow instead of filter: drop-shadow(). Use opacity instead of filter: opacity().

  4. It can be animated through Javascript/jQuery. For Javascript, use object.style.WebkitFilter.

  5. Check W3Schools or MDN for more info.

  6. W3Schools also has a demo page for all the different type of filter values.
