can a css line contain multiple colons?

Question

I am writing a Python module that will be doing some css manipulations and modifications. As of my knowledge, the css template is:

selector{
    property:value;
}

my question is, is there any instance where value contains a colon?

The reason for this is that I want to split the lines inside selectors by a colon and essentially grab the property and the value, but if the value has a colon in it, then the entire function will manipulate the css incorrectly.

Answer 1

Yes.

If you specify a filter (IE) it contains a second colon.

Example:

filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#fad59f', endColorstr='#fa9907')

Any CSS property that takes a url could easily contain http:

Example:

background-image: url("http://example.com/image.jpg");
