Question

I’m looking for a regex that will find and replace certain patterns in a CSS file
E.g in the following string:

.boxOneHeading, .boxTwoHeading, .boxThreeHeading
{
    font-size: 18px;
    font-family: MuseoSans500;
    padding: 10px 15px;
    width: 273px;
    background-color: #fbfbfb;
    background-color: #ffffff;
    background-color: #ffcc00;
}

I’m using the following regex: #?[\s]*(.{1})\1{1}(.{1})\2{1}(.{1})\3{1}
This correctly finds:

#ffffff and
#ffcc00

But I’m looking to find only the #ffcc00 values and replace them with #fc0.

What do I add to the regex for this?

Regards,
Jacques

Answer 1

Here is an example:

var color = "#ffcc00";
var replaced = Regex.Replace(color, @"#(\w)\1(\w)\2(\w)\3", "#$1$2$3");
Console.WriteLine(replaced);

But I’m looking to find only the #ffcc00 values and replace them with #fc0

I’m a little thrown off by this, isn’t that basically a find/replace at this point?

var replaced = css.Replace("#ffcc00", "#fc0");
