Regex challenge.

I cant tell why it wont let me pass, Its asking me to limit the regex, but i dont really see how.

heres what I have.

// Type inside this function
function isValidHex(text) {
  const hexRegEx = /#([a-f0-9]){6}/i
}

And this is what I get as a failed response.

Your regular expression matches CSS hexadecimal color values, but also matches other values. See if you can limit your regex to meet the requirements.

Here is a regex that will help you pass the challenge:

function isValidHex(text) {
  const hexRegEx = /^#([a-f0-9]){6}$/i
}

The '^' checks for the beginning of the string, meaning make sure the '#' is at the beginning of the string.

The '$' checks for the end of the string, meaning make sure that after 6 hexadecimal values the end of the string comes.
