Capitalize breadcrumb trail issues

[inveritas]

I am having a really hard time changing the uppercase to capitalization.

 

I have tried the following, to no, or little avail.

 

In breadcrumb, changed:

return $trail_string;

to

return ucwords(strtolower($trail_string));

This would only change the second Word, like this "product Category", instead of "Product Category"

 

In CSS, i tried to add this:

text-transform:capitalize;

 

That did not do a thing either.

 

Any experts here with a clue?
