That's really a pitty (again)
BUT my guess is you have the very same errors in your prosilver based style (believe me it was alot what I saw).
I could not test the other styles because they are not set to default but if you like I will try again when it's set up differently.
Or you could try to see for yourself .. ever heard of W3C validator for html and css? (google it)
Tools I can do without either, because we all make mistakes
I understand the learning curve is steap but that's mostly because you are trying to start with too complicated edits maybe? (and all at once without checking each edit before editing more, it would save you from collecting hundreds of errors in a short time (for example <br> does not exist, <br />
does.
Just some advice meant to help.
