@Edward 

You're right - unknown html files, unlike safer PDF file, images, word 
documents, etc., are a security risk and people should not 'open/run' by 
double clicking on a html file willy-nilly. 

For instance, when I went through Brian's example *in notepad first, *just 
to make sure...

But I'm a web developper, so I could recognized the imports he made as 
standard bootstrap from known 'content-delivery-networks' or "CDN" which 
are harmless and expected.  *So yeah, people should not open those if they 
are not sure of having confidence in them like I did.*

(But some html file is still less dangerous than a python script, or a 
leoscript that is ran (CTRL+B). because those have network AND full file 
read/write capabilities all over your drives, unlike a html file in a 
browser who can only do malignant stuff in your bookmarks, cookies, open / 
redirect to phishing URLs etc and cannot read arbitrary files.)

But like Thomas pointed out, the more common and dangerous stuff are 
contributions to popular open-source repositories that are then compiled in 
sites/software all over the place! :O 

@Brian

Examples are coming soon!!
