Something which you need to consider is the format which you would be handing into potential employers.
If you are hoping to hand in a web page, you would probably want to "render" it and not hand in a piece of functioning code. The reason for this, is if the employer/recruiter is unable to open or correctly read the file, this will decrease your chances of getting the job dramatically. Not to mention many large companies use bots which read CV's for you, See this article which explains that matter all to you.
You would also want to consider what some companies/recruiters may think when they see CV.html
in their email inbox. Some will think its a really smart and creative idea, others may think it is an incompatible file with their computer and may never open it. Leaving instructions on how to open the document may take time which the employer doesn't have.
I'm not saying its a ludicrous idea, I'm saying you need to properly plan it out. Personally, I would keep an online copy on my website, but I would also have an additional copy (Word document or PDF) which could be downloaded and accessed by those bots which I mentioned early.
In programming there are many ways to do the same thing, and it is entirely up to you and your abilities to find what is best.
