Some of my older customers websites are using HTML4 or XHTML. Should I update customers' website to newer standards? Obviously I don't need to do this, but I have an online portfolio and I'm thinking it would look better on my portfolio if all of my customers' websites are developed with HTML5.

Thanks!

What is the contract or agreement you have with them. Do you need their permission to do the upgrades ? How would it effect their sites and their use of the sites

It won't affect any of their websites. I would simply change some coding here and there, modify some divs into headers and sections, mostly to make the website load faster, and to show off the new standards on my clients' websites. There's no contract involved, therefore there's nobody saying I need permission to upgrade their websites, it's just me.

I'd contact these clients and offer to update their sites as a free service.
That way you look proactive and actually care about your work once deployed.

In this case on a voluntary basis with their permission updating would be acceptable.

Hi,
Would suggest that you first learn which features are implemented, to what extent and some of the work-arounds necessary by some of them. Also, consider if those customers target mobile devices as those often render better pages with HTML5.
Peace,
