What are such best practices?
Well, since you are so determined on having a nostalgic browsing experience, having a correct DOCTYPE for HTML4 would be a start.
But honestly, closing your tags and writing their names correctly would be a way better start. You and your website are one of the reasons why HTML parsers are so fucking ridiculously complex beasts, because while you claim you can write websites, you produce terrible HTML. Also, strings in HTML use double quotes (ie "") not single quotes (ie '').
And then this whole thing with inline styles... CSS was created to separate design from content, and merging them back together is kind of counter intuitive. Having design and content neatly separated into two documents allows you to re-use one stylesheet that the browser can efficiently cache across all your pages. But hey, I guess Netscape 3 didn't do that, so no need for that fancy stuff, right?
