That’s not what the H stands for though… but I get what you’re saying. Because they opened in order, closing in same defined order should be allowed and thus we have all that peeking code to check to see if the next tag is that so we don’t error out and now we no longer conform to XHTML. Because non-engineers are writing HTML. It’s like putting the tires on before the brakes, but brakes after, and expecting it to work.

However because you can be both bold and italic, these should just be flags and that’s how they are now which is why b or i can be closed before b or i. I doubt they are just flags in the code of the browsers though because tags support styles and stuff.
