Is using without enclosing tags dangerous? [closed]

Answer 1

It would be up to the browser's implementation to decide what to do with it. If you really want to do this, test it out in all the browsers you want to support before using it.

Also note that the browsers' behaviours might change in the future.

Answer 2

That's the same as using <td> tags inside <p>. Sure, it might work somehow on some browsers, but it will definitely be broken. The behaviour of such construct is undefined, there are no guarantees on how it will work on different browsers. Not to speak of accessibility, screen reader programs would be quite perplexed about this kind of structure.

Why can't you use a proper <ul> or <ol> tag? It can be styled and handles the same way as a <div>.

Answer 3

I can't see why it wouldn't display correctly, while it's not meant to exist on it's own it'll render fine.

You should probably put it in a <ul> there are no benefits to the markup you are using over not doing it properly.

Answer 4

It's not valid markup at all. If it gets displayed correctly, it's only a matter of luck.

As you seem to define dangerous by "break in browsers for the end user's ability to view the page as intended", then yes it's dangerous.

Browsers are trying their best to compensate for invalid markup but there is no guarantee at all your page gets displayed correctly.

You say validation is the least of your concerns, please reconsider and have a look at Why Validate?. If you care about your page being displayed correctly with no quirks, then validate.

EDIT: I submitted your fragment to browsershots.org to see how it gets rendered by different browsers.

Answer 5

This is echoing everybody else's answer, in part: with any markup, there's an empirical question of whether it works or not on the browsers that you are testing it on. You tested it on all your browsers, and your happy. That's cool and is a huge part of the work.

But beyond that, there's also the hypothetical question of how well it might work on browser-platform combinations that you haven't tested, either because:

1. you didn't include them in the test set
2. they don't exist yet or
3. they're not available for testing (web-crawlers, for instance)

For this set, which always becomes relevant sooner or later, you should follow standards -- when possible -- and use the enclosing UL or OL tags (in this case).

It's also worth mentioning that it makes the LI tags easier to track down if you are doing scripting, or if someone is doing scripting on your page (e.g., Greasemonkey).
