HTML5 - leave out (some) end tags

[Robert Prins]

It's allowed to leave out a few end tags in tables (like </th>, </td>, and
</tr>) which would potentially make pages smaller. What's the general opinion on
this?

- go for it?
- use, but with caution?
- bad, it will break things?

It doesn't matter.  In fact you don't need any tags at all to create a web page.  Just a plain text file will work.  You need tags and CSS to style the page but just for fun you can create a text file and browse it in any of the browsers currently available.

Aren't you using any top notch Text Editors to create your webpage?  For example I use VS Code and it has auto-complete that closes all the tags for me in accordance with HTML5 rules.  You don't need to remember anything but it helps if you know something!!

VS Code is one editor but there are others like Brackets, Atom, Notepad++ etc.  All you need is an extension called Emmet and it works wonders!!!  VS code has already got Emmet but in other editors you need to install it.

There are no "pages".

None.

Depends.

Unlikely.

Next time, ask a *smart* question.

First of all, PointedEars' complaint is that you use "page" when I think
you mean "file". Omitting an optional end tag will not reduce the size
of the rendered Web page, but it will reduce the size of the HTML file.

Whether or not you use an optional end tag depends on what follows the
element specified by its beginning tag. Call the element in question A
and the following element B. If B is an element that can be embedded in
element A and alternatively can be outside of A, then you must omit A's
end tag if you intend to embed B; and you must specify A's end tab if
you do not intend to embed B.

All this is something you need to test with the W3C validator. You must
also view the results with at least two unrelated browsers.

The beginner asks for the best path;
the apprentice asks how to walk the path;
the master walks the path, using good judgment on the way.

To avoid troubles, always close your HTML tags properly if they are
supposed to come as pairs, as in WordStar! ;)
