Apart from the pointless XMLism, the slash, that's usually acceptable. On
the other hand, if you want to use <brto stop floating, you could just as
well use <br clear="all">. And on the third hand, you could do the logical
thing and assign clear: both to the first element after the elements that
you float. After all, there's really no need to introduce artificial
markup - except in rare cases where some external force prevents you from
knowing what comes next (e.g., the floated stuff is a fragment of code that
is included in different contexts on different pages).
<div style="clear: both" />
That's a pointless risk, since the XMLism _should not_ (by XML specs) be
used for elements other than those with EMPTY declared content, in any
context where the document might be processed by XML-ignorant software
(effectively, legacy web browsers and relatives).
and some even say it is best to
<div style="clear: both; height: 1px" />
That's even worse, even though the extra 1px vertical spacing probably
doesn't cause a catastrophe.

<bris inline rather than block, so it's really the wrong element to
use here. Personally I use <hr>, and with CSS to either hide it, or to
make it into a decorative fleuron. You can use <divinstead though
(or <p>, or almost anything, with varying levels of semantic
appropriateness )
If you do this
<body>
<div>...</div>
<br>
<div>...</div>
</body>
That's actually invalid in a Strict doctype.
<div style="clear: both" />
As a totally separate issue, you're now concerned about XHTML empty
elements.
This is reasonable for XHTML as pure-XML, but that's not a good idea
for web use and you should be using Appendix C XHTML instead -- or
else just HTML 4 and not XHTML at all.
An empty <brelement should be <br /in XHTML Appendix C, as should
other tags that are defined as EMPTY in the HTML DTD (i.e. <hr>)
An empty <div></divelement should be <div></divin XHTML Appendix
C, as should other tags that aren't defined as empty (i.e. <div>,
<span>, <petc.)
<div style="clear: both; height: 1px" />
Clear is clear, there's no need (AFAIK) to have a non-zero height. If
there's some obscure case where this is useful, perhaps someone could
cite a clear instance.

Yes, exactly, and technically speaking browsers should ignore
'style="clear: both"' on <brunless you also change it to display:
block. But none of them do, they all treat it as equivalent to <br
clear="all">

That's CSS 2.* behaviour. In CSS 1 it was applicable to all elements.
It's still discussed in CSS 2.1 in terms of how a renderer might
choose to process it, should it be encountered on an inline element
(i.e. they don't advise setting it when authoring inlines, but (for
backwards compatibility) they suggest not simply ignoring it as
inapplicable)
Also sprach Su************@ gmail.com:
[Force an element to enclose all its floated children]
<br style="clear: both" />
is there a standard way to do it, especially with all the browsers
being different?
Here's what I do:
HTML:
....
<head>
...
<link rel="stylesheet " href="common.cs s">
<!-- The following is a "conditiona l comment" - M$ proprietary stuff -
will be read by IE only -->
<!--[if IE]><link rel="stylesheet " href="ie.css">< ![endif]-->
</head>
<body>
...
<div class="enclose" ... Floated content ... </div>
...
</body>
....
common.css:
....
/*
For standards compliant browsers supporting the "content" property (IE
doesn't):
Insert a dot "." at the end of the container and style it so that it is
invisible and clears the float.
*/
..enclose:after
{
display: block;
content: ".";
height: 0;
visibility: hidden;
clear: both;
}
....
ie.css:
....
/*
IE doesn't support the "content" property, but encloses everything if the
container has a proprietary internal property called "layout" which it can
gain either by setting an explicit height or using the - proprietary - zoom
property. As IE handles height as min-height (which in turn it doesn't
support), the container will still expand to hold all its contents even if
height is set to 1px. IE7, however, seems to implement height correctly, so
that cannot be used for this browser version. "zoom", on the other hand, is
not supported by IE5.0. So we set both and set height back to "auto" for IE
browsers 5 (IE5.0 will choke on the backslash character in he\ight thus
ignoring the auto value and retaining the 1px).
*/
..enclose
{
height: 1px;
he\ight: auto;
zoom: 1;
}
....
