"Major mode for editing XHTML documents.
It is based on `nxml-mode' and adds some features that are useful
when editing XHTML files.\\<nxhtml-mode-map>
The XML menu contains functionality added by `nxml-mode' \(on
which this major mode is based). There is also a popup menu
added to the \[apps] key.
The most important features are probably completion and
validation, which is inherited from `nxml-mode' with some small
addtions. In very many situation you can use completion. To
access it type \\[nxml-complete]. Completion has been enhanced in
the following way:
- If region is active and visible then completion will surround the
region with the chosen tag's start and end tag. However only the
starting point is checked for validity. If something is wrong after
insertion you will however immediately see it if you have validation
on.
- It can in some cases give assistance with attribute values.
- Completion can be customized, see the menus XHTML - Completion:
* You can use a menu popup style completion.
* You can have alternatives grouped.
* You can get a short help text shown for each alternative.
- There does not have to be a '<' before point for tag name
completion. (`nxml-mode' requires a '<' before point for tag name
completion.)
- Completes xml version and encoding.
- Completes in an empty buffer, ie inserts a skeleton.
Here are all key bindings in nxhtml-mode itself:
\\{nxhtml-mode-map}
Notice that other minor mode key bindings may also be active, as
well as emulation modes. Do \\[describe-bindings] to get a list
of all active key bindings. Also, *VERY IMPORTANT*, if mumamo is
used in the buffer each mumamo chunk has a different major mode
with different key bindings. You can however still see all
bindings with \\[describe-bindings], but you have to do that with
point in the mumamo chunk you want to know the key bindings in."

The upper half of the image will be used when mouse is out and

Only CSS is used for the rollover. The CSS code is written to the
header part of the file if possible, otherwise it is copied to
the kill ring/clipboard.
The CSS code is built from a template file and the image size.
This might be used for example for creating a menu with
alternatives vertically or horizontally.
Usage example:
If you want to make a small button style menu with images you
can start like this:
<div id=\"mylinks\">
<ul>
<li>
X <a href=\"news.html\">News and Notes</a>
</li>
<li>
<a href=\"doc.html\">Documentation</a>
</li>
<ul>
</div>
Then put point at the X above (this is just a mark, should not
be in your code) and call this function.
It will add some CSS code to in the header of your file. You
may want to tweak this a little bit, see below (or place it
somewhere else). It may look like this:
#mylinks a {
/* Image */
display: block;
background: transparent url(\"img/mybutton.png\") 0 0 no-repeat;
overflow: hidden;
width: 200px;
/* Text placement and size, etc */
text-align: center;
/* You may need to change top and bottom padding depending
on font size. */
padding-top: 11px;
font-size: 12px;
padding-bottom: 9px;
text-decoration: none;
white-space: nowrap;
border: none;
}
#mylinks a:hover {
background-position: 0 -35px;
}
#mylinks li {
display: inline;
padding: 0;
margin: 0;
float: none;
}

nXhtml and can be opened from the nXhtml menu under
