Hi,

I am just starting to get familiar with all the ins and outs
of html.
I noticed that you can define a style, e.g.:

x {color: green; font-weight: bold}

and then use <x> and </x> tags in your body. How convenient!

Question is, is this actually allowed under the W3C spec of
the latest version HTML, and is it portable across all/majority
of browers?

I couldn't find this as such answered when googling.
Using Linux/Mozilla, btw.

Thanks for you time.

It's called CSS.

And you can't just use <x>, you need to use real html
elements.

Portable, yes. But not all styles are supported in every
browser. Especially IE isn't completely standards compliant.

No. (Although if you were using a custom XML language you could do this
(making sure you served it as something other then text/html)).

No.

This isn't permitted.

Don't mess with the tags in HTML. Use the set you were given and no
others.

If you _really_ want to do this, then switch to XHTML and use XML
namespacing. This is now perfectly valid (as XML), but it stretches
the boundaries of what's seen as acceptable HTML by most browsers and
validators. It'll give you problems.

The real way to do this is with compliant HTML, using the <span> and
<div> elements, but add a class attribute to them. You now have code
like this:

.x {color: green; font-weight: bold; }

<p>A paragraph with a <span class="x" >green</a> word.</p>


To make this work well, red the HTML specification and the DTD, and
get the distinction cleaqr in your mind about <span>, <div> and the
difference between block and inline elements.

Just swap that </a> for a </span> ;-)

In fact, if that class is supposed to emphasise the word 'green' then this
is much better:

<p>A paragraph with a <strong class="x">green</strong> word.</p>
..x {color: green; font-weight: bold; }
(the font-weight is unnecessary here)

Or even

<p>A paragraph with a <strong>green</strong> word.</p>
strong {color: green; font-weight: bold; }
