    Polymer or X-tags allow you to build your own html tags. It is based on native browser's "shadow DOM".

    <head>
  <lunch>
    <style type="text/css">
      lunch{
        color:blue;
        font-size:32px;
        }
      </style>
    </lunch>
  </head>

<body>
  <lunch>

    you can use this:

    <!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <title>MyExample</title>
  <style>
    bloodred {color: red;}
  </style>
</head>
<body>
  <bloodred>
    this is BLOODRED (not to scare you)
  </bloodred>
</body>
<script>
  var btn = document.createElement("BLOODRED")
</script>
</html>

    Besides writing an XSL stylesheet, as I described earlier, there is another approach, at least if you are certain that Firefox or another full-fledged XML browser will be used (i.e., NOT Internet Explorer). Skip the XSL transform, and write a complete CSS stylesheet that tells the browser how to format the XML directly. The upside here is that you wouldn't have to learn XSL, which many people find to be a difficult and counterintuitive language. The downside is that your CSS will have to specify the styling very completely, including what are block nodes, what are inlines, etc. Usually, when writing CSS, you can assume that the browser "knows" that <em>, for instance, is an inline node, but it won't have any idea what to do with <dish>.

    Finally, its been a few years since I tried this, but my recollection is that IE (at least a few versions back) refused to apply CSS stylesheets directly to XML documents.

    Creating your own tag names in HTML is not possible / not valid. That's what XML, SGML and other general markup languages are for.

    What you probably want is

    <div id="menu">
    <div id="lunch">
        <span class="dish">aaa</span>
        <span class="dish">bbb</span>
    </div>
    <div id="dinner">
        <span class="dish">ccc</span>
    </div>
</div>

    Or instead of <div/> and <span/> something like <ul/> and <li/>.

    In order to make it look and function right, just hook up some CSS and Javascript.

    I just want to add to the previous answers that there is a meaning to use only two-words tags for custom elements. They should never be standardised.

    For example, you want to use the tag <icon>, because you don't like <img>, and you don't like <i> neither...

    Well, keep in mind that you're not the only one. Maybe in the future, w3c and/or browsers will specify/implement this tag.

    At this time, browsers will probably implements native style for this tag and your website's design may break.

    So I'm suggesting to use (according to this example) <img-icon>.

    As a matter of fact, the tag <menu> is well defined ie not so used, but defined. It should contain <menuitem> which behave like <li>.
