    The key is not to use <xsl:for-each> at all. Use template matching instead.

    <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="html" indent="yes" />
  <xsl:strip-space elements="*" />

  <xsl:template match="/">
    <html>
      <head>
        <title>Title</title>
        <link type="text/css" href="/css/framework.css" rel="stylesheet"/>
      </head>
      <body>
        <xsl:apply-templates />
      </body>
    </html>
  </xsl:template>

  <xsl:template match="page">
    <div id="page-base">
      <xsl:apply-templates />
    </div>
  </xsl:template>

  <xsl:template match="tab">
    <div class="wrapper tab" style="width:{@dim}%; min-width:{@dim}%; max-width:{@dim}%;">
      <xsl:apply-templates />
    </div>
  </xsl:template>
</xsl:stylesheet>

    Result: (also see http://xsltransform.net/gWmuiK6)

    <html>
   <head>
      <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
      <title>Title</title>
      <link type="text/css" href="/css/framework.css" rel="stylesheet">
   </head>
   <body>
      <div id="page-base">
         <div class="wrapper tab" style="width:70%; min-width:70%; max-width:70%;">
            <div class="wrapper tab" style="width:50%; min-width:50%; max-width:50%;">
               alpha


            </div>
            <div class="wrapper tab" style="width:50%; min-width:50%; max-width:50%;">
               alpha


            </div>
         </div>
         <div class="wrapper tab" style="width:30%; min-width:30%; max-width:30%;">
            gama

         </div>
      </div>
   </body>
</html>

    To get rid of the white-space in the output, all you need to do is to add another template:

    <xsl:template match="tab/text()">
  <xsl:value-of select="normalize-space()" />
</xsl:template>

    There are specific cases where <xsl:for-each> is the right thing to use. This is not one of them.

    Whenever you feel inclined to use <xsl:for-each> you should stop and think. In the vast majority of cases <xsl:apply-templates> is what you really want.

    Use <xsl:for-each> only if you find a compelling reason against <xsl:apply-templates>. If you can’t think of one such reason, then there probably is none.

    To output nodes that appear in the input without changing them, add the identity template:

    <xsl:template match="@* | node()">
  <xsl:copy>
    <xsl:apply-templates select="@* | node()" />
  </xsl:copy>
</xsl:template>

    To mute nodes that you do not want in the output, add an empty template:

    <xsl:template match="node/to/match" />
