Glad you asked!!! Here is a long answer:-)

JSCode is an XML application. The XML lets us represent programs. We use
XSLT to generate MindScript, NQC and SVG. The SVG displays the program
in blocks like this
  http://jscodee.sourceforge.net/jscode/images/box.png

That image came from an SVG file. The SVG file was generated from an XML
file that was processed by an XSLT stylesheet that converts JSCode XML
into SVG. phew :-)

So, we use our html pages to create XML. To add 1.0 to var1, start here
  http://jscodee.sourceforge.net/jscode/buildBlocks/basic/Add.html

the JSCode XML is
  <block kind="basic" name="Add">
    <param kind="variable">var1</param>
    <param kind="value">1.0</param>
  </block>

We add that XML to a program. We can generate Mindscript
  var1 = 100
or perhaps NQC or Java
  var1 = 100;

or SVG.

The SVG would be something like this:
    <rect stroke="black" fill="forestgreen" rx="5px" y="51px" x="55px"
width="80px" height="60px"/>
    <rect stroke="black" fill="yellow" y="106px" x="65px" width="60px"
height="8px"/>
    <rect stroke="black" fill="forestgreen" y="60px" x="129px"
width="12px" height="42px"/>
    <text fill="white" x="65" y="77">Set</text>
    <text fill="white" x="59" y="91">var1 = 1.0</text>

We get MindScript or SVG or Java because we have XSLT stylesheets that
translate JSCode XML.

I'm updating the XSLT to understand V0.3 JSCode XML. When that is done,
we can update the SVG generated to use CSS. If we want to be able to
change the color of a basic block from forestgreen to some other color,
we will change the SVG something like this
    <rect class="basicBlock" rx="5px" y="51px" x="55px" width="80px"
height="60px"/>
and have CSS that sets or resets the stroke and fill for anything of the
'class' "basicBlock". 

and...

I'm using the SVG to get graphics. Some day when most browsers support
SVG out of the box, we can display the graphics directly. Till then I
generate images so everyone can see them. Some day...

Better?
