\wxheading{Cells}
You can divide any text (or HTML) into small fragments. Let's call these
fragments {\bf cells}. Cell is for example one word, horizontal line, image
or any other part of document. Each cell has width and height (except special
-"magic" cells with zero dimensions - e.g. color changers or font changers).

Use \helpref{OpenContainer}{wxhtmlwinparseropencontainer} to open new

-{\it sub-container} of the old one. (If you want to create new container with

Use \helpref{CloseContaier}{wxhtmlwinparserclosecontainer} to close the
-container. This doesn't create new container with same depth level but

it returns "control" to the parent container.

You can see that there was opened container before running the code. We closed
it, created our own container, then closed our container and opened
new container. The result was that we had {\it same depth level} after
-executing. This is general rule that should be followed by tag handlers :
+executing. This is general rule that should be followed by tag handlers:
leave depth level of containers unmodified (in other words, number of
OpenContainer and CloseContainer calls should be same within \helpref{HandleTag}{wxhtmltaghandlerhandletag}'s body).
