As it turns out, I can read it after logging out...

... many of us have "Enforce proper nesting of HTML" activated in Display Settings. (I suspect its even default)

But your use of </br> ruins the format, that's broken HTML.

better simply use <p> for paragraphs or at least plain <br> for linebreaks.

Many thanks to all who have contributed to this quest.

From this and other conversations I believe the steps are:
1. choose a 'tool' to create the web site - one Perl based is an MVC toolkit but there a number of other options including Java;
2. check that the chosen tool can do what I want;
3. check that the tool is supported in the user's server;
4. decide which browsers are to be supported.

However perhaps step 3 is done first or at least with step 1 so that time for step 2 is not wasted.

One interesting thing is that I do not think any contributing Monk suggested an MVC toolkit, I just wondered why. I have not looked at its capabilities yet so perhaps there is something there which is a showstopper!

MVCs work well for static HTML, but you asked for porting Tk which has far more possibilities than static HTML.

Thats why we pointed you to JS based Web UI frameworks.

But the discussion concerning the best way to realize DHTML within MVC is still evolving. (eg. MVVM ... etc)

Though I think you will just need to go with simple mojolicious and static HTML, and you just asked a XY problem.

But you'll need a good book about web-technologies to learn the basics or have a look at sites like http://www.w3schools.com/

As long as you are confusing Java and JS there is no help continuing this, perlmonks is not a site for web 101.
