If you were to install this on a default DNN site, the module does work fine. Unfortunately it is not possible for the module to take account of every different style that someone may wish to apply to a site. So your Sakura skin applies some specific styling overriding the default site, and also applies some specific styling to the Feedback module.
With the upgrade to DNN 6, there is a desire to apply consistent styling across all elements of the interface to get to greater standardisation. Unfortunately again, this will have an impact on the way some skins are applied to sites.
As to a simple way, you could go back to the previous version of the module. It will run on DNN 6. If it works fine for you, why upgrade?
I am prepared to give a hand to making some minor adjustments, but I'm not peraped to do the complete list of tweaks you desire. It would be worth going to the person who designed your skin to ensure it is compatible with a DNN 6 site.
There seem to be couple of major problems:-
- Your site is adding an extra styling tag 'form_style'. Not sure where that comes from, but it is one reason the background is black.
- Secondly your site applies a black background to all text boxes defined as 'NormalTextBox'. I could possibly remove this styling element, but on balance I fear this will affect others who are specifically using the style against the module. I would rather not remove capability to solve a problem on a specific site. It would be better to apply a style to your site that deals with how your site overrides the default.
- You site specifically overrides some height and width elements, these could be removed or edited so that they use default. For instance you say the telephone field is too wide, but this is specifically set in your skin to be 70% of the module width. The difference from previously is that some controls are now not being overridden, which can be corrected.
- The red line is missing because of the form_style tag being added
