Joomla Template changes

I use the template shape Helix for my Joomla website and would like to change the module positions on the right and left and adjust the modules. Here in a nutshell. 1. The module positions on the right and left should be colored gray with a shadow on the respective side of the content. The modules on the right and left should have a different design. Rounded corners. A line under the heading. In the menu there should also be a line between the individual menu items. Template is delivered using a different template. The actual module on the right should be changed accordingly. In addition to 5 module styles (different colors), where only the color changes. a. gray f2f2f2 b. white ffffff [login to view URL] 26b0cd [login to view URL] c500bd e. yellow fdd30d 2. The distances between the individual modules should be adjusted. I think so 2 px and the distance upwards upwards, I think 5 px. But that's not fixed, I would decide when I see the module.
