MiniCMS Custom Look/Style

[findingcolors]

I installed MiniCMS to display a message in a specific category.

I was wondering if it is possible to edit the look/style of MiniCMS. I don't want the plugin to take the look of my gallery theme (tableh1, tableb, etc). I want it to have custom styling.

I do know HTML & CSS, so adding styling to a style sheet will be no problem, but I cannot find the file in the MiniCMS plugin folder that has the HTML coding to edit the coding (example <div class="maintable"> <div class="tableh1">).

I want to:
1.) Use custom classes
1.) Hide the title
2.) Edit the main content box

I have attached what MiniCMS looks like (with my current theme) & how I want it to look
