/tr
/div

the part that starts with div, thru end div, you can insert into the wrapper div innerHtml

head and body are controlled by MM

there are default classes in ~/MagicMirror/css/main.css
you can add more by adding them to ~/MagicMirror/css/custom.css

you can also have a css file local to the module folder, and include it with the getStyles() method response
(and those can be overridden in the custom.css)

Give it a try, you’ll get it pretty quick

Okay, so I I have to create another html tag or will it inherit the master?

just design your page like always… understanding that your ‘body’ content should be as specific as possible…

a table, or some such, small, say 1/4 page width or smaller… my charts are 400x400 pixels on a 1920/1280 display.
…the head, and body tags themselves are supplied my MM…

look at the MM index.html
each ‘position’: value matches with one of those areas… modules are placed from config.js, top to bottom, fifo.
second module is pushed down by 1st in that same area…screen is clipped at the edges (main.css, body overflow:hidden)
