Region/module positioning on Servermode (on docker, Synology) and client (web-browser)

[skibro]

Hi MagicMirror Builders!

I’ve got stuck with the positioning of modules/regions. My setup:

MagicMirror2 running in servermode in a docker container on a Synology.
The client would be a tablet (untill I fix a monitor and a PI), I am planning to show the info board in a browser.

Setup is finished, I am able to install/config modules, apply css. The problem is that when I open the ip of the mirror in a browser, the alignment of the regions is not ok. It seems like the _left and _right regions are just on top each other. I tried to modify the “body” in the custom.css, it works (the modules become wider), but the alignment is the same, I can not place the top_left and top_right regions nex to each other.

I have no experience in css or js, but tried to find a solution on the forum, without luck. Can you please point me in the right direction? How could I set the window size for the MM?

My modules config:

modules: [
		
		{
			module: "clock",
			position: "top_right"
		},
		
		{
			module: "currentweather",
			position: "top_left",
			config: {
				location: "Lidingö",
				locationID: "",  //ID from http://bulk.openweathermap.org/sample/; unzip the gz file and find your city
				appid: ""
			}
		},
		{
			module: "weatherforecast",
			position: "top_left",
			header: "Weather Forecast",
			config: {
				location: "Lidingö",
				locationID: "",  //ID from https://openweathermap.org/city
				appid: ""
			}
		},
		{

Thanks in advance!
