CSS 101 - Getting started with CSS and understanding how CSS works

Now issue the following command to start MagicMirror in development mode.

npm start dev

This will start MagicMirror in a split screen layout. One side will be the Magic Mirror that you know and love, the other side will be the developer tools console. 

Is this correct? I spent quite a bit of time trying to figure this out. Maybe it’s changed.

The developer tools console is surely just the browser console which is achieved by pressing F12.

When I tried the command:
npm start dev

What this did is direct debug messages into the shell where I typed the command, but didn’t change the display in the web browser. I just thought this might help other people following this guide, which is excellent!

@videogame95 only ever change custom.css

never change any file we ship or any module ships, as it will break update for any of those

so, in a css entry the stuff before the { is called the css selector clause, as it ‘selects’ the elements the info between the {} will apply to

in MagicMirror each module has a container element that uses is name in the class= attribute, so you can select stuff in the calendar module by using its classname

.calendar

I use this to help me remember all the stuff that can go in a selector clause
https://www.w3schools.com/cssref/css_selectors.php

you can use the developers window, elements tab to see and test changes on any element in the active browser window

see here for using the developer window

@sdetweil Hi I’ve add to the custom css
.MMM-Googlecalendar ,
But nothing is changing I just need to add
A border around my text .
}
border around the text

border-color:#000, = block
Border-size-width : 20px
Borde-size-hight: 20px
},

@videogame95 css is case sensitive like everything else

be careful on the selector clause, just module name applies to everything
