@Dimonic every region has the class region, the position gets splitted by underscore. then you have the class top and center

the selector will match any tag which has the class region and top and center

e.g. anytag class="region top center"

EDIT: it wont let me write real html code < nor <

@Cliff365 I released a new version, please update the module again.

@PointPubMedia the hour and the minute are in the same div which makes it not possible to do it just in css, but
there is a config option which adds a wrapper around the minutes, which is perfect for this task.

the selector would be probably something like this:

.clock div.time.bright.large.light span.bold {
  //set the font size here
}

therefore you also have to add clockBold: true to the config

if you dont like the bold effect you can overwrite it as well where you change the font size

@broberg the secondsWrapper is the only sup tag so it can be accessed by .clock sup.dimmed

@nagaculun did you consider using the config option analogSize for the clock module?

analogSize: Specific to the analog clock. Defines how large the analog display is. Possible values: A positive number of pixels Default value: '200px'

Furthermore the value can have even more units than just pixels, as it uses the standard width and height property for it.
Check out the property values section here https://www.w3schools.com/cssref/pr_dim_width.asp

@Da-ne-ezy custom.css

.MODULENAME {
  border: 2px solid white;
}

This should not work, as the getStyles function of the module gets just executed once when the mirror boots. I would suggest to create some classes like morning, afternoon, evening, … and in the module you load the css file with those classes, then create an interval which checks the current time of the day. based on that you query for the body like var body = document.querySelector('body'); and set the specific class body.className = 'morning';
