I think you’ll find that it’s because of the .cellDate property - it’s set to flex-grow: 3

Almost everything on that line is also connected to .cellHeader.

I disable the CW line manually (from habit, don’t know if it’s an option to do in config) along with a few other modifications (including eliminating weather through config):

.CX3 .cellHeader {
  text-align: right;
  height: var(--cellheaderheight);
  padding: 2px;
  display: flex;
  flex-direction: row;
  justify-content: space-between;
  font-size: 100%;
}

/* Disable CW date */
.CX3 .cw {
	display: none;
}

This results in the header taking up the entire space.

Look for the .cellHeader properties in the main CSS file, and copy them over to your custom.css to mess with them all you want and see what happens.

Pay special attention to justify-content in .cellHeader in combination with the flex-grow in .cellDate

@BKeyport you can override in dev window, no need to copy

[BKeyport]

@sdetweil right, but once you have the changes you want, you have to figure out how to implement them, and I’ve noticed with CX3 and some other modules, sometimes the dev window flat out lies where to stuff the CSS for final.

[sdetweil]

@BKeyport you copy/paste from the top right to custom.css
with the selected selector from right of bottom left pane w the modulename class prefix

will post images later, in car now

[sdetweil]

@BKeyport never seen it lie

[p1lspeda]

Thanks folks,
much appreciated that you invest your free-time to help simpletons like me.
My custom.css now includes

.CX3 .cellHeader .cellDate {
        flex-grow: 0;
}

.CX3 .cw::before {
        content: "CW";
        margin-right: 0px;
}

which seems to achieve what I was/am looking for.

@BKeyport here is my dev window steps
the background area for the today highlight is smaller than the font size (set with the cx3-… properties)

now w the element selected

can’t copy/paste the selector list bottom,
so copy the element it self

and paste into editor on custom.css

now keep/remove the text to match the bottom selector row

div .cell.today.thisMonth.thisYear.year_2025.month_3.date_25.weekday_2 div.cellHeader div.cellDate

add the module name in front

.CX3 div .cell.today.thisMonth.thisYear.year_2025.month_3.date_25.weekday_2 div.cellHeader div.cellDate {

}

then copy the change in the dev window

and paste into custom.css inside the braces of the thing you just added

.CX3 div .cell.today.thisMonth.thisYear.year_2025.month_3.date_25.weekday_2 div.cellHeader div.cellDate {
 height: 1em;
text-align: left;
}

now. you MIGHT know (or not) that we ONLY need to target the ‘today’ and ‘celldate’ classes , not JUST this ACTUAL date (mar 25)

so we should shorten the selector… so it also works tomorrow

.CX3 div .cell.today div.cellDate {
 height: 1em;
}

every module it different, so it takes some thinking about what you are seeing

Hi - I have struggled with this for the past 24 hours and I cannot figure it. If someone can provide me ELI5 instructions I would appreciate it as CSS is not my strong suit. I am changing things in the custom.css file - perhaps what I want to do cannot be changed there.

I would like to change the width and height of the calendar boxes, regardless of the data in them. I have figured out how to increase font size, but the cell/box size does not grow dynamically as thought it would. Any help appreciated.

.CX3 {
  font-size: 20px;
}

[sdetweil]

@cricket you need to change the – variables he has defined… see the README.md file
https://github.com/MMRIZE/MMM-CalendarExt3?tab=readme-ov-file#styling-with-css

from configuration means

fontSize	'18px'	Default font size of this module.
eventHeight	'22px'	The height of each event.

@sdetweil
Believe me I have and have looked at it at least times, I simply don’t understand how to achieve what I am asking. I have figured out the font size by what I included above. But I don’t understand how change the size of the day cell/box even if it is empty.

[sdetweil]

@cricket so, ‘simple’ way is to add more event lines to the box which will make it taller

maxeventlines: 10 or whatever

maxevents*lineHeight = size of box.
lineHeight = fontsize+4 (in the default config)

all of the important values are configurable in the module config, so you dont have to mess with css for this

Thank you very much for this - I will give this a go!

@sdetweil
Outstanding - this did exactly what I was looking for. I also a the appreciate the explanation. I am catching on slowly!

Last thing for me on this - is there a way to move the module down? My screen is portrait and it covers up some top modules. I am trying to move the module down with

.region.middle.center {
        top: 50px;
}

I have experimented with positive and negative numbers with wild results. It pushes the calendar off the screen a the top and only shows about half LOL.

Should I be modifying this in the module section of the config.js file or in the custom.css file as above. With the right commands of course.

[sdetweil]

@cricket awesome!

[sdetweil]

@cricket move,
put it on the bottom instead of center

[cricket]

@sdetweil
Not sure if this is the “right” way but this worked:

.region.middle.center {
        margin-top: 150px;
}

Even a blind squirrel… :-).

Hi folks,
it’s me again with a (probably) simple solution.
After I did a complete fresh install and re-added my custom.css, my Calendar looks a little odd - it triggers my OCD.

I guess I do not need to explain what is bothering me.
Why is the weather info centered on monday ?
How do I get CW, Weather and Current Day in 1 single line ?

This is my current custom.css for MMM-CalendarExt3

.CX3 .cw {
        color: white;
}

.CX3 .weekend_2 {
        color: white;
}

.CX3 .weekend_1 {
        color: white;
}

.CX3 .event {
        border: none;
}

.CX3 .cell {
        border: none;
        background-color: rgba(255,255,255,0);
}

.CX3 .cellHeader .cellDate {
        flex-grow: 0;
}

.CX3 .cw::before {
        content: "CW";
        margin-right: 0px;
}

Ideas/Tips/Hints are much appreciated.
What I do not understand is, that this has changed after I did a fresh install but re-added my backed up custom.css :-/

did you edit the css in the module folder??
this is WHY you DON’T do that…

[sdetweil]

@p1lspeda first thing is to disable your settings in custom.css and see what the module provides
