CSS basics
-
iˇm totaly new - how can I identify the name of the object (in module), I want to modify via custom.css? Let say, I want to modify in default Calendar module the text of todays entries to yellow. How to find in calendar.js, what I want to modify and how to correctly define it in custom.css?
thanks -
@zdenek I would start by searching for
class
orclassName
in the module .js file
Trying to isolate what object is being rendered and see if it has a individual class name or general one (the latter being font sizes likesmall
orlarge
, or font color and weight,light
anddimmed
).if you find a individual class name (like
date
for the default clock’s date) you can easily just change the css for that particular element like this.clock .date { --csscode-- }
There is also the general ones used for headers and text etc. for an example
small
which is used to set the font size in the calendar module (amongst many other).If you want to change the font size of elements with the class name
small
in the calendar you do this like so.calendar .small { font-size: 10px; }
If you want to change the font size of ALL elements that uses the class name
small
you do so by removing the module classname like this.small { font-size 10px }
Good practice is to always add the module class name before the class you are changing (to avoid you messing up other/future modules that maybe uses the same class name).
The module class name is the exact name of the module in the config file and/or the name of the modules folder.
If the text/image or anything lacks a class name you can apply css to elements as well.
so for an example, if you have a module with only one image in it, and you want to change the size of that image . you could do that like this :.modulename img { width: 500px; height: 500px; }
Do note however, this code will change all < img >-elements, ie all images will get the same size.
But the same can be applied to
td tr table p span
etc etc.and if you want to apply css to the entire module (for an example if you want to limit the width of the module) you can do so by
.modulename { Width: 300px; }
There are more tricks to make your custom layout, but these are the basics as I see them.
So I hope this helps! -
@broberg thanks, it helps a lot. Just the basic question I still don’t get - How do I identify “individual class name” in JS file? Is there any key word? I went through code clock.js and there is nothing (for me) like “this is Span named date”. Actually, I want to have time (hours + : + minutes) green. There is timeString, which is I guess variable. There is
div
nameddigital
, but I don’t want to have the wholediv
in green. There is also child namedtimeWrapper
- this is ht right element? but.clock.time { color: green; }
Doesn’t work. Also
.clock.digital { color: green; }
and also
.clock.timeWrapper { color: green; }
doesn’t do anything.
Thanks for help -
First off, you need a space between the two classes
.modulename.class
is not the same as.modulename .class
These are the classes in the clock module
dateWrapper.className = "date normal medium"; timeWrapper.className = "time bright large light"; secondsWrapper.className = "dimmed"; weekWrapper.className = "week dimmed medium"
As you can see there are no individual classname assigned to the secondsWrapper, just the
dimmed
class which is used by the weekWrapper as well.If you look at timeWrapper you will se that it will get css code frome four different classes.
Bright gives the text a white color.
Large gives the text it’s font size.
And
Light gives the text the weight of the font. -
@broberg the secondsWrapper is the only sup tag so it can be accessed by
.clock sup.dimmed
-
@broberg thanks, but still not clear. The missing space is clear. So, what will be in the custom to get time in green? I’m totally lost…
-
.clock .time { Color: green; }
And as @strawberry-3-141 mentioned. Just the seconds
.clock sup.dimmed { Color: #00FFAA; }
-
@broberg ah, thanks. I was trying that, but without the space between classes. This works, perfect, thanks. I hope, I’ll once get it…

Have you tried to use an external Browser e.g. from your Laptop to Open your Magic Mirror Homepage ? (192.168.178.20:8080 for example) there you could use F12(developer Mode) to find out the css class names you Need
