Uikit CSS toggle-style checkboxes

[Chris Bennett 24]

Not sure where I originally saw it while lurking around the forums, but someone, somewhere at some time was asking about styling Uikit checkboxes as toggle-style switches, much like the ones at the bottom of this post asking me if I want to be notified of replies.

So here is my humble offering, rough and ready,  which can be thrown in at the bottom of your Uikit css as a starting point.

Everything is based on ems and rems, so you can increase size as you desire by altering the single instance of font-size.

It only targets single instances of labels within a specific field to a) try to limit unintended consequences and b) because in those cases it often seems more user-friendly to have an on/off binary switch rather than a checkbox. It's still totally a checkbox, just styled differently.

Didn't realise I wouldn't be able to edit the original post with inevitable tweaks and changes.
Whoops, sorry about that.

Below is an extended version dealing with a few more common admin backend use cases.

	box-shadow:inset 5em 0 0 0 #DDD;
	flex-shrink:0;
}

p.template-checkboxes input[type=checkbox].uk-checkbox {

Really great ! Thanks for sharing !

Is there a SCSS version of it ?

[Chris Bennett 24]

Sorry flydev, not at the moment. I am an old-school, banging-rocks-together, CSS kinda dude, so am not experienced with compilers in general, yet.
I get why they are very useful, I just haven't *needed*  to use them in the past.

It is something I plan to work towards with processwire after many years of static sites.. Using variables are starting to make great sense.

It's still very much a  work in progress and is not very fancy or tricky, so it should be able to slot in somewhere without much hassle.

[flydev 1,424]

I fully understand, same thing here and I still don't know how it really work.. I can use, modify or compile it but not write a single SCSS, LESS or whatever file.. !  I first put my hand into theses things recently with the AdminThemeUikit and AdminThemeBoss. But once you get it, I must admit that they are usefull.

A small advice to get started with theses things, take a look there from @Noel Boss :

Anyway, great addition, thanks again

I've just stripped out the ":after" declarations nesting them inside their respective selectors

 Thanks @Chris Bennett ! Just integrated it in my latest release: 

Looks nice!

[flydev 1,424]

@Chris Bennett @Noel Boss, I don't know how look your user edit page, but on mine, the checkboxes are not customized. It was also necessary to add the rule for :

.InputfieldCheckboxesStacked { }

 

Below the modified @3fingers version :

@flydev I did not use the code as is but changed and extended some of it.
