customize input checkbox color and background in 2018

I need to customize the look and feel of some input checkboxes.

I found this duplicate but the code in the answers have not been updated since 2015

How to style a checkbox using CSS?

Not trying to be picky, but I'm looking for a clean, cross-browser solution, preferably without third party scripts.

<input type="checkbox" class="linksCheckbox" onclick="" 
data-toggle="popover" data-placement="bottom" data-trigger="manual" 
data-html="true" data-content="<ul><li><ul><li><a href='' target='_blank'>test</a></li></ul></li></ul>" 
data-original-title="" title="">

Not sure if I will get in trouble as there are similar questions out there, but they seem quite outdated. Perhaps there has been some developments on this.
