How do you usually go about theming or customizing Bootstrap for your app from a Full Stack Developer perspective? Lets say the app I’m developing has typical features of a social login, dashboard and an interactive messaging forum (not as advanced as this one, but a basic one will do).
If I just use the standard Bootstrap, it is just too commonly found everywhere. Second option is to use an open source one available at bootswatch.com. Or finally, you design your own by writing less/scss code? How feasible is that approach, TBH? Do backend devs who are actually programmers in php, python, etc. able to learn scss/less in a short period of time (provided they already know basics of html/css/js/jquery)?
In short, is it a DIY approach, or do you fetch each individual css/js component from a library and then build a template?
