I am trying to create a split-button in my website (ASPNET WebForms). So far the only split-button implementation I like is the one from Bootstrap. I am not using any other feat
I'm not sure if this will answer your question exactly but what I do in all my BS 3 projects is:
In my header:
In custom.css
@import boostrap.less // or the fully compiled bootstrap css
// all your custom stuff, overrides, etc. down here
This way we load up boostrap first but anything custom you want to do will be loaded last meaning your chances of overriding are high and won't cause conflicts. Also it's one line and a lot cleaner for your
