Crediting other sources on a website?

[Anthony]

Okay this may be a dumb question and the title might be just a tad bit misleading, but if i am making a commercial website that will be eventually quite large, do I need to credit say jQuery or Bootstrap in my works? I plan to move away from bootstrap eventually and redesign it using my own css, but I mainly work in php and html so those frameworks aided me alot.

So my question is, do I have to credit those frameworks or even credit things that people made as plug-ins for jQuery and Bootstrap?


P.S. - I have seen alot of them under the apache license so does that mean I just credit that on my site?

Each software package has it's own terms and conditions or umbrella terms like apache should spell that out.
