Update: I’ll recommend to go for Official W3school page having all the tutorials and resources

w3schools W3school whole website mirror download & learn offline

When i published this post then i was not aware any copyright laws and Internet policies. I just mirrored the whole W3Schoool website and put it online for my fellow friends and students.

Thanks to “Hege Refsnes” for his mail regarding my flaws.
In his mail W3schools stated that
