This is my very first webpage (so please be nice!), using the tutorial at some website I found! As of now, I know about the header elements, as well as block and inline elements!
So, why exactly do I use the phrase, "Hello World?" Simply put, "Hello World" is the first program students learn for pretty much any language - to quote Wikipedia:
While small test programs existed since the development of programmable computers, the tradition of using the phrase "Hello world!" as a test message was influenced by an example program in the book The C Programming Language. The example program from that book prints "hello, world" (without capital letters or exclamation mark), and was inherited from a 1974 Bell Laboratories internal memorandum by Brian Kernighan, Programming in C: A Tutorial, which contains the first known version:
main() { printf("hello, world"); }
If you couldn't tell, the output of the above code is hello, world
Look at that - you can nest elements! This paragraph contains a blockquote, which contains a blockquote, which has a <pre> tagcode inside of a <pre> tag!!
