Types of webpage error codes - http-status-code-404

Question

I am creating a webpage for another company. If this website is created wrong or if there is any errors I can't sell it to the company. I know there is several types of http status codes. I know for example there is the 404 error when the address is wrong but I don't know any of the other http status codes. Can anybody please tell me what they are?
EDIT:
I also want to know wich can be styled by me. So for example a 404 status code can be styled on my own way by saying the location of my document in an .htaccess file

Answer 3

All the possible codes. Mostly for handling error scenarios we care about 400 and 500 series.
Solution:
check the http response code belongs to 400 or 500 series, if yes then redirect the page to some error page defining the error message what went wrong or define some custom messages to show to client (more meaningful to end users). That way the application would handle error scenarios gracefully.

Answer 4

There is a few places to look at:
HTTP Status Code Errors,
List of HTTP status codes - Wikipedia
HTTP Error and Status Codes Explained
100-199 : informational status
200-299 : success status
300-399 : redirection status
400-499 : client errors
500-599 : server errors
Actually it's just the 400-500 codes that's important. Others is also important but not as important.
