IPTables disrupts WebServer Connections on Startup

Alright, this has not happened before in my past experience in coding and using Linux but right now, when I start up IPTables, I cannot access my website in every way possible. SSH still works.

My operating system:

CentOS Linux release 7.2.1511 (Core)


And the things inside my IPTables:


# sample configuration for iptables service
# you can edit this manually or use system-config-firewall
# please do not ask us to add additional ports/services to this default configuration
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -j ACCEPT
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT


If anyone could help me fix this problem, it'd be great.

Answer
iptables -I INPUT 3 -p tcp -m state --state NEW -m tcp -m multiport --dports 80,443 -j ACCEPT

If you could read the manual of iptables, it also would be great.
